Herbicidal aryl triazolinones

The invention described in this application pertains to weed control in agriculture, horticulture, and other fields where there is a desire to control unwanted plant growth. More specifically, the present application describes certain herbicidal aryl triazolinones, compositions of them, methods of preparing them, and methods for preventing or destroying undesired plant growth by preemergence or postemergence application of the herbicidal compositions to the locus where control is desired. The present compounds may be used to effectively control a variety of bothh grassy and broadleaf plant species. The present invention is particularly useful in agriculture; a number of the compounds described herein show a selectivity favorable to certain crops at application levels which inhibit the growth of or destroy a variety of weeds.
One aspect of this invention relates to herbicidal compounds of the general formula ##STR2## wherein R.sup.2 is CHF.sub.2 or CH.sub.2 F;
X is bromine, chlorine, or fluorine or haloalkyl (e.g. CF.sub.3);
R.sup.1 may be halogen (e.g. chlorine), alkyl (e.g. of 1 to 5 carbon atoms), haloalkyl (e.g. of 1 to 5 carbon atoms such as difluoromethyl), alkoxyalkyl (e.g. of 2 to 6 carbon atoms such as methoxymethyl), cyanoalkyl (e.g. of 2 to 6 carbon atoms such as cyanomethyl), arylalkyl such as benzyl, alkylthio (e.g. of 1 to 3 carbon atoms such as methylthio) or the corresponding alkylsulfinyl or alkylsulfonyl, or alkylthioalkyl (e.g., of 1 to 3 carbon atoms independently with respect to each alkyl, such as methylthiomethyl) or the corresponding alkylsulfinylalkyl or alkylsulfonylalkyl.
Y is bromine, chlorine, fluorine, methyl, haloalkyl (e.g. FCH.sub.2), a radical of the formula R.sup.8 OCH.sub.2 --, R.sup.8 SCH.sub.2 --, R.sup.8 SOCH.sub.2 -- or R.sup.8 SO.sub.2 CH.sub.2 -- where R.sup.8 is C.sub.1 -C.sub.3 alkyl, C.sub.2 -C.sub.5 alkenyl, or C.sub.3 -C.sub.5 alkynyl (e.g., CH.sub.3 OCH.sub.2 --, CH.sub.3 SCH.sub.2 --, CH.sub.2 .dbd.CHCH.sub.2 OCH.sub.2 --, CH.sub.2 .dbd.CHCH.sub.2 SCH.sub.2 --, CH.tbd.CCH.sub.2 OCH.sub.2 --, or CH.tbd.C--CH.sub.2 SCH.sub.2 --); R.sub.8 may also be phenyl (or phenyl substituted with e.g., halogen, alkyl, haloalkyl; see, e.g. compound 50, below).
R.sup.3 is an alkylene radical (e.g. a lower alkylene such as --CH.sub.2 -- or --CH(CH.sub.3)--) or a haloalkylene radical (e.g. --CHF--) and R.sup.4 is an alkyl radical (e.g. CH.sub.3, C.sub.2 H.sub.5, C.sub.3 H.sub.7, C.sub.4 H.sub.9).
It is preferred that R.sup.1 be methyl and R.sup.2 be CHF.sub.2 and particularly that X be chlorine or (more preferably) fluorine and Y be chlorine.
Some of the compounds described above differ from otherwise similar compounds disclosed in U.S. Pat. No. 4,318,731 in that R.sup.2 of that patent is hydrogen, an alkyl group, or an alkenyl group. It has been found now that the replacement of an alkyl group by a CHF.sub.2 or CH.sub.2 F group yields compounds of much greater herbicidal activity. This is shown, for instance, in Table I below which gives the results of tests of the following two compounds, each applied at the rate of 0.125 kg. per hectare:
A. A compound in which R.sup.2 is CHF.sub.2 (compound No. 5 described below).
B. An otherwise identical compound in which R.sup.2 is C.sub.2 H.sub.5 (compound 62 of the aforesaid U.S. patent).
Representative compounds according to this aspect of the invention are given in Table 2 below.
