Herbicidal Sulfonamides

The following publications disclose herbicidal sulfonylureas related to the sulfonamides of this invention in that substantially all disclosed compounds contain the characteristic sulfonylurea moiety. There are sufficient distinctions, however, to render these representative publications more useful as a backdrop against which to appreciate the instant invention rather than as suggestive of it.

Compounds of Formula I are prepared by the methods shown below in Equations 1, 2, 3 and 4, wherein J, W, A and R are as previously defined. The method of choice for the individual compounds of Formula I will be readily apparent to those skilled in the art.

Equation 1 illustrates the reaction of sulfonamides II with the phenol ester of the appropriate carbamic acid or thiocarbamic acid of Formula III in the presence of a tertiary amine base such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). Similar coupling methods are described in EPA 70,804. ##STR10##

The reaction of Equation 1 is best carried out at about -5.degree. to 25.degree. C. is an inert solvent such as dioxane or acetonitrile for 1 to 24 hours, optionally under an inert atmosphere and in the presence of an equimolar quantity of DBU. The desired products of Formula I can be conveniently isolated by acidifying the reaction solution with aqueous hydrochloric acid or acetic acid and filtration. Alternatively, the aqueous layer can be extracted with a solvent such as methylene chloride. Drying and evaporating the solvent affords the desired product.

The phenylcarbamate and phenylthiocarbamate intermediates of Formula III can be prepared by methods, or obvious modifications thereof, described in South African Patent Application No. 82/5671 and South African Patent Application No. 82/5045.

Equation 2 illustrates the reaction of sulfonylisocyanates and sulfonylisothiocyanates of Formula IV with the appropriate heterocyclic amines of Formula V. ##STR11##

The reaction of Equation 2 is best carried out in an inert solvent such as methylene chloride, tetrahydrofuran, toluene or acetonitrile at a temperature between about 0.degree. and 80.degree. C. A catalytic amount of 1,4-diazabicyclo[2.2.2]octane (DABCO) can be used to accelerate the reaction. In cases where the Products are insoluble in the reaction solvent, they can be isolated by simple filtration. Soluble products can be isolated by evaporation of the solvent and trituration of the residue with solvents such as 1-chlorobutane, diethyl ether or ethyl acetate, and filtration.

Sulfonyl isocyanates IV (W.dbd.O) can be prepared directly from the corresponding sulfonamides II according to the procedures described in Ulrich et al., Newer Methods of Preparative Organic Chemistry, Vol. VI, page 223 to 241, Academic Press, New York and London, W. Foerst Ed. By this two-step procedure, sulfonamides are converted to isolatable n-butylsulfonylureas which are reacted further with phosgene and a tertiary amine catalyst to form sulfonyl isocyanates. The analogous one-step procedure can be employed by using the method described in U.S. Pat. No. 4,238,621. Alternatively, sulfonamides can be reacted with thionyl chloride to form intermediate N-sulfinylsulfonamides, which upon exposure to phosgene in the presence of a catalytic amount of Pyridine, provide sulfonyl isocyanates. For additional details, see Ulrich et al., J. Org. Chem., 34, pages 3200 to 3202 (1969).

Sulfonyl isothiocyanates (iv, w.dbd.s) are prepared from the corresponding sulfonamides by reaction with carbon disulfide and potassium hydroxide followed by treatment of the resulting dipotassium salt with phosgene. Such a procedure is described in Arch. Pharm., 299, 174 (1966).

Equation 3 illustrates the reaction of a sulfonyl carbamate or thiocarbamate of Formula VI with an appropriate heterocyclic amine V. ##STR12##

The reaction of Equation 3 is carried out at about 20.degree. to 100.degree. C. in an inert solvent such as p-dioxane for 0.5 to 24 hours. Additional details concerning the general coupling reaction to prepare sulfonylureas can be found in EPA 44,807. The product is isolated by evaporation of the reaction solvent and purified by trituration of the residue with solvents such as 1-chlorobutane or ethyl ether, and filtration, or by chromatography procedures on silica gel.

Phenylcarbamates and phenylthiocarbamates of Formula VI are prepared by methods described, or obvious modifications thereof, in U.S. Pat. No. 4,443,243, EPA 44,808 or South African Patent Application No. 82/5042.

