来福灵是日本住友化学工业株式会社新近开发的杀虫剂,杀虫效果约为速灭杀丁的4倍.来福灵具有很强的触杀及胃毒作用,无内吸和薰蒸作用,是一种高效广谱、对人畜较安全的拟除虫菊酯类杀虫剂.1987年,我们用来福灵进行了防治棉铃虫的试验.试验在沙湾县大泉乡四队进行.试验设亩喷5%来福灵乳油10,20,30毫升,对照处理为亩喷速灭杀丁乳油30毫升,均兑水40—50公斤,另以喷清水为空白对照.试验小区150—240米~2,随机排列,重复3次.棉铃虫卵孵化盛期用工农-16型喷雾器喷施,喷后3,7,13天于每小区随机抽取50株,统计活虫数.
Laifu Ling is Japan’s Sumitomo Chemical Co., Ltd. recently developed insecticide, insecticidal effect is about 4 times faster than kill Ding.Laifen has a strong contact and stomach poisoning, no absorption and fumigation , Is a highly efficient broad-spectrum pyrethroid insecticide that is safer to humans and animals. In 1987, we used Fu Ling to test the control of cotton bollworm. The experiment was conducted at the Fourth Team of Daquan Township, Shawan County. Mu sprayed 5% of Laoling EC 10,20,30 ml, control treatment for the mu burst kill Ding EC 30 ml, all against the water 40-50 kg, and the other to spray water blank control test plot 150-240 m ~ 2, randomly arranged, repeated 3 times. Helicoverpa armigera eggs hatch peak sprayed with a worker-peasant -16 type sprayer, spray 3, 7, 13 days after spraying randomly selected in each plot 50, the number of live worms.
