Herbicidal agents

The present invention relates to and has for its objects the provision for particular substituted 4-amino-1,2,4-triazine-5-ones, some of which are known, which possess valuable, especially selective, herbicidal properties, active compositions in the form of mixtures thereof with solid and liquid dispersible carrier vehicles, and methods for their preparation and use, especially for combatting weeds, undesired plants, and the like; with other and further objects of this invention becoming apparent from a study of the within specification and accompanying examples.
It is known that 1,3,5-triazines can be used for the control of weeds (see Belgian Pat. No. 540,590). In this group of active compounds, 2,6-di-(ethylamino)-4-chloro-1,3,5-triazine (A) has attained a considerable practical significance.
It has now been found, in accordance with the present invention, that the particular 4-amino-1,2,3-triazine-5-ones having the formula ##EQU1## in which
R is selected from the group consisting of alipphatic having 1-18 carbon atoms, cycloaliphatic having 5-10 ring carbon atoms, araliphatic having 6-10 ring carbon atoms in the corresponding aryl moiety and 1-4 carbon atoms in the aliphatic moiety, aryl having 6-10 ring carbon atoms, heterocyclic having 5-6 ring members with at least one hetero linking atom selected from the group consisting of O, N, S and mixtures of such hetero atoms, heterocyclic-lower alkyl in which the heterocyclic moiety has 5-6 ring members with at least one hetero linking atom selected from the group consisting of O, N, S and mixtures of such hetero atoms, and such aliphatic, cycloaliphatic, araliphatic, aryl, heterocyclic and heterocyclic-lower alkyl, respectively, which is substituted with at least one substituent selected from the group consisting of halo, nitro, carbo lower alkoxy, lower alkyl, lower alkoxy, aryloxy having 6-10 ring carbon atoms, lower alkylmercapto, arylmercapto having 6-10 ring carbon atoms in the aryl moiety, and mixtures of such substituents;
R.sub.1 and R.sub.2 each respectively is selected from the group consisting of hydrogen, alkyl having 1-12 carbon atoms, alkanoyl having 1-6 carbon atoms, and such alkyl and alkanoyl, respectively, which is substituted with at least one substituent selected from the group consisting of cyano, hydroxy, halo, and mixtures of such substituents,
with the proviso that R.sub.1 and R.sub.2 when taken together represent alkylidene having 1-12 carbon atoms, cycloalkylidene having 5-8 ring carbon atoms, and such alkylidene and cycloalkylidene, respectively, which is substituted with at least one substituent selected from the group consisting of cycloalkyl having 5-8 ring carbon atoms, aryl having 6-10 ring carbon atoms, haloaryl having 6-10 ring carbon atoms, lower alkyl aryl having 6-10 ring carbon atoms in the aryl moiety, lower alkoxy aryl having 6-10 ring carbon atoms in the aryl moiety, nitroaryl having 6-10 ring carbon atoms, halo-nitroaryl having 6-10 ring carbon atoms, aryl-lower alkenyl having 6-10 ring carbon atoms in the aryl moiety, heterocyclic having 5-6 ring members with at least one hetero linking atom selected from the group consisting of O, N, S and mixtures of such hetero atoms, nitro-heterocyclic having 5-6 ring members with at least one hetero linking atom selected from the group consisting of O, N, S and mixtures of such hetero atoms, and mixtures of such substituents, and
with the further proviso that R.sub.1 and R.sub.2 when taken together with the adjacent N atom represent N-containing heterocyclic having 5-6 ring member;
Y is selected from the group consisting of O, S and ##EQU2## and
R.sub.3 and R.sub.4 each respectively is selected from the group consisting of hydrogen, aliphatic having 1-18 carbon atoms, cycloaliphatic having 5-8 ring carbon atoms, araliphatic having 6-10 ring carbon atoms in the corresponding aryl moiety and 1-4 carbon atoms in the aliphatic moiety, aryl having 6-10 ring carbon atoms, and such aliphatic, cycloaliphatic, araliphatic and aryl, respectively, which is substituted with at least one substituent selected from the group consisting of halo, amino, lower alkyl substituted amino, nitro, lower alkyl, lower alkoxy, lower alkylmercapto, aryloxy having 6-10 ring carbon atoms, haloarylmercapto having 6-10 ring carbon atoms, and mixtures of such substituents,
with the proviso that R.sub.3 and R.sub.4 when taken together with the adjacent N atom represent N-containing heterocyclic having 5-6 ring members; and
with the further proviso that when Y is O then R.sub.3 may also be lower alkanoyl;
exhibit strong herbicidal properties.