Equation 4 illustrates the reaction of sulfonamides of Formula Ia with appropriate salts or amines to form corresponding sulfonamides of Formula Ib. ##STR13## wherein P is ##STR14## Alk, R and R.sub.1 are as previously defined; M is Na.sup.+ or K.sup.+ ;

Ta is CN, SCN, N.sub.3, C.sub.1 to C.sub.3 alkoxy, C.sub.1 to C.sub.2 thioalkyl, or F;

Tb is NH(C.sub.1 to C.sub.2 alkyl), N(C.sub.1 to C.sub.2 alkyl).sub.2, N(OCH.sub.3)CH.sub.3, or ##STR15## or 4; and Tc is Ta or Tb.

The reaction of Equation 4 is effected by reacting Ia with at least one molar equivalent of salt M-Ta (at least two molar equivalents when Ta is an alkoxide ox mercaptide) in an inert solvent such as acetone, methyl ethyl ketone, tetrahydrofuran, dioxane, methanol, dimethylformamide (DMF), dimethylsulfone or dimethylsulfoxide. The reaction is carried out at about 20.degree. to 140.degree. C. for 1 to 24 hours, and optionally in the presence of a phase transfer catalyst such as a crown ether. Products Ib (Tc is Ta) are isolated by addition of water, acidification if Ta is alkoxide or mercaptide, and filtration. Alternatively, the aqueous suspension is extracted with a solvent such as methylene chloride, dried and the solvent evaporated to yield crude Ib. Product Ib can be purified further by trituration with a solvent such as 1-chlorobutane, ethyl acetate or diethyl ether, and filtration, or by chromatography procedures on silica gel. Similarly, products Ib (Tc is Tb) can be prepared by reacting Ia with amines, H-Tb, preferably an excess of about 2 to 20 mole equivalents, in an inert solvent such as tetrahydrofuran, p-dioxane, methanol, methylene chloride or DMF. The reactions are carried out at about 0.degree. C. to 100.degree. C. for 1 to 24 hours. Work-up is as described above.

In anlogous manner, other compounds of Formula I can be prepared using procedures described in Equation 4, from appropriate corresponding compounds of Formula I, wherein J is J.sub.2 to J.sub.13 and Q.sup.1 or Q.sup.2 is C(Cl).dbd.NOAlk.

As illustrated in Equation 5, the intermediate sulfonamides of Formula II are conveniently prepared by amination of the corresponding sulfonyl chlorides with anhydrous ammonia or aqueous ammonium hydroxide by general methods known in the art, e.g., Crossley et al., J. Am. Chem. Soc., 60, pages 2223 to 2224 (1938); Pailer, Monatsh, 92, pages 677 to 683 (1961); and U.S. Pat. No. 4,511,392. ##STR16##

As illustrated in Equation 6, sulfonamides of Formula II can also be prepared by deprotection of t-butylsulfonamides of Formula VIII. ##STR17##

The reaction of Equation 6 is conveniently carried out in excess trifluoroacetic acid (TFA) according to the procedure of Catt et al., J. Org. Chem., 39, pages 566 to 568 (1974), or with polyphosphoric acid (PPA) according to procedures of Lomardino, J. Org. Chem., 36, pages 1843 to 1845 (1971). Alternatively, t-butylsulfonamide VIII can be treated with a catalytic amount of p-toluene sulfonic acid (p-TSA) in a solvent such as toluene or xylenes at reflux temperatures for 1 to 24 hours to yield II:

Intermediate sulfonyl chlorides of Formula VIIa are preferably prepared by oxidative-chlorination of an appropriate thioether of Formula IX, as shown below in Equation 7. ##STR18## wherein J is as previously defined, E is a single bond, and R.sub.4 is C.sub.2 to C.sub.3 alkyl or benzyl.

The reaction of Equation 7 is carried out by contacting a suspension of thioether IX in a solvent such as acetic or propionic acid in the presence of at least 2.5 equivalents of water and 3.0 equivalents of chlorine at about -20.degree. to 30.degree. C. for 0.2 to 5 hours. The reaction mixture is poured into ice-water and the product is isolated by filtration or extraction with a solvent such as methylene chloride. The extraction product is optionally washed with aqueous sodium bicarbonate until neutral or slightly basic to litmus, then dried, and the solvent is evaporated to yield a product sufficiently pure to be carried directly on to the next step.

