@ An agricultural chemical preparation in the form of aqueous suspension is proposed, which preparation comprises at least one active ingredient, at least one nonionic surfactant having an HLB value of 11 or less, a thickener and the balance of water, provided that the active ingredient is hardly soluble or insoluble in water and soluble or miscible in the nonionic surfactant at ordinary or elevated temperatures. The preparation is excellent is stability of the active ingredient, spreadability and residual effect, and usable without any risk of inflammation or toxicity to mammals, because of using no organic solvents.
提出了一种水悬浮剂形式的农用化学制剂,该制剂由至少一种活性成分、至少一种 HLB 值小于或等于 11 的非离子表面活性剂、增稠剂和余量的水组成,条件是活性成分在常温或高温下几乎不溶于水或不溶于水,且可溶于或混溶于非离子表面活性剂。由于不使用有机溶剂,该制剂在活性成分的稳定性、可涂抹性和残留效果方面都非常出色,而且使用时不会对哺乳动物造成任何炎症或毒性风险。
