METHOD FOR INDUCING VIRAL RESISTANCE IN PLANTS

The invention relates to a method for inducing viral resistance in plants which is characterized in that the plants, the soil or seeds are treated with an effective quantity of a compound, which is absorbed by the plants or seeds and which is of formula (I), wherein: X represents halogen C1-C4 alkyl or trifluoromethyl; m is equal to 0 or 1; Q represents C(=CH-CH3)-COOCH3, C(=CH- OCH3)-COOCH3, C(=CH-OCH3)-CONHCH3, C(=N-OCH3)-COOCH3, C(=N-OCH3)-CONHCH3 or N(- OCH3)- COOCH3; A represents -O-B, -CH2O-B, -OCH2-B, -CH=CH-B, -C=C-B, -CH2O- N=C(R1)-B or -CH2O-N=C)R1)-C(R2)=N-OR3, whereby B represents optionally substituted phenyl, naphthyl, 5-member or 6-member hetaryl or 5-member or 6- member heterocyclyl, containing one to three N atoms and/or one O or S atom or one or two O and/or S atoms; R1 represents hydrogen, cyano, alkyl, alkyl halide, cycloalkyl, alkoxy; R2 represents optionally substituted phenyl, phenylcarbonyl, phenylsulfonyl, 5-member or 6-member hetaryl, 5-member or 6- member hetaryl carbonyl or 5-member or 6-member hetaryl sulfonyl, or alkyl, cycloalkyl, alkenyl, alkynyl, alkylcarbonyl, alkenylcarbonyl, alkynylcarbonyl, alkylsulfonyl or C(=NOR.alpha.)-OR.beta., and; R3 represents hydrogen and optionally substituted alkyl, alkenyl and alkynyl.