It is very surprising that the particular active compounds usable according to the present invention not only show a stronger herbicidal activity than the known triazines in pre-emergence application but also show a good herbicidal activity when used according to the post-emergence method. Apart from this, the instant compounds also show marked selective herbicidal properties (see Examples 1 and 2 hereinbelow).

The instant new triazinones can be prepared according to the customary methods in the same manner as the known triazinones [see for example Berichte 97, 2173-2178 (1964)].
Advantageously, the instant triazinones influence plant growth and can be used as defoliants, desiccants or herbicides and in particular as weed-killers.
By defoliants and desiccants are meant the customary harvest auxiliaries which are used for removing the leaves from and for drying out the green portions of plants before bringing in the harvest.
By weeds are meant in the widest sense all plants which grow in places where they are undesired.
The instant triazinones can be used as total herbicides for the destruction of weeds, and also as selective herbicides for the destruction of weeds in connection with the cultivation of specific agricultural crops. Whether the instant triazinones act as total herbicides or as selective herbicides depends largely on the concentration thereof which is used as the artisan aware of the present invention will appreciate. Examples of crops for which the triazinones of the instant invention are suitable are cereals (such as oats, barley, rice, maize and in particular wheat), cotton, carrots, snap beans, peas, potatoes, beets, and the like.
As weeds which can be destroyed in accordance with the present invention, there may be mentioned as illustrative examples: dicotyledons, such as mustard (Sinapis), cross (Lepidium), cleaver (Galium), common chickweed (Stellaria), camomile (Matricaria), smallflower Galinsoga (Galinsoga), fathen (Chenopodium), burning nettle (Urtica), groundsel (Senecio); monocotyledons, such as timothy (Phleum), meadow grass (Poa), fescue grass (Festuca), goosegrass (Eleusine), foxtail (Setaria), ryegrass (Lolium), brome grass (Bromus), barnyard grass (Echinochloa), and the like.
The active compounds according to the instant invention can be utilized, if desired, in the form of the usual formulations or compositions with dispersible carrier vehicles, such as solutions, emulsions, suspensions, emulsifiable concentrates, spray powders, pastes, soluble powders, dusting agents, granulates, etc. These are prepared in known manner, for instance by extending the active agents with dispersible liquid diluent carriers and/or dispersible solid carriers optionally with the use of carrier vehicle assistants, e.g., surface-active agents, including emulsifying agents and/or dispersing agents, whereby for example, in the case where water is used as diluent, organic solvents may be added as auxiliary solvents (see Agricultural Chemicals, March 1960, pp. 35-38). The following may be chiefly considered for use as carrier vehicles for this purpose: dispersible liquid diluent carriers, such as aromatic hydrocarbons (for instance, benzene, toluene, xylene, etc.), halogenated, especially chlorinated, aromatic hydrocarbons (for instance, chlorobenzenes), paraffins (for instance, petroleum fractions), chlorinated aliphatic hydrocarbons (for instance, methylene chloride, etc.), alcohols (for instance, methanol, ethanol, propanol, butanol, etc.), ethers, etheralcohols (for instance, glycol monomethyl ether, etc.), amines (for instance, ethanolamine, etc.), amides (for instance dimethyl formamide, etc.), sulfoxides (for instance, dimethyl sulfoxide, etc.), ketones (for instance, acetone, etc.), and water; as well as dispersible finely divided solid carriers, such as ground natural minerals (for instance, kaolins, alumina, silica, chalk, i.e., calcium carbonate, talc, kieselguhr, etc.), and ground synthetic minerals (for instance, highly dispersed silicic acid, silicates, e.g., alkali silicates, etc.); whereas the following may be chiefly considered for use as carrier vehicle assistants, e.g., surface-active agents, for this purpose: emulsifying agents, such as nonionic and anionic emulsifying agents (for instance, polyethylene oxide esters of fatty acids, polyethylene oxide ethers of fatty alcohols, alkyl sulfonates, aryl sulfonates, etc., and especially alkyl arylpolyglycol ethers, magnesium stearate, sodium oleate, etc.); and dispersing agents, such as lignin, sulfite waste liquors, methyl cellulose, etc.