The herbicidal esters of the aspect of the invention described above may be hydrolyzed to produce the corresponding acids, i.e., to compounds of the foregoing formula in which the substituent para to "X" is --OR.sup.3 COOH (i.e. carboxyalkoxy). I have found that these acids are also effective herbicides, somewhat less potent than the corresponding esters. The acids are also useful as intermediates for the preparation (as by esterification or amide formation) of other herbicidal compounds. The acids may be converted to their salts, such as their sodium, potassium, ammonium, calcium, magnesium, or mono, di or trialkylammonium salts, which may be used as herbicides.
Representative acids and salts are shown in Table 3 below.
In another aspect of this invention it has now been found that compounds of the following formula are effective herbicidal compounds: ##STR3## wherein R.sup.4 is a substituted alkyl group, an alkenyl group (e.g. allyl or methallyl) or an alkynyl group (e.g., propargyl) or a monovalent cyclic group having a ring of 5 or 6 atoms (e.g. an aromatic or heterocyclic or alicyclic ring) whose valence is on a carbon atom of said ring, and Z is O or S. Corresponding compounds in which Z is sulfur and R.sup.4 is unsubstituted alkyl (e.g. of 1-4 carbon atoms) have also been found to be effective herbicides. With respect to R.sup.4, examples of suitable substituents on the alkyl group are:
nitro;
halo (Cl, F, Br);
furyl or tetrahydrofuryl;
acetyl (CH.sub.3 CO);
--CO--N(R.sup.II)(R.sup.III) where --N(R.sup.II)(R.sup.III) is the residue (minus hydrogen) of ammonia or of a primary or secondary amine (e.g. methylamine, dimethylamine or other lower alkylamine);
cyano;
--COOR.sup.IV where R.sup.IV is the residue of an alcohol (such as the residue of a lower alkanol, e.g. a methyl or ethyl radical);
phenyl or substituted phenyl;
alkylamino, dialkylamino or a trialkylammonium salt (such as that shown in compound no. B20 below);
alkoxy, alkylthio, alkylsulfinyl or alkylsulfonyl (in which radicals the alkyl is preferably methyl or other lower alkyl) or phenoxy, phenylthio, phenylsulfinyl, or phenylsulfonyl (in which radicals the phenyl moiety may be substituted or unsubstituted).
When R.sup.4 is alkenyl or alkynyl it may be substituted with one of the foregoing substituents.
For the substituted phenyls mentioned above the substituents may be, for instance, alkyl, haloalkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, halogen, cyano, nitro, hydroxy, amino or alkyl or dialkylamino or carboxyl.
It is preferred that X, Y, R.sup.1 and R.sup.2 be as defined above for Formula I, and particularly that X be chlorine or (more preferably) fluorine, Y be chlorine, R.sup.1 be methyl and R.sup.2 be CHF.sub.2. However, within the broader scope of this aspect of the invention R.sup.2 substituents may be alkyl (e.g. of 1 to 5 carbon atoms), haloalkyl (e.g. of 1 to 5 carbon atoms, such as CHF.sub.2), alkenyl of 2 to 5 carbon atoms (e.g. allyl), alkynyl of 3 to 5 carbon atoms (e.g. propargyl), cyanoalkyl (e.g. CH.sub.2 CN or CH.sub.2 CH.sub.2 CN), thiocyanoalkyl (e.g. CH.sub.2 SCN) or a group of the formula -alkylene-Y.sup.1 -R.sup.5 in which said alkylene group (e.g. --CH.sub.2 --) has 1 to 5 carbon atoms, Y.sup.1 being oxygen or S(O).sub.r in which r is 0 to 2, and R.sup.5 being alkyl (e.g. of 1 to 5 carbon atoms such as methyl), alkenyl of 2 to 5 carbon atoms (e.g. allyl) or alkynyl of 3 to 5 carbon atoms (such as propargyl).
Representative compounds according to this aspect of the invention are shown in Table 4 below.