Alternatively, reaction of thioether IX, wherein R.sub.4 is benzyl or hydrogen, with a hypochlorite solution, i.e., NaOCl, can provide sulfonyl chloride VIIa. For additional details, see analogous reactions in South African Patent Application No. 84/8845 and 84/8844. Mercaptans or thioethers can also be transformed to sulfonyl fluorides by reaction with chlorine and potassium hydrogen difluoride, which on further reaction with ammonia or ammonium hydroxide can provide sulfonamides; see, e.g., Brown et al., J. Chem. Soc. Perkins Trans I, pages 522 to 527 (1972).

Sulfonyl chlorides, VIIa, can also be prepared by diazotization reactions, as illustrated in Equation 8. ##STR19##

The amine hydrochloride salt is diazotized with an alkylnitrite in an organic solvent, such as acetonitrile or acetone, and the resulting diazonium salt is reacted with sulfur dioxide and cupric chloride to yield VIIa. Doyle, J. Org. Chem., 42, pages 2426 to 2431 (1977) and ibid, pages 2431 to 2436, describe conditions for analogous reactions. Alternatively, sulfonyl chlorides VIIa can be prepared by aqueous diazotization; for additional details, see EPA 83,975 and 85,476. Aromatic amines of Formual X can be prepared from the corresponding nitro compounds by various known reduction procedures, e.g., Preparative Organic Chemistry, 4 Ed., pages 557 to 563, John Wiley and Sons, New York and London, Hilgetag et al., Eds., and EPA 207,894.

Sulfonyl chlorides of Formula VIIb can be prepared from compounds of Formula XI as shown in Equation 9 and described in U.S. Pat. No. 4,420,325. ##STR20## wherein J is as previously defined and [X] is a suitable halogenating agent, such as N-bromosuccinimide.

Thioethers of Formula IX are important intermediates for preparing compounds of this invention and can be prepared by a variety of general methods known in the art. Several such procedures are described below in Equations 10 through 15.

Equation 10 illustrates the preparation of thioethers of Formula IXa, containing an alpha-chlorooxime moiety, from carboxylic acids of Formula XII. Subsequent reaction of IXa with appropriate salts, M-Ta, or amines, H-Tb, provides thioethers of Formula IXb. ##STR21## wherein R.sub.1, R.sub.4, Alk, M, Ta, Tb and Tc are as previously defined; and [X] is as defined below.

In Equation 10a, carboxylic acids XII are converted to acid chlorides which in turn are converted to isolatable N-alkoxyamides by known methods. Subsequent reaction of the amides with suitable halogenating agents, [X], provides compounds of Formula IXa. Suitable halogenating agents include phosphorous pentachloride or phosphorous pentabromide in an inert solvent such as benzene or chloroform at about 5.degree. to 40.degree. C. for 1 to 24 hours; or phosgene, preferably, or thionyl chloride and a catalytic amount of DMF in an inert solvent such as methylene chloride, benzene or chlorobenzene at about 10.degree. to 130.degree. C. for 0.5 to 24 hours; or more preferably equimolar amounts of triphenylphosphine and carbon tetrachloride (or carbon tetrabromide) in an inert solvent such as acetonitrile at about 0.degree. C. to 80.degree. C. for 1 to 24 hours. Compounds of Formula IXa are isolated by evaporation of reaction media under vacuum and can be purified by optionally treatment with water followed by chromatography procedures on silica gel.

The reactions of Equation 10b are carried out by the general procedures described in Equation 4.

Equation 11 illustrates the preparation of thioethers of Formula IXc, containing an alpha-cyanooxime moiety, from corresponding aldehydes of Formula XIII. ##STR22## wherein R.sub.1, R.sub.4, M and Alk are as previously defined.

The reactions (1) to (4) of Equation 11 are carried out by generally known methods, to provide uncapped oximes of Formula IXc, wherein Alk is H. Subsequent reaction of the uncapped oximes by generally known methods with a suitable base and reagents, M-Alk, in an inert solvent provides capped oximes IXc. Suitable bases and solvents include potassium tert-butoxide in DMF or sodium methoxide in methanol. Reactions (4) and (5) of Equation 11 are further illustrated in Example 7.

In an analogous manner to reactions described in Equations 10 and 11, other thioethers of Formula IX can be prepared, wherein J is J.sub.2 to J.sub.3, by carrying out reactions on appropriate corresponding carboxylic acids or aldehydes.

