METHOD FOR CONTROLLING BACTERIAL DISEASE DAMAGE OF PLANT USING PHENYLACETONITRILE DERIVATIVE

摘要

Provided are an agricultural and horticultural agent having an improved effect on a bacterial disease damage of plants caused by Ralstonia solanacearum and the like, which are considered as an uncontrollable disease damage and become severe problems at a production site, and a control method using the same. The present invention applies a phenylacetonitrile derivative defined in formula [1].(In the formula, R₁ represents a hydrogen atom, a C1-C3 alkyl group, or COCF₃, R₂ represents a hydrogen atom, a C1-C3 alkyl group, or a halogen atom, R₃ and R⁵ each independently represent a hydrogen atom or a halogen atom, R₄ represents a hydrogen atom, a halogen atom, a phenoxy group, or a C1-C3 alkyl group, and R₆ represents a hydrogen atom.)
