Stable agrochemical compositions are provided by incorporating at least one of the α -unsaturated amine derivatives having the following formula:
wherein one of X¹ and X² is an electron attracting group and the other is hydrogen or an electron attracting group; R¹ is a group attached through a nitrogen atom; R² is hydrogen or a group attached through a carbon, nitrogen, or oxygen atom; n is an integer of 0, 1, or 2; and A is a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted cyclic hydrocarbon group; and salts thereof, into an agrochemically acceptable solid carrier (clay minerals capable of adsorption (including fuller's earth, terra alba, bentonite, and activated fuller's earth), zeolite, activated charcoal, and β -cyclodextrin, etc.) under a pH 5.5 or less condition. The agrochemical (pesticidal) compositions exert potent shelf life and light-resistance.
通过掺入至少一种具有下式的α-不饱和胺衍生物,可提供稳定的农用化学品组合物:
其中 X¹ 和 X² 中的一个是引电子基团,另一个是氢或引电子基团;R¹ 是通过氮原子连接的基团;R² 是氢或通过碳原子、氮原子或氧原子连接的基团;n 是 0、1 或 2 的整数;和 A 是取代或未取代的杂环基团或取代或未取代的环烃基团;以及它们的盐,在 pH 值为 5.5 或更高的条件下,加入到农业化学上可接受的固体载体(可吸附的粘土矿物(包括富勒土、白土、膨润土和活性富勒土)、沸石、活性炭和 β - 环糊精等)中。在 pH 值为 5.5 或更低的条件下使用。农用化学品(杀虫剂)组合物具有很强的保质期和耐光性。