Equation 12 illustrates the preparation of aldooximes and ketooximes of Formula IXd. ##STR23## wherein R.sub.2, R.sub.4 and Alk are as previously defined;

T.sub.d is C.sub.1 to C.sub.3 alkyl, optionally substituted with OCH.sub.3 or SCH.sub.3 ; or cyclopropyl;

In Equation 12a, 2-fluoropyridine XIV is metallated with lithium diisopropyl amide (LDA) according to the procedure of Gungor, et al., J.Organomet.Chem., 215, pages 139 to 150 (1981), followed by treatment with an acid chloride or a N,N-dimethylamide (or carbon dioxide and H.sub.3 O) by known methods to yield corresponding ketones or aldehydes (or carboxylic acids). In Equation 12b, reaction of halopyridine XV with an appropriate mercaptide in a solvent such as DMF yields the corresponding thioethers, which on reaction with an alkoxyamine by known methods yields compounds of Formula IXd. U.S. Pat. No. 4,456,469 discloses analogous halopyridine-mercaptide reactions.

Also, by known methods, aldo or keto-thioelhers in Equation 12b can be reacted with hydroxylamine followed by a suitable base and an alkylating reagent, M-Alk, to provide capped oximes Ixd. Suitable bases and solvents are described in Equation 11. For details on the reaction of trifluoromethyl ketones with hydroxylamine see, for example, Rosenfeld, U.S. Pat. No. 3,748,361 and R. L. Salvador et al., J Med. Chem., 15, pages 646 to 650 (1972).

Oximes of Formula IXd, wherein Te' is CH.sub.2 CN, can be prepared in a two-step procedure from an appropriate 2-benzylthio-3-pyridyl-carboxylate ester using generally known methods. Thus, reaction of the ester with a suitable base such as sodium hydride and acetonitrile in an inert solvent such as tetrahydrofuran can provide the corresponding 3-ketoacetonitrile, which on subsequent reaction with an appropriate alkoxyamine, or more preferably, its hydrochloride salt, in an inert solvent such as methanol or DMF can provide IXd (Te' is CH.sub.2 CN).

Pyridyl alkyl ketones described in Equations 12a and 12b can also be prepared by reaction of appropriate pyridyl acid chlorides with alkyl Grignard reagents. For details see, for example, Japanese Patent Application No. 60-253,531.

Marsais, et al., J.Orgmet.Chem., 216, pages 139 to 147 (1981) describes the preparation of 3,4 and 2,3-disubstituted pyridines by reacting 3-chloropyridine with, respectively, lithium dialkylamides in tetrahydrofuran or butyl lithium in diethyl ether. By reacting such lithium intermediates with reagents described in Equation 12a followed by Equation 12b, the corresponding 3,4- and 2,3- isomers of IXd can be obtained.

For further details pertaining to the synthesis of pyridines, see Beritmaier, et al., Tetrahedron, 26, 5907 (1970); Blank, et al., J.Med.Chem., 17, pages 1065 to 1071 (1974); Mallet, et al., Tetrahedron, 41, 3433 (1985); and Delarge, et al., Annales Pharm.France, 36, 369 (1978); and R. L. Salvador et al., Tetrahedron, 27, pages 1221 to 1226 (1971). The N-oxidation of pyridine sulfonamides of Formula II, wherein J is J-6 to J-9, is carried out according to known methods for the oxidation of pyridine compounds.

Equations 13 and 14 illustrate the preparation of thiophene carboxylic acids of Formula IXe and IXf. The acids can be used as intermediates for preparing compounds analogous to those described in Equation 10. Also, reduction of the acids or their esters can provide methyl alcohols for analogous reactions described in Equation 11. ##STR24##

In Equations 13 and 14, metal-halogen exchange or metallation with carbon dioxide or a disulfide by known methods provides carboxylic acids IXe and IXf. Starting with 3,4- dibromo-thiophene, and carrying out the reactions of Equation 13, can provide the 3,4- substituted isomer of acid IXe.

Chemical compatibility of the wide variety of reactions, reactants and reaction conditions described throughout this disclosure with respect to J, R.sub.1 to R.sub.3, Q.sub.1 and Q.sub.2 must be evaluated and judicious choices made; one skilled in the art, having this disclosure before him, will be able to readily make such evaluations and choices without undue difficulty. In addition, incompatibility can readily be avoided in certain instances by suitable selection of a protecting group as will be obvious to one skilled in the art. For a compilation of references describing the wide variety of such protecting groups available, see Greene et al., "Protective Groups in Organic Synthesis", John Wiley and Sons, Inc., New York, 1981.

