FIELD: agriculture.
SUBSTANCE: solid herbicidal composition contains: a) from 50 g of active ingredient per kg (g ai/kg) to 600 g ai/kg, based on the total weight of the composition, a first herbicidally active ingredient selected from a group consisting of ALS inhibiting enzyme herbicides and compounds of formulas 
where Ar is a phenyl group substituted with one to four substitutes independently selected from a group consisting of halogen, C1-C6 alkyl, C1-C6 alkoxy, C2-C4 alkoxyalkyl, C2-C6 alkylcarbonyl, C1-C6 alkylthio, C1-C6 haloalkyl, C1-C6 haloalkoxy, C2-C4 haloalkoxyalkyl, C2-C6 haloalkylcarbonyl, C1-C6 haloalkylthio, -OCH2CH2-, -OCH2CH2CH2-, -OCH2O- and -OCH2CH2O-; R is H or F; X is Cl or vinyl; Y is Cl, vinyl or methoxy; and salts and esters thereof; b) from 50 g of active ingredient per kg (g ai/kg) to 600 g ai/kg, based on the total weight of the composition, pyroxulam; c) from 50 g ai/kg to 600 g ai/kg, based on the total weight of the composition, cloquintoceic acid or salt thereof; d) from 30 g ai/kg to 250 g ai/kg, based on the total weight of the composition, lignosulphonate; e) from 10 g/kg to 100 g/kg, based on the total weight of the composition, of an anionic surfactant selected from a group comprising alkyl sulphate salts, alkylaryl sulphonate salts, soaps, alkyl naphthalene-sulphonate salts, sulphosuccinate salts of dialkyl ethers, taurates of N-alkyl-N-fatty acids, mono- and dialkylphosphates of esters and polycarboxylate salts; and f) from 50 g/kg to 250 g/kg, based on the total weight of the composition, a solid buffer selected from a group comprising ammonium sulphate, diammonium phosphate, citric acid, potassium acetate, sodium acetate and combinations thereof.
EFFECT: invention allows to increase the composition stability.
