[PROBLEMS] To provide an aqueous suspension pesticide composition in which degradation of an active ingredient of an agricultural chemical is inhibited.[MEANS FOR SOLVING PROBLEMS] An aqueous suspension-type pesticide composition containing a specific agricultural chemical active ingredient and an alkyl polyglycoside. A method for inhibiting the decomposition of the agricultural chemical active ingredient contained in an aqueous suspension pesticide composition, which comprises using a specific agricultural chemical active ingredient and an alkyl polyglycoside together. As the agricultural chemical active ingredient, pyrazosulfuron ethyl, halosulfuron methyl or azimsulfuron is preferable.Pesticidal active ingredients, alkylpolyglycosides, pyrazosulfuronethyl, halosulfuronmethyl, azimsulfuron[과제] 농약 활성성분의 분해가 억제되는 수성 현탁상 농약 조성물을 제공한다.[해결수단] 특정의 농약 활성성분과 알킬폴리글리코시드를 함유하는 수성 현탁상 농약 조성물. 특정의 농약 활성성분과 알킬폴리글리코시드를 병용하는 것을 특징으로 하는 수성 현탁상 농약 조성물에 포함되는 상기 농약 활성성분의 분해억제방법. 농약 활성성분으로서는, 피라조술푸론에틸, 할로술푸론메틸 또는 아짐술푸론이 바람직하다.