The heterocyclic amines of Formula V in Equation 2 above can be prepared by methods known in the literature, or simple modifications thereof, by those skilled in the art. For instance, EPA 84,224 and Braker et al., J. Chem. Soc., 69, 3072 (1947), describe methods for preparing aminopyridines and triazines substituted by acetal groups such as dialkoxymethyl or 1,3-dioxolan-2-yl, among other groups. Also, South African Patent Application Nos. 82/5045 and 82/5671 describe methods for preparing aminopyrimidines and triazines substituted by haloalkyl or haloalkylthio groups such as OCH.sub.2 CH.sub.2 F, OCH.sub.2 CF.sub.3, SCF.sub.2 H, and OCF.sub.2 H. South African Patent Application No. 83/7434 describes methods for the synthesis of cyclopropylpyrimidines and triazines substituted by such groups as alkyl, haloalkyl, alkoxy, haloalkoxy, alkylamino, dialkylamino or alkoxyalkyl.

The 5,6-dihydrofuro[2,3-d]pyrimidine-2-amines, the cyclopenta[d]pyrimidines-2-amines (V, A is A-2) and the 6,7-dihydro-5H-pyrano[2,3-d]pyrimidin-2-amines (V, A is A-3) can be prepared as described in EPA 15,683. The furo[2,3-d]pyrimidin-2-amines (V, A is A-4) are described in EPA 46,677. Compounds of Formula V, where A is A-7, are described in EPA 125,864.

Compounds of Formula V, where A is A-5, are described in EPA 73,562. Compounds of Formula V where A is A-6, are described in EPA 94,260.

In addition, general methods for preparing aminopyrimidines and triazines have been reviewed in the following publications: "The Chemistry of Heterocyclic Compounds", a series published by Interscience Publ., New York and London; "Pyrimidines", Vol. 16 of the same series by Brown; "s-Triazines and Derivatives", Vol. 13 of the same series by Smolin et al.; U.S. Pat. No. 3,154,547; and Huffman et al., J. Org. Chem., 28, pages 1812 to 1816 (1963), which describes the synthesis of triazines.

Agriculturally suitable salts of compounds of Formula I are also useful herbicides and can be prepared in a number of ways known to the art. For example, metal salts can be made by contacting compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide, or carbonate). Quaternary amine salts can be made by similar techniques.

Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contact of an aqueous solution of a salt of a compound of Formula I (e.g., alkali or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water and can be separated by filtration.

Exchange can also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble, e.g., a potassium, sodium or calcium salt.

Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like.

Using the techniques described in Equations 1 through 18 and Examples 5, 6 and 9, or simple modifications thereof, the following compounds in Tables 1 through 9 can be made.

Useful formulations of the compbunds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used as spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of these carriers: (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid inert diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide", 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0.degree. C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and Pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pages 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1963, pages 8-57ff.

In the following examples, all parts are by weight unless otherwise indicated.

The surfactant is sprayed upon the active ingredient in a blender and the mixture sifted through a U.S.S. No. 40 sieve (0.42 mm openings) prior to packaging. The concentrate may be formulated further for practical use.

The ingredients are thoroughly blended. The liquid surfactant is added by spraying upon the solid ingredients in the blender. After grinding in a hammer mill to produce particles essentially all below 100 microns, the material is reblended and sifted through a U.S.S. No. 50 sieve (0.3 mm opening) and packaged.

The ingredients are blended and ground together in a sand mill to produce particles essentially all under 5 microns in size.

The ingredients are combined and ground together in a sand mill to produce particles essentially all below 3 microns. The product can be used directly, extended with oils, or emulsified in water.

The ingredients are ground together in a sand mill until the solid particles have been reduced to under about 5 microns. The resulting thick suspension may be applied directly, but preferably after being extended with oils or emulsified in water.

The ingredients are ground together in a ball or roller mill until the solid particles have been reduced to diameters under 10 microns.

The ingredients are thoroughly blended, passed through an air mill, to produce an average particle size under 15 microns, reblended, and sifted through a U.S.S. No. 50 sieve (0.3 mm opening) before packaging.

All compounds of the invention may be formulated in the same manner.