As will be appreciated by the artisan, the active compounds according to the instant invention may be present in such formulations or compositions in the form of mixtures with one another and with other known active substances such as for example known herbicides including ureas, other triazines, uracils, aminotriazole, phenoxy carboxylic acids, benzoic acid, picolinic acid, and the like, if desired.
The substances according to the invention may be employed, therefore, by themselves as the artisan will appreciate, in the form of their compositions with solid or liquid dispersible carrier vehicles or other known compatible active agents, or in the form of particular dosage preparations for specific application made therefrom, such as solutions, emulsions, suspensions, powders, pastes, and granulates which are thus ready for use.
As concerns commercially marketed preparations, these generally contemplate carrier composition mixtures in which the active compound is present in an amount substantially between about 0.1 and 95% by weight, and preferably 0.5 and 90% by weight, of the mixture, whereas carrier composition mixtures suitable for direct application or field application generally contemplate those in which the active compound is present in an amount substantially between about 0.001 and 1.0%, preferably 0.005 and 0.5%, by weight of the mixture. Thus, the present invention contemplates over-all compositions which comprise mixtures of a dispersible carrier vehicle such as a dispersible carrier solid, or a dispersible carrier liquid preferably including a carrier vehicle assistant, e.g., a surface-active agent, such as an emulsifying agent and/or a dispersing agent, and an amount of the active compound which is effective for the purpose in question and which is generally between about 0.001 and 95% by weight of the mixture. Specifically, the active compound may be applied to a surface area, such as in pre-emergence use, in concentrations substantially between about 0.5 and 20 kg per hectare, preferably between about 1 and 10 kg per hectare, although it will be appreciated that in connection with the pre-emergence use of the instant compounds, as well as the post-emergence use thereof, the concentration may be varied within a fairly wide range. However, generally the post-emergance range of concentration will be between about 0.001 and 95%, preferably between about 0.005 and 95%, by weight of the mixture as aforesaid, while the pre-emergence range will be between about 0.5 and 20, preferably between about 1 and 10, kg per hectare, as aforesaid.
Furthermore, the present invention contemplates methods of selectively controlling or combatting undesired plants, e.g., weeds and the like, which comprise applying to at least one of (a) such weeds and (b) their habitat, a herbicidally effective amount of the particular active compound of the invention alone or together with a carrier vehicle as noted above. The instant formulations or compositions are applied in the usual manner, for example, by spraying, atomizing, scattering, dusting, watering, sprinkling, dispersing, and the like, whether for pre-emergence application to the soil or post-emergence application to the weeds.

The following Examples are given for the purpose of illustrating, without limiting, the utility of the instant invention.
EXAMPLE 1
Pre-emergence testSolvent: 5 parts by weight acetoneEmulsifier: 1 part by weight benzyloxypolyglycol ether
To produce a suitable preparation of the particular active compound, 1 part by weight of such active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is then added and the resulting concentrate is thereafter diluted with water to the desired final concentration.
