PROBLEM TO BE SOLVED: To provide a method of alleviating contamination on a surface of a field crop in which a medicine benefit of an agrichemical is stably held and in addition contamination of a surface of a field crop is alleviated.SOLUTION: The agrichemical spray liquid which includes an adjuvant composition including: (A) 45-85 mass% of total content of sodium dialkyl sulfosuccinate and polyoxyethylene alkyl ether as a surfactant component and (B) 5-40 mass% of a component for pour point descent is sprayed to field crops. Even when drift relieving spraying, the alleviating benefit is attained.COPYRIGHT: (C)2010,JPO&INPIT【課題】農薬薬効効果を安定に保持しながら、尚かつ農作物表面の汚れを軽減する方法を提供する。【解決手段】以下の(A)及び(B)(A)界面活性剤成分としてのジアルキルスルホコハク酸ナトリウム及びポリオキシエチレンアルキルエーテルの合計含有量が45%~85質量%(B)流動点降下用成分を5~40質量%を含有するアジュバント組成物を含む農薬散布液を農作物に散布する。ドリフト軽減散布に際しても汚れ軽減効果が達成される。【選択図】なし
