摘要
通过杀虫双药剂对蚕桑的破坏性和安全性试验,明确了杀虫双对家蚕具有明显的毒害作用,桑树根系对杀虫双也有一定的吸收能力,在采用安全施药方法和有效低用量的前提下,杀虫双颗粒剂可以作为蚕桑地区防治水稻三化螟等害虫的高效对口农药,与潮土充分拌和吸附其全部粉末后撒施是值得推广的最佳施药方法,对桑根能伸入的田块以使用杀螟松等药剂较为合适,蚕桑地区不宜使用杀虫双水剂,以策安全。
According to the results of destructive and safe tests of Dimehypo, S. S-(2-dimethylamino)-1.3-propanediyl) in sericulture, it was showed that Dimehypo had obvious poisoning effect on silkworms, and root systems of mulberry might absorb Dimehypo, nevertheless Dimehypo FG couldn't have obvious defavorable effects on silkworms on the premise of using safe application methods of insecticides at efficient low dosages. These results suggest that the Dimehypo FG may be used as the best insecticide for controlling rice insect pests, such as yellow rice borer, etc., and a recommendable safe application method of the insecticide worthy to be popularized in sericultural regions is to fully mix up this insecticide with fine damp soil; but it will be preferable to use Sumithion in the fields where mulberry root systems can well spread. Moreover use of Dimehypo SL must be forbidden in sericultural regions.