Seeds of the test plants are sown in normal soil and, after 24 hours, watered with the preparation of the given active compound. It is expedient to keep constant the amount of water per unit area. The concentration of the particular active compound in the preparation is of no importance, only the amount of active compound applied per unit area being decisive. After three weeks, the degree of damage to the test plants is determined and characterized by the values 0-5, which have the following meaning:
0 no effect1 slight damage or delay in growth2 marked damage or inhibition of growth3 heavy damage and only deficient development or only 50% emerged4 plants partially destroyed after germination or only 25% emerged5 plants completely dead or not emerged.
The particular active compounds, the amounts applied and the results obtained can be seen from the following Table 1:

b. when Y is S, and R.sub.1, R.sub.2 and R.sub.3 are the same as defined under (a) immediately above,
R is the same as defined under (a) immediately above, with the proviso that when R is aliphatic in accordance with (i) above, said aliphatic always has at least 2, or at least 3, or at least 4, or at least 5, or at least 6, or more, and up to 18 carbon atoms and preferably has 2-6, 3-6, 4-6, or 5-6 and up to 18 carbon atoms, and with the further proviso that when R is aryl in accordance with (iv) above, such aryl is always substituted aryl which is substituted in accordance with (vi) above;

d. when Y is S, and R and R.sub.3 are the same as defined under (a) immediately above,
R.sub.1 and R.sub.2 each respectively is the same as defined under (viii), (ix) and (x) above, as the case may be, with the proviso that R.sub.1 and R.sub.2 when taken together represent alkylidene or cycloalkylidene as defined under (xi) through (xiii) above, with the optional preferred proviso that such alkylidene when substituted with aryl having 6-10 carbon atoms always has at least 2, or at least 3, or at least 4, or at least 5, or at least 6, or more and up to 18 carbon atoms, and preferably has 2-6, 3-6, 4-6, or 5-6 and up to 18 carbon atoms;
e. when Y is ##EQU18## and R.sub.1, R.sub.2 and R.sub.3 are the same as defined under (a) immediately above,
R is the same as defined under (b) immediately above, and
R.sub.4 is defined individually in the same way as R.sub.3 is defined wherein R.sub.3 and R.sub.4 may be alike or different, with the proviso that R.sub.3 and R.sub.4 when taken together with the adjacent nitrogen atom represent N-containing heterocyclic as defined under (v) above;
f. when Y is ##EQU19## and R and R.sub.3 are the same as defined under (a) immediately above,
R.sub.1 and R.sub.2 each respectively is the same as defined under (viii) through (xiii) above, as the case maya be, and
R.sub.4 is the same as defined under (e) immediately above, with the proviso that R.sub.3 and R.sub.4 when taken together with the adjacent nitrogen atom represent N-containing heterocyclic as defined under (v) above; and
g. when Y is ##EQU20## and R, R.sub.1 and R.sub.2 are the same as defined under (a) immediately above;
R.sub.3 and R.sub.4 each respectively is the same as defined under (xv), (xvi), (xvii), (xviii) and (xix) above, as the case may be, with the proviso that R.sub.4 may also be hydrogen and that when R.sub.4 is hydrogen R.sub.3 is aliphatic as defined under (i) above but having always only 1-3 carbon atoms, or cycloaliphatic as defined under (ii) above, or substituted -aliphatic having 1-18 carbon atoms, -cycloaliphatic, -araliphatic or -aryl as defined under (i), (ii), (iii), (iv) when taken together with (xix), as the case may be, and with the further proviso that R.sub.3 and R.sub.4 when taken together with the adjacent nitrogen atom represent heterocyclic as defined under (v) above but always excluding oxygen as hetero atom.
Similarly, analogous coverage to that defined under I-(S)-GENERIC INVENTION through VII -- PREFERRED SPECIAL EMBODIMENT is intended for the instant new compounds; i.e. all cases where, when Y is S, R is not methyl or is not phenyl, or R.sub.1 and R.sub.2 are both not simultaneously hydrogen, or R.sub.3 is not methyl; or where, when Y is ##EQU21## R is not methyl or is not phenyl, or R.sub.1 and R.sub.2 are both not simultaneously hydrogen, or R.sub.3 and R.sub.4 are not simultaneously hydrogen, or when R.sub.4 is hydrogen R.sub.3 is at most C.sub.1-3 alkyl, or not phenyl, or not benzyl, or R.sub.3 and R.sub.4 when taken together withethe adjacent N-atom do not form morpholino.