The ingredients are blended in a rotating mixer and water sprayed on to accomplish granulation. When most of the material has reached the desired range of 1.0 to 0.42 cm (U.S.S. No. 18 to 40 sieves), the granules are removed, dried, and screened. Oversized material is crushed to produce additional material in the desired range. These granules contain % active ingredient.

The ingredients are blended, coarsely hammer-milled and then air milled to produce particles of active essentially all below 10 microns in diameter. The product is reblended before packaging.

The ingredients are blended, hammer-milled and then moistened with about 12% water. The mixture is extruded as cylinders about 3 mm diameter which are cut to produce pellets about 3 mm long. These may be used directly after drying, or the dried pellets may be crushed to pass a U.S.S. No. 20 sieve (0.84 mm openings). The granules held on a U.S.S. No. 40 sieve (0.42 mm openings) may be packaged for use and the fines recycled.

The ingredients are blended and then ground in a hammer-mill to produce particles with an average particle size less than 25 microns in diameter. The material is reblended and sifted through a U.S.S. No. 50 sieve (0.3 mm opening) before being packaged.

The ingredients are blended and ground in a hammer-mill to produce a high strength concentrate essentially all passing a U.S.S. No. 50 sieve (0.3 mm opening). This material may then be formuated in a variety of ways.

Test results indicate that the compounds of the present invention are highly active preemergent or postemergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum preand/or postemergence weed control in areas where complete control of all vegetation is desired, such as around storage tanks, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Some of the compounds have utility for selective weed control in crops such as rice, wheat, barley, corn, sorghum, soybeans and cotton. Alternatively, the subject compounds are useful to modify plant growth.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as plant growth modifiers or as herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.001 to 20 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for plant growth modification or for situations where only short-term persistence is required, such as a herbicide for fallow land.

The compounds of the invention may be used in combination with any other commercial herbicide, representative examples of which are those of the sulfonylurea, triazine, triazole, uracil, urea, amide, diphenyl ether, carbamate, imidazolinone, cineole and bipyridylium types. A partial listing follows:

C=chlorosis/necrosis

B=burn

D=defoliation

E=emergence inhibition

G=growth retardation

H=formative effect

U=unusual pigmentation

X=axillary stimulation

S=albinism

6Y=abscised buds or flowers.

The third pot was planted with wheat (Triticum aestivum), barley (Hordeum vulgare), wild buckwheat (Polygonum convolvulus), cheatgrass (Bromus secalinus) or downy brome (Bromus tectorum), sugarbeet (Beta vulgaris), wild oat (Avena fatua), common chickweed (Stellaria media) or field violet (Viola arvensis), blackgrass (Alopecurus myosuroides), and rape (Brassica napus). The plants were grown for approximately fourteen days, then sprayed postemergence with the chemicals dissolved in a nonphytotoxic solvent.

Three round pans (25 cm diameter by 12.5 cm deep) were filled with Sassafras sandy loam soil. One pan was planted with nutsedge tubers, crabgrass, sicklepod, jimsonweed, velvetleaf, lambsquarters, rice, and teaweed. The second pot was planted with green foxtail, cocklebur, morningglory, cotton, johnsongrass, barnyardgrass, corn, soybean, and giant foxtail. The third pot was planted with wheat, barley, wild buckwheat, cheatgrass or downy brome, sugarbeet, wild oat, chickweed or field violet, blackgrass, and rape. The three pans were sprayed preemergence with the chemicals dissolved in a non-phytotoxic solvent.

Treated plants and controls were maintained in the greenhouse for approximately 24 days, then all rated plants were compared to controls and visually rated for plant response.

Response ratings are based on a scale of 0 to 100 where 0=no effect, and 100=complete control. A dash (-) response means no test.

Response ratings are contained in Table B.

Postemergence plantings were grown in Sassafras sandy loam soil. Corn and soybeans were grown in separate 25 cm diameter containers. Sorghum and the seven grass weed species were grown in two 18 cm diameter containers, 4 species per container. The seven broadleaf weed species were also grown in two 18 cm diameter containers, 4 species in one container, 3 species in the second container. One additional planting of corn in an 18 cm diameter container was made. The soil surface of this additional container of corn was covered with the absorbent, perlite, before spray treatment so that test chemicals would enter the plant only via the foliage. The plants were grown 10-21 days, dependent upon the species and then sprayed postemergence with the test chemicals dissolved in a nonphytotoxic solvent.

