Based on the 'negativety-correlated cross resistance' phenomenon betweell N-phenylcarbamates and benzimidazole fungicides, the mixtures of diethofencarb with either thiophanatemethyl or procymidone were developed to control Botrytis cinerea by Takahashi et al.(1988). Isolates of Corynespora melonis resistant to benzimidazole were more sensitive to diethofencarb on PSA medium than those sensitive to diethofencarb. In both of preventive and curative pot tests, diethofencarb was effective to control Corynespora target leaf spot of cucumber caused by the resistant strains, and the mixtures of diethofencarb with either thiophanatemethyl or procymidone were highly effective in field tests. 'Negatively-correlated cross resistance' between benzimidazole and diethofencarb can be used for control of C. melonis, since isolates moderately resistant to benzimidazole and resistant to both of benzimidazole and diethofencarb were not found at all.