It will be realized that as used herein the term "ylidene-amino" is meant to be synonymous with the term "ylidene-imino" so as to cover the hydrocarbyl-amino or hydrocarbyl-imino linkages --CH=N-- and ##EQU22## as the case may be (cf. the corresponding linkages of compounds 14, 15, 17-19, 27, 28, 35, 119-124, 127 and 194-233 for ##EQU23## when R.sub.1 and R.sub.2 are taken together). These linkages are to be distinguished from N-containing heterocyclic linkages of certain of the instant compounds (cf. the corresponding linkages of compounds 125, 126 and 128-133 for ##EQU24## when R.sub.1 and R.sub.2 are taken together with the adjacent N-atom, as well as those of compounds 13a, 25, 133 and 168 for ##EQU25## when R.sub.3 and R.sub.4 are taken together with the adjacent N-atom).
A preferred sub-group of compounds in accordance with the invention includes those of formula (I) wherein Y is S, R is branched lower alkyl or cycloalkyl, R.sub.3 is lower alkyl, and R.sub.1 and R.sub.2 are individually hydrogen or taken together are cycloalkylidene having 5-8 ring carbon atoms or alkylidene having 1-12 carbon atoms substituted with aryl having 6-10 ring carbon atoms or furyl, pyridyl, thienyl, pyrryl, chinolyl, thiazolyl, imidazolyl or indyl. Especially preferred are those wherein R is branched butyl, e.g. tert.-butyl, R.sub.3 is methyl, and R.sub.1 and R.sub.2 are individually hydrogen or taken together are cyclopentylidene, cyclohexylidene or lower alkylidene substituted with phenyl, furyl, nitrophenyl, lower alkyl phenyl or lower alkoxy phenyl, e.g. cyclohexylidene, benzylidene, nitrofurfurylidene, and the like.
Thus, 3-methylthio-4-(cyclohexylidene-amino)-6-tert.-butyl-1,2,4-triazine-5-one (221) shows very good general herbicidal activity on post-emergence and for pre-emergence is selective for soybeans, i.e. it will prevent growth of most plants and weeds but not of soybeans.
The very similar cyclopentyl compound (223), m.p. 78.degree.C., is similarly useful, as is the corresponding furfuryl-idene-2 compound (222), and can be prepared in the same manner as in Example 22.
2-methylthio-4-(benzylidene-amino)-6-tert.-butyl-1,2,4-triazine-5-one (236) has the same general properties and is also selective as to cotton and tomatoes on pre-emergence application. It is also effective in growing corn, potatoes, millet and peanuts applied to the extent of 0.3-2 kg/hectare. Surprisingly the compound also exhibits fungicidal activity, particularly against Alternaria which makes it especially useful in growing tomatoes. It also kills nematoeds on the soil when applied at 1 Kg/hectare. Its toxicity is quite low, i.e. LD.sub.50 when applied orally to rats is 1000 mg/Kg. It can be prepared in analogous manner according to Example 22 and has a melting point of 137.degree.C.
All of the foregoing compounds contemplated by the present invention possess the desired selective herbicidal properties, and especially the capability of selectively destroying weeds. It will be realized that the instant compounds possess total herbicidal action when used in large quantities, although selective herbicidal action section is obtained when used in smaller quantities. As contemplated herein, the term "weeds" is meant to include not only weeds in the narrow sense, but also in the broad sense, whereby to cover all plants and vegetation considered for the particular purposes in question.
It will be appreciated that the instant specification and examples are set forth by way of illustration and not limitation, and that various modifications and changes may be made without departing from the spirit and scope of the present invention.
