灭幼脲三号胶悬剂是一种昆虫兰长调节剂,主要通过抑制昆虫表皮几丁质的合成来阻止昆虫蜕皮从而达到杀虫目的。具有迟效、保护天敌等作用。为此,我们于1987～1988年在中宁、灵武两地进行了此项试验,目的是探索灭幼脲三号防治粘虫的经济用量,为示范、推广提供依据。一、试验方法本试验共设5个处理,即25％灭幼三号亩用量30、35、40克,敌敌畏亩用量40克,空白对照。随
Chlorfenapyr 3 suspending agent is an insect longlan regulator, mainly by inhibiting the synthesis of insect epidermal chitin to prevent insect molting so as to achieve the purpose of insecticide. With delayed, to protect natural enemies and other effects. For this reason, we carried out this trial in Zhongning and Lingwu between 1987 and 1988 with the purpose of exploring the economic use of MBH III in control of armyworms and providing the basis for demonstration and promotion. First, the test method A total of five treatments in this experiment, that is, 25% of off-kilogram on the 3rd amount of 30,35,40 grams of mu, enemy dichlorvos amount of 40 grams of acres, a blank control.
