The post-emergent control of a broad spectrum of pests is accomplished by the post-emergent application of a pesticidally effective amount of a formulation comprised of at least one post-emergent, foliar absorbed, substantially water insoluble active ingredient dispersed in at least one substantially water miscible polar/nonpolar solvent which has a vapor pressure of not more than 760 mm of Hg at 20°C capable of dissolving a plant cuticle, including the cuticular wax, and, optionally a surface active agent which substantially prevents the active ingredient from precipitating upon dilution of the formulation with water. The formulation is initially applied to the surface of the foliage and is subsequently incorporated therein by the dissolution of the waxy layer of the foliage by the polar/nonpolar solvent.
利用后发生的控制广谱害虫的效果,通过施用一种有效量的杀虫剂配方来实现,该配方由至少一种后发性、叶面吸收、明显不溶于水的活性成分,分散在至少一种明显可溶于水的极性/非极性溶剂中组成,该溶剂在20°C时的蒸汽压不超过760毫米汞柱,能够溶解植物表皮,包括表皮蜡质,以及可选的表面活性剂,该表面活性剂在配方被稀释成水时,能够有效防止活性成分沉淀。该配方最初施于叶面表面,并随后通过极性/非极性溶剂溶解叶面的蜡质层而被吸收。