In still another aspect of this invention it has now been found that compounds of the following formula are effective herbicidal compounds: ##STR4## in which R.sup.3 is an alkylene radical (e.g. --CH.sub.2 -- or --CH(CH.sub.3)--) or a haloalkylene radical (e.g. --CHF--), and ##STR5## is --NH.sub.2 or the residue of a primary or secondary amine or of a sulfonamide. For instance, R.sup.6 and R.sup.7 may be, each, independently, H, alkyl, alkenyl, alkynyl, cycloalkyl, aryl, alkoxy, alkylsulfonyl, haloalkylsulfonyl, cycloalkylsulfonyl, arylsulfonyl (including heteroarylsulfonyl such as thienylsulfonyl), aralkylsulfonyl, aminosulfonyl, dialkylaminosulfonyl, alkylaminosulfonyl, alkenylsulfonyl, phenylalkenylsulfonyl. R.sup.6 may be bicyclic or polycyclic such as benzofuranyl, dihydrobenzofuranyl benzofuransulfonyl, dihydrobenzofuransulfonyl, naphthalenesulfonyl, benzodioxosulfonyl, anthraquinonesulfonyl. Any of R.sup.6, R.sup.7 may carry one or more substituents such as halogen, nitro, amino, alkoxy, alkyl, haloalkoxy, alkenyloxy, haloalkenyloxy, alkoxyalkoxy, alkoxyalkylthio, cyano, aminocarbonyloxy, alkylaminocarbonyloxy or dialkylaminocarbonyloxy, acylamino, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl or hydroxycarbonyl (but when one of R.sup.6, R.sup.7 is connected to the nitrogen of formula III by an oxygen or sulfur atom, then the other of R.sup.6, R.sup.7 is H or a group connected to that nitrogen by a carbon-nitrogen linkage or a salt-forming group, such as indicated below). R.sup.6 and R.sup.7 may together comprise a divalent group, such as an alkylene or haloalkylene or alkyloxyalkylene group or thioether, or its corresponding sulfine or sulfone, (e.g. such that NR.sup. 6 R.sup.7 together comprise a pyrrolidino, piperidino, morpholino, or thiazolidino ring), any of which may also carry a carboxylic ester or amide substituent. The salt-forming group (e.g. when R.sup.6 is alkylsulfonyl, cycloalkylsulfonyl or arylsulfonyl) may be a metal (e.g. Na, K or Ca) or ammonium (e.g. NH.sub.4 or lower alkyl-substituted ammonium). R.sup.6 and R.sup.7 may comprise a divalent group such that NR.sup.6 R.sup.7 together constitute, for instance, a saccharin ring structure, e.g. ##STR6## which is an active herbicide (such as compound C62 below) and which upon hydrolysis, can lead to other active herbicides such as compounds C58 and C59.
Compound C62 for example is obtainable by reaction of saccharin ##STR7## with the appropriate acid chloride.
In this (Formula III) aspect of the invention, X, Y and R.sup.1 may be as defined above for Formula I, and R.sup.2 may be as defined above for Formula II. It is preferred that R.sup.1 be methyl and R.sup.2 be CHF.sub.2 and particularly that X be chlorine or (more preferably) fluorine and Y be chlorine.
Representative compounds according to this aspect of the invention are shown in Table 5 below.
Still another aspect of this invention relates to herbicidal compounds of the formula ##STR8## where --OR.sup.9 is the residue of an oxime, such as a ketoxime of the formula ##STR9## each alkyl group preferably being lower alkyl such as methyl. X, Y, R.sup.1 and R.sup.2 have the meanings given in connection with Formula I (for X, Y and R.sup.1) and Formula II (for R.sup.2). Preferably X is chlorine or (more preferably) fluorine, Y is chlorine, R.sup.1 is methyl and R.sup.2 is CHF.sub.2 ; in some typical compounds of this kind the radical OR.sup.3 COOR.sup.9 is ##STR10## X is fluorine, Y is chlorine, R.sup.1 is methyl and R.sup.2 is CHF.sub.2 ; other typical compounds are identical with those except that Y is Br or CF.sub.3. Compounds of Formula IV may be prepared by reacting the corresponding acid chloride (i.e. the compound in which the substituent at the 5-position of the benzene ring is --OR.sup.3 COCl) with the corresponding oxime in the presence of an acceptor for HCl such as triethylamine or sodium carbonate or sodium hydroxide.
