Abstract: An agrochemical composition comprising a propylene glycol fatty acid monoester and fenbutatin oxide in a proportion of 1:150 to 150:1 in terms of a mass ratio (propylene glycol fatty acid monoester:fenbutatin oxide) shows an excellent control effect on pests, hyposensitive mites having reduced sensitivity to chemicals, eggs of mites, and pests other than mites in all stages of growth, even when the composition is applied in a small amount. A pest control method comprising applying the propylene glycol fatty acid monoester and fenbutatin oxide in a proportion of 1:150 to 150:1 in terms of a mass ratio (propylene glycol fatty acid monoester:fenbutatin oxide) to pests or a habitat of the pests also shows an excellent control effect.

Abstract: The invention has as its object the provision of an agrochemical composition for pest control, by which an excellent control effect is achieved on pests, hyposensitive mites having reduced sensitivity to chemicals and eggs of the mites, and other pests of all stages of growth than the mites even when the composition is applied in a small amount, and a pest control method. The agrochemical composition for pest control comprises a propylene glycol fatty acid monoester and fenbutatin oxide in a proportion of 1:150 to 150:1 in terms of a mass ratio (propylene glycol fatty acid monoester:fenbutatin oxide). The pest control method comprises applying the propylene glycol fatty acid monoester and fenbutatin oxide in a proportion of 1:150 to 150:1 in terms of a mass ratio (propylene glycol fatty acid monoester:fenbutatin oxide) to pests or a habitat of the pests.
