杀虫双大粒剂系中国农科院植保所研制的新剂型,含有效成分5％,扁圆形颗粒,粒径8毫米,粒重0.3—0.6克。经1982—1985年水泥池及田间试验表明:稻田保水1天以上是杀虫双大粒剂发挥药效的技术关键;它对稻螟类和稻蓟马防效优异;对生态环境(天敌蜘蛛、鱼、蚕、糙米中残留等)的影响小;撒施大粒剂比常量喷雾提高工效约16倍,减经了劳动强度;对稻田有益生物无害;杀虫双大粒剂在稻田的应用,为稻田害虫综合防治提供一种有效的手段。
Pesticide double big granule The Chinese Academy of Agricultural Sciences Institute of Plant Protection developed a new dosage form, containing 5% active ingredient, oblate granules, grain size 8 mm, grain weight 0.3-0.6 grams. After 1982-1995 years of cement ponds and field trials showed that: rice paddy water more than one day is the key to pesticides Shuangdai Pharmacy to play a key; it is excellent for rice stem borer and rice thrips; control of the ecological environment (natural enemies spiders, Fish, silkworm, brown rice residues, etc.) of the impact of small; sprinkling large particles than the constant spray to improve work efficiency of about 16 times, reducing the labor intensity; beneficial to rice paddy bio-friendly; Comprehensive prevention and control of rice field pests provides an effective means.
