  • Publication number: 20040110637
    Abstract: Method of protecting crop plants from phytotoxic side-effects of pesticides which comprises applying to the seed of a crop plant prior to sowing an effective amount of a compound of the formula (I) or a salt thereof, in which R1 is phenyl which is unsubstituted or substituted, R2 is (C1-C6) alkyl, (C3-C6) cyclalkyl or phenyl, each of the 3 last-mentioned radicals is unsubstituted or substituted, R3 is hydrogen or a hydrocarbon radical having 1 to 18 C-atoms which is unsubstituted or substituted. The safener of formula (I) is preferably isoxadifen or isoxadifen-ethyl. The seed treated crop plants are safened against the application of pesticides, particularly herbicides applied pre- or postemergent to the cultivation area.
