经过两年分别在四个省份开展0.3%辛硫磷颗粒剂防治甘蔗蔗龟的试验,探索有效剂量,观察和评估该药剂对甘蔗及有益天敌生物的安全性。试验结果:0.3%辛硫磷颗粒剂的有效使用剂量为100kg~150kg/666.7m2(有效成分用量为4500~6750g/hm2),该药剂对甘蔗安全、无药害,且有助长作用;对有益的天敌生物(如寄生蜂、蚜茧蜂、赤眼蜂、瓢虫等)没有不良影响,同时对蔗螟、蓟马、象甲等甘蔗害虫具有兼治作用。本试验研究为0.3%辛硫磷颗粒剂申报甘蔗农药登记和推广应用提供了扎实的试验基础和有力的科学依据。
After two years in each of the four provinces, 0.3% phoxim granules were used to control sugarcane cane turtles. The effective dose was explored and the safety of the pesticide against sugarcane and beneficial natural enemies was observed and evaluated. Test results: 0.3% phoxim granules effective dose of 100kg ~ 150kg / 666.7m2 (active ingredient dosage of 4500 ~ 6750g / hm2), the agent of sugar cane safe, no phytotoxicity, and contribute to the role of beneficial; (Such as parasitic wasps, aphid Braconidae, Trichogramma, ladybugs, etc.) have no adverse effects, while the sugarcane pests on sugarcane borer, thrips, weevil, etc. have a role. The experimental study provided a solid experimental basis and strong scientific basis for declaring the application and registration of 0.3% phoxim granules in sugarcane pesticides.
