COMBINATIONS OF PHENYLSULFONYLUREA HERBICIDES WITH ANTIDOTES AND METHOD OF PROTECTION OF CULTURED PLANTS FROM ADVERSE PHYTOTOXIC EFFECTS OF PHENYLSULFONYLUREA HERBICIDES Russian patent published in 2003 - IPC

FIELD: organic chemistry, herbicides, agriculture. SUBSTANCE: invention describes herbicide-antidote composition comprising derivative of phenyl-sulfonulurea as herbicide - compound of the formula (A) or its salt of alkaline metals where W is oxygen atom; A is group of the formula CR¹R⁴ where R¹ and R⁴ mean oxygen atom; Q is oxygen atom or group NR⁶; M = 0 or 1; R¹ is alkyl with number of carbon atoms from 1 to 6; R² is hydrogen atom, alkyl with number of carbon atoms from 1 to 6; R³ means COR¹¹, COOR¹², SO₂R²¹ where R¹¹ is hydrogen atom, alkyl with number of carbon atoms from 1 to 6; R¹² is alkyl with number of carbon atoms from 1 to 6; R⁵ is hydrogen atom; R⁶ is hydrogen atom, alkyl with number of carbon atoms from 1 to 4; X¹, X² mean independently each of other alkoxyl-group with number of carbon atoms from 1 to 6; Z is group CH and comprising as antidote compound of the formula (B1) where X¹ is halogen atom; Z¹ means OR⁷ where R⁷ is alkyl with number of carbon atoms from 1 to 6; n¹ = 1 or 2; W¹ means the formula (W1) and (W2) ; R⁹ is alkyl with number of carbon atoms from 1 to 8; R¹⁰ is alkyl with number of carbon atoms from 1 to 8; m¹ = 0 taken in the weight ratio of compound (A) to compound (B1) = from 10:1 to 1:10. Invention describes also method of protection of cultured plants from adverse phytotoxic effects of herbicides of type A by application of effective dose of antidote of type B1 with herbicide simultaneously on plants, parts of plants, seeds of plants or planting areas taken in the weight ratio of (A) to (B1) = from 10:1 to 1:10. EFFECT: enhanced herbicide activity, absence of phytotoxicity. 7 cl, 8 tbl