In each aspect of the invention, it is often preferable that any alkyl, alkenyl, alkynyl or alkylene radical have less than 6 carbon atoms.
The compounds of this invention may be prepared by methods generally described in the literature or by methods analogous or similar thereto and within the skill of the art. One type of method starts with an intermediate in which the substituent para to "X" is hydroxyl. For instance, one may use the intermediate described in "Synthetic Process Example 6" of UK patent application No. GB 2 090 250 published July 7, 1982, in which X and Y are Cl, R.sup.1 is CH.sub.3 and R.sup.2 is CHF.sub.2 (the corresponding compound in which R.sup.2 is CH.sub.2 F is made by substituting chlorofluoromethane for the chlorodifluoromethane used in "Synthetic Process Example 1" of that published patent application). The OH group of the intermediate may then be converted to the desired substituent, as by a conventional etherification reaction, e.g., by reacting it with the appropriate bromide in the presence of a known acceptor of HBr such as NaH or a mixture of K.sub.2 CO.sub.3 and NaI.
As illustrated in Examples 2 and 3 below, the synthesis may employ a substituted phenylhydrazine, whose hydrazine portion is then modified to form a triazolinone ring. Such modification (which in Examples 2 and 3 is effected by reaction with pyruvic acid and then with a phosphoryl azide) may also be effected by other techniques, such as by treating the substituted phenylhydrazine with any of the following four types of reagents:
(a) an inner salt of a 3-(1-iminoalkylmercapto)-1-propanesulfonic acid (which may be prepared according to Reid and Schmidt, Ann. Chem. 676, 114 (1964) from 1,3-propanesultone and a thioamide), to form an amidrazone followed by reaction with a source of phosgene, as by the following reaction sequence (which is also illustrated in Example 15 below), ##STR11## in which "Ar" is aromatic as described below.
(b) An imidate ester of the formula ##STR12## to form the corresponding amidrazone (as described, for instance, in the article by Neilson et al "The Chemistry of Amidrazones: Chem. Rev. 70, 151(1970) at page 156), followed by reaction with a source of phosgene, as in (a) above, R.sup.c and R.sup.d being alkyl or other suitable radical.
(c) A compound of the formula ##STR13## (where R.sup.a and R.sup.b are lower alkyl) in the presence of a base according to the following sequence: ##STR14## in which R.sup.1 is as defined above, e.g. methyl;
(d) A haloalkylnitrile (e.g. a fluoroalkyl, fluorochloroalkyl or fluorobromoalkyl nitrile such as ClCF.sub.2 CN, followed by reaction with a source of phosgene, so that the reaction may proceed along the following lines, for instance (and as also illustrated in Example 16 below), to form the aryl 3-haloalkyl triazoline, thus: ##STR15##
In Examples 2 and 3 below the "Ar" portion of the aryl hydrazine (whose hydrazine portion is then modified to form the triazoline ring) has halo substituents at its 2 and 4 positions and an alkoxy group at its 5 position. Instead, in each of the processes illustrated above (and in the process of those Examples 2 and 3), the Ar group may be a phenyl radical or a fluorophenyl (e.g. 2-fluorophenyl) or a nitrophenyl (e.g. 3-nitrophenyl)alkoxyphenyl (e.g. 3-methoxyphenyl) or, most preferably, halonitrophenyl, particularly a fluoronitrophenyl (such as 2-fluoro-5-nitrophenyl) or haloalkoxyphenyl (such as 2-fluoro-5-alkoxyphenyl) and the aryl triazoline may then be treated to (a) alkylate the nitrogen at the 4-position of the triazoline ring (in known manner, e.g. with an alkyl or fluoroalkyl halide, such as with ClCHF.sub.2 to add the preferred--CHF.sub.2 substituent) and (b) to introduce additional substituents onto the aromatic ring, as by halogenation with chlorine or bromine (e.g. by reacting with Cl.sub.2, Br.sub.2 or SO.sub.2 Cl.sub.2). For instance the alkylation of the nitrogen at the 4-position may be effected first, after