Abstract
This invention relates to compositions comprising 1-aryl-4,5-dihydro-1,2,4-triazol-5(1H)-ones (triazolinones) in combination with the herbicide (2,4-dichlorophenoxy)acetic acid (2,4-D), or like substituted phenoxyalkanoic acids, or esters, or alkali metal or ammonium salts thereof; or with certain herbicidal sulfonylureas, or mixtures of these classes of compounds, to provide herbicidal compositions which are highly effective against a broad array of crop weeds, particularly broadleaf weeds, in crops such as wheat.
Claims12
A synergistic herbicidal composition comprising a herbicidally effective amount of the combination of:
- (1) a triazolinone of the formula ##STR6## in which R is halogen or lower alkyl;
- R.sup.1 is haloalkyl;
- X is hydrogen, halogen, alkyl, haloalkyl, alkoxy or nitro;
- Y is hydrogen, halogen, alkyl, haloalkyl, alkoxy, haloalkyl, halo lower alkylsulfinyl, or halo lower alkoxy;
- Q is --CH(R.sup.2)C(R.sup.3)(R.sup.4)Q' or --CH.dbd.C(R.sup.4)Q';
- R.sup.2 is H or halogen;
- R.sup.3 is halogen;
- R.sup.4 is H or lower alkyl;
- Q' is CO.sub.2 H, CO.sub.2 R.sup.5, CON(R.sup.6)(R.sup.7), CN, CHO, or C(O)R.sup.5 ;
- R.sup.5 is alkyl, alkoxycarbonylalkyl, cycloalkyl, benzyl, chlorobenzyl, alkylbenzyl, or haloalkylbenzyl;
- and each of R.sup.6 and R.sup.7 is independently H, or a radical which is an alkyl, cycloalkyl, alkenyl, alkynyl, alkoxy, phenyl, benzyl, or SO.sub.2 R.sup.6 (in which R.sup.6 is other than H) or is one of said radicals substituted by halogen, alkyl, or cyano;
- or a base-addition salt of the compound in which Q' is CO.sub.2 H;
- with the proviso that any alkyl, alkenyl, or alkynyl moiety have less than 6 carbon atoms and that any cycloalkyl moiety have 3 to 7 carbon atoms, and (2) dichloro- or chloro-lower alkylphenoxy lower alkanoic acids, or their corresponding herbicidally effective esters, or alkali metal or ammonium salts, in admixture with a suitable carrier.