Preemergence plantings were grown in fertilized Tama silt loam soil. These plantings are identical to those described in the postemergence section, with the exception of the corn planting having perlite covering the soil surface. These plantings were made the day of or the day before spraying the test chemicals dissolved in a nonphytotoxic solvent.

Treated plants and controls were maintained in the greenhouse for 2 to 4 weeks. Visual planting response ratings were made on a percentage scale of 0 to 100 in comprison with a control where 0=no injury, and 100=death. Response ratings are contained in Table C.

Weed species were planted 3 or 4 per 15-cm diameter pot in Sassafras sandy loam (pH 6.8; 1% OM). Cotton was planted separately in the same sized pot. Postemergence plantings were made 12-16 days prior to treating so plants were in the 2- to 3-leaf stage (5-12 cm tall). Preemergence plantings were made the day before treating. Compounds were sprayed in a suitable nonphytotoxic solvent at 374 l/ha, then after 3 weeks of growth in a greenhouse, plant responses were visually rated on a percent scale where 0=no injury and 100=plant death. The following species were included:

The results are shown in Table D.

Sixteen-cm-diameter Airlite plastic pots were partially filled with Tama silt loam soil and the soil saturated with water. Japonica and Indica rice seedlings at the 2.0 to 2.5 leaf stage were transplanted into 1/3 of the pots. Into another third of the pots were transplanted seedling or sprouted tubers of water Plantain (Alisma trivale), Scripus (Scirpus paludosus), Cyperus (Cyperus esculentus), and arrowhead (Sagittaria spp.). The remaining pots were planted with barnyardgrass (Echinochloa crus-galli) seeds and sprouted tubers of water chestnut (Eleocharis spp.). These weeds all represent major rice weeds or genera of weeds important in rice. Three to four days after planting, the water level was raised to 3 cm (about 1200 ml/pot) and maintained at this level throughout the test. Chemical treatments were apPlied directly to the paddy water, within 24 hours of raising the water, after being formulated in a nonphytotoxic solvent. The pots were maintained in the greenhouse. Rates of application and plant response ratings made 21 days after treatment are summarized in Table E.

For the postemergence phase of the test, crop and weed species were planted in a Sassafras sandy loam soil (approximately 1% organic matter) one to three weeks before application so that they were present as young plants at the time of treatment. Alterntively, for postemergence tests, plants were grown in a 50:50 mixture of commercially available potting mix and Sassafras soil. Plantings for the preemergence phase were made in a Tama silt loam soil (approximately 3% organic matter) the day before, or the day of treatment. Approximate planting depths were corn and soybeans--3 to 4 cm; morningglory, cocklebur, and nutsedge--2.5 to 3 cm; velvetleaf, sicklepot, and sesbania--2 cm; all other species--0.5 cm.

The test chemicals were dissolved/suspended in a nonphytotoxic solvent in concentrations required to obtain the desired rate of application. The solutions or suspensions were then applied as soil/foliage sprays to the young plants (postemergence phase) and to the soil surfaces of the freshly planted containers (preemergence phase). Application was made utilizing an automatic spray machine at a spray volume of 374 liters per hectare. Immediately after treatment, the containers were transferred to a greenhouse and subsequently watered on a demand basis, taking care not to wet the foliage of the plants in the postemergence phase of the test.

The following species were included in the test:

Visual plant response ratings were made approximately two and four weeks after treatment for the post- and pre-emergence phases, respectively. The ratings were made on a percentage scale of 0 to 200, where 0=no injury, and 100=death of plants. Plant response ratings are summarized in Table F.

The species below were planted.

Two days later, a second series were planted using the following species.

Seven days following the first planting, a third pot was prepared with the following species.

All postemergence plantings were grown in the greenhouse until herbicide application. Preemergence treaments were prepared immediately before herbicide application in the same manner as described for the postemergence treatments. Application of the herbicide was accomplished by first diluting the technical material in a nonphytotoxic solvent and applying over the surface of the plants and soil of all six components using a belt sprayer.

After treatment, all components were removed to the greenhouse where they were maintained for 21 days at temperatures of 19.degree. C. night and 30.degree. C. day with a 16-hour photoperiod and a relative humidity of 45 to 80 percent. At this time, all species were rated using a visual scale of 0 representing no control and 100 representing complete control. Test results are summarized in Table G.