which the nitro group (if present) may be reduced to an amino group in conventional manner, the amino group may be converted to a hydroxyl group (as by conventional diazotization) and then, preferably after etherifying the OH to form an alkoxy (e.g. methoxy) group, the compound may be halogenated as above to place the halogen substituent or substituents on its benzene ring. The resulting compound may then be modified at the 5-position of the benzene ring to form the herbicidal compounds of this invention. For instance, for making the preferred compounds of the invention in which the benzene ring has a 2-fluoro substituent, the starting material may be 2-fluoro-5-nitrophenylhydrazine, which may be treated as described above to produce successively a series of novel compounds such as 1-(2-fluoro-5-nitrophenyl)-4,5-dihydro-3-methyl-1,2,4-triazol-5(1H)-one, then 1-(2-fluoro-5-nitrophenyl-4,5-dihydro-4-difluoromethyl-3-methyl-1,2,4-triazol-5(1H)-one. These may be converted to the corresponding novel compounds having, at the 5-position of the benzene ring, successively --NH.sub.2, --OH and (preferably) --OCH.sub.3, followed by halogenation to place, for instance, a chloro or bromo substituent at the 4-position of the benzene ring. Instead of alkylating at the 4-position of the ring triazoline at an early stage, e.g. prior to altering the nitro group, this alkylation step may be delayed until after the abovedescribed halogenation of the benzene ring or even until after the conversion of the alkoxy (or other) group at the 5-position of the benzene ring to one of the groups described at that position in Formulas I, II, III and IV (and Tables 2, 3, 4, and 5) above.
Similarly, when the reagent(s) used to react with the aryl hydrazine are such as to produce a triazolinone having a haloalkyl (e.g. CHF.sub.2) group instead of an alkyl group on the carbon at the 3-position of the heterocyclic ring, the series of new compounds will include, successively, (from 2-fluoro-5-nitrophenyl hydrazine) such compounds as 1-(2-fluoro-5-nitrophenyl)-4,5-dihydro-3-difluoromethyl-1,2,4-triazol-5-(1H)-one, then 1-(2-fluoro-5-nitrophenyl)-4,5-dihydro-4-methyl (or difluoromethyl)-3-difluoromethyl-1,2,4-triazol-5(1H)-one. These may be converted to the corresponding novel compounds having, at the 5-position of the benzene ring, successively --NH.sub.2, --OH and (preferably) --OCH.sub.3 followed by halogenation to place, for instance, a chloro or bromo substituent at the 4-position of the benzene ring. When the aryl hydrazine is 3-nitrophenyl hydrazine (instead of 2-fluoro-5-nitrophenylhydrazine) the series of novel compounds will include, successively, such compounds as 1-(3-nitrophenyl)-4,5-dihydro-3-difluoromethyl-1,2,4-triazol-5(1H)-one, then 1-(3-nitrophenyl)-4,5-dihydro-4-methyl (or difluoromethyl)-3-difluoromethyl-1,2,4-triazol-5(1H)-one. These may be converted to the corresponding novel compounds having, at the 3-position of the benzene ring, successively --NH.sub.2, --OH and (preferably) --OCH.sub.3, followed by halogenation to place, for instance, chloro or bromo substituents on the benzene ring.
Example 11 below illustrates a process for making a compound of this invention having a sulfonamide group at the 5-position of the benzene ring by reacting (a) a compound having an oxypropionic acid substituent at that 5-position with (b) an aryl sulfonylisocyanate.
Another method for introducing the sulfonamide group is by reacting (a) a compound having a phenolic OH group at that 5-position with (b) an N-aryl (or alkyl etc.) sulfonylalkanoic acid amide having a reactive leaving substituent (e.g. Br, Cl, mesylate or tosylate) on the alkane portion of the molecule, e.g. ##STR16## Such a reaction can be carried out in the presence of a base (e.g. in acetone in the presence of sodium or potassium carbonate). This method is illustrated in Example 14 below.
The following Examples illustrate the preparation of the compounds of this invention.

