815农药助剂是河北农业大学植保系研制开发的一种非离子表面活性剂,它具有与多数农药乳油配伍性好,加入农药中可增加农药在植物表面、害虫体壁上的湿润、展着性,耐雨水冲刷,增加害虫体壁的渗透性,提高速效性,增加药效,尤其是对难防治的大龄棉铃虫幼虫,更表现出优异的防效。本品已广泛应用于棉花、果树、粮食作物及蔬菜、瓜类等作物。 一、降低表面张力,增加湿润、展着能力 815稀释2500倍的表面张力为28.3达因/厘米,表面张力降低(10℃)61.9％,能在蜡质层较多的叶面、果面,害虫体壁上湿润展着,能提高防效。
815 Pesticide Additives is a kind of nonionic surfactant developed by Plant Protection Department of Hebei Agricultural University. It has compatibility with most pesticide ECs. Adding pesticides can increase the wetting of pesticides on plant surface and pest body wall, Sexual, rain-resistant erosion, increase the permeability of the pest wall, improve the quick-acting, increase the efficacy, especially for the control of large-scale bollworm larvae, but also showed excellent control effect. This product has been widely used in cotton, fruit trees, food crops and vegetables, melons and other crops. First, to reduce the surface tension, increase the wetting, spreading ability 815 diluted 2500 times the surface tension of 28.3 dyne / cm, the surface tension decreased (10 ℃) 61.9%, in the waxy layer more foliage, Pest wall wet display, can improve the control effect.
