PURPOSE: A method for controlling parasitic fungi in cultivated plants having modified pathogenic resistance against certain parasitic fungi is provided which treats the cultivated plants with an active substance from the strobilurin class. CONSTITUTION: A method comprises a step of treating the plants having bacilli-resistance with an active compound of the formula IA or IB, where a dotted line is a single bond or a double bond; R' is selected from the group consisting of -C£CO2CH3|=CHOCH3, -C£CO2CH3|=NOCH3, -C£CONHCH3|=NOCH3, -C£CO2CH3|=CHCH3, -C£CO2CH3|=CHCH2CH3, -C£COCH3|=NOCH3, -C£COCH2CH3|=NOCH3, -N(OCH3)-CO2CH3, -N(CH3)-CO2CH3 and -N(CH2CH3)-CO2CH3; R" is a C-organic group, wherein the C-organic group is directly bonded or bonded through oxy, mercapto, amino or alkylamino or forms substituted or unsubstituted, partially or completely unsaturated system containing a hetero atom selected from the group consisting of oxygen, sulfur and nitrogen other than a carbon cyclic member with X group and Q or T, where it is bonded; R¬x is selected from the group consisting of -OC£CO2CH3|=CHOCH3, -OC£CO2CH3|=CHCH3, -OC£CO2CH3|=CHCH2CH3, -SC£CO2CH3|=CHOCHE, -SC£CO2CH3|=CHCH3, SC£CO2CH3|=CHCH2CH3, -N9CH30C£C02CH3|=CHOCH3, -N(CH3)C£CO2CH3|=NOCHE, -CH2C£CO2CH3|=CHOCH3, -CH2C£CO2CH3|=NOCH3, -CH2C£CONHCH3|=NOCH3; R¬y is oxygen, sulfur, =CH- or =N-; n is an integer of 0-3, provided that n is over 1, X is able to be different; X is cyano, nitro, halogen, C1-4 alkyl, C1-4 haloalkyl, C1-4 alkoxy, C1-4 haloalkoxy, C1-4 alkylthio, or in case of n being over 1, it is bonded to two carbon atoms adjacent to a phenyl ring or X is one selected from the group consisting of C3-5-alkylene, C3-5-alkenylene, oxy-C2-4-alkylene, oxy-C1-3-alkyleneoxy, oxy-C2-4-alkenylene, oxy-C2-4-alkylene, oxy-C1-3-alkyleneoxy, oxy-C2-4-alkenylene, oxy-C2-4-alkenyleneoxy or butadiene-di-yl, all of which have 1-3 radicals of halogen, C1-4-alkyl, C1-4-haloalkyl, C1-4-alkoxy, C1-4-haloalkoxy or C1-4-alkylthio; Y is either =C- or -N-; Q is selected from the group consisting of phenyl, pyrollyl, thienyl, puryl, pyrazollyl, imidazollyl, oxazollyl, isooxazollyl, thiazollyl, thiadiazolly, triazollyl, pyridinyl, 2-pyridonyl, pyrimidinyl and triazinyl; and T is phenyl, oxazollyl, thiazollyl, oxadiazollyl, pyrimidinyl or triazinyl.