After complete addition the mixture was heated at reflux for 1.5 hours then allowed to cool to room temperature for approximately 18 hours. The reaction mixture was decanted from a dark residue in the reaction flask and washed with water. The washed mixture was extracted with a 10% aqueous sodium hydroxide solution. The basic extract was made acidic with concentrated hydrochloric acid to form an oily precipitate. This aqueous phase was decanted from the oily residue and fresh water added to wash the residue. This residue was dissolved in 160 mL of methylene chloride and filtered through a celite pad. The filtrate was dried over anhydrous magnesium sulfate and filtered.

HERBICIDAL ACTIVITY
The plant test species used in demonstrating the herbicidal activity of compounds of this invention include cotton (Gossypium hirsutum var. Stoneville), soybean (Glycine max var. Williams), field corn (Zea mays var. Agway 595S), wheat (Triticum aestivium var. Prodax), rice (Oryza sativa), field bindweed (Convolvulus arvensis), morningglory (Ipomea lacunosa or Ipomea hederacea, velvetleaf (Abutilon theophrasti), barnyardgrass (Echinochloa crus galli), green foxtail (Setaria viridis), and johnsongrass (Sorghum halepense), yellow nutsedge (Cyperus esculentus).
Seeds or tubers of the plant test species were planted in furrows in steam sterilized sandy loam soil contained in disposable fiber flats. A topping soil of equal portions of sand and sandy loam soil was placed uniformly on top of each flat to a depth of approximately 0.5 cm.
The flats for the preemergence test were watered, then drenched with the appropriate amount of a solution of the test compound in a mixture of acetone and water containing a small amount (up to 0.5% v/v) of sorbitan monolaurate emulsifier/solubilizer. The concentration of the test compound in solution was varied to give a range of application rates, generally 8.0 kg/ha and submultiples thereof. The flats were placed in a greenhouse and watered regularly at the soil surface for 21 days at which time phytotoxicity data were recorded.
The flats for the postemergence test were placed in a greenhouse and watered for 8-10 days, then the foilage of the emerged test plants was sprayed with a solution of the test compound in acetone-water containing up to 0.5% sorbitan monolaurate. After spraying, the foilage was kept dry for 24 hours, then watered regularly for 21 days, and phytotoxicity data recorded.
Phytotoxicity data were taken either as percent kill or percent control. Percent control was determined by a method similar to the 0 to 100 rating system disclosed in "Research Methods in Weed Science," 2nd ed., B. Truelove, Ed.; Southern Weed Science Society; Auburn University, Auburn, Ala., 1977. The present rating system ia as follows:

Herbicidal data at selected application rates are given for various compounds of the invention in the tables below. The test compounds are identified in the tables of herbicidal data below by numbers which correspond to those used above.
In the Tables of herbicidal data below:
"kg/ha" is kilograms per hectare,
"% K" is percent kill, and
"% C" is percent control.
For herbicidal application, the active compounds as above defined are formulated into herbicidal compositions by admixture in herbicidally effective amounts with adjuvants and carriers normally employed in the art for facilitating the dispersion of active ingredients for the particular utility desired, recognizing the fact that the formulation and mode of application of a toxicant may affect the activity of the material in a given application. Thus, for agricultural use the present herbicidal compounds may be formulated as granules of relatively large particle size, water-soluble or water-dispersible granules, as powdery dusts, as wettable powders, as emulsifiable concentrates, as solutions or as any of several other known types of formulations, depending on the desired mode of application.
For preemergence application these herbicidal compositions are usually applied either as sprays, dusts, or granules to the areas in which suppression of vegetation is desired. For postemergence control of established plant growth, sprays or dusts are most commonly used. These formulations may contain as little as 0.5% to as much as 95% or more by weight of active ingredient.
Dusts are free flowing admixtures of the active ingredient with finely divided solids such as talc, natural clays, kieselguhr, flours such as walnut shell and cottonseed flours, and other organic and inorganic solids which act as dispersants and carriers for the toxicant; these finely divided solids have an average particle size of less than about 50 microns. A typical dust formulation useful herein is one containing 1.0 part of the herbicidal compound and 99.0 parts of talc.
Wettable powders, also useful formulations for both pre- and postemergence herbicides, are in the form of finely divided particles which disperse readily in water or other dispersant. The wettable powder is ultimately applied to the soil either as a dry dust or as an emulsion in water or other liquid. Typical carriers for wettable powders include Fuller's earth, kaolin clays, silicas, and other highly absorbent, readily wet inorganic diluents. Wettable powders normally are prepared to contain about 5-80% of active ingredient, depending on the absorbency of the carrier, and usually also contain a small amount of a wetting, dispersing or emulsifying agent to facilitate dispersion. For example, a useful wettable powder formulation contains 80.8 parts of the herbicidal compound, 17.9 parts of Palmetto clay, and 1.0 part of sodium lignosulfonate and 0.3 part of sulfonated aliphatic polyester as wetting agents. Frequently, additional wetting agent and/or oil will be added to the tank-mix for postemergence application to facilitate dispersion on the foliage and absorption by the plant.
Other useful formulations for herbicidal applications are emulsifiable concentrates. Emulsifiable concentrates are homogeneous liquid or paste compositions dispersible in water or other dispersant, and may consist entirely of the herbicidal compound and a liquid or solid emulsifying agent, or may also contain a liquid carrier, such as xylene, heavy aromatic naphthas, isophorone, or other non-volatile organic solvent. For herbicidal application these concentrates are dispersed in water or other liquid carrier, and normally applied as a spray to the area to be treated. The percentage by weight of the essential active ingredient may vary according to the manner in which the composition is to be applied, but in general comprises 0.5 to 95% of active ingredient by weight of the herbicidal composition.
Typical wetting, dispersing or emulsifying agents used in agricultural formulations include, for example, the alkyl and alkylaryl sulfonates and sulfates and their sodium salts; polyhydric alcohols; and other types of surface active agents, many of which are available in commerce. The surface active agent, when used, normally comprises 1% to 15% by weight of the herbicidal composition.
Other useful formulations for herbicidal applications include simple solutions of the active ingredient in a dispersant in which it is completely soluble at the desired concentration, such as acetone, alkylated naphthalenes, xylene or other organic solvents. Granular formulations, wherein the toxicant is carried on relatively coarse particles, are of particular utility for aerial distribution or for penetration of cover crop canopy. Pressurized sprays, typically aerosols wherein the active ingredient is dispersed in finely divided form as a result of vaporization of a low boiling dispersant solvent carrier, such as the Freons, may also be used. Water-soluble or water-dispersible granules are also useful formulations for herbicidal application of the present compounds. Such granular formulations are free-flowing, non-dusty, and readily water-soluble or water-miscible. The soluble or dispersible granular formulations described in U.S. Pat. No. 3,920,442, incorporated herein by reference, are useful herein with the present herbicidal compounds.
The active herbicidal compounds of this invention may be formulated and/or applied with insecticides, fungicides, nematicides, plant growth regulators, fertilizers, or other agricultural chemicals and may be used as effective soil sterilants as well as selective herbicides in agriculture. In applying an active compound of this invention, whether formulated alone or with other agricultural chemicals, an effective amount and concentration of the active compound is of course employed; the amount may be as low as, for example, 7 g/ha or lower.
The active herbicidal compounds of this invention may be used in combination with other herbicides, e.g. they may be mixed with, say, an equal or larger amount of a known herbicide such as chloroacetanilide herbicides such as 2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide (alachlor), 2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)-acetamide (metolachlor), and N-chloroacetyl-N-(2,6-diethylphenyl)glycine (diethatyl-ethyl); benzothiadiazinone herbicides such as 3-(1-methylethyl)-(1H)-2,1,3-benzothiadiazin-4-(3H)-one-2,2-dioxide (bentazon); triazine herbicides such as 6-chloro-N-ethyl-N-(1-methylethyl)-1,3,5-triazine-2,4-diamine (atrazine), and 2-[4-chloro-6-(ethylamino)-1,3,5-triazin-2-yl]-amino-2-methylpropanenitrile (cyanazine); dinitrolaniline herbicides such as 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)benzeneamine (trifluralin); and aryl urea herbicides such as N'-(3,4-dichlorophenyl)-N,N-dimethylurea (diuron) and N,N-dimethyl-N'-[3-(trifluoromethyl)phenyl]urea (fluometuron).
