烟粉虱的防治主要以化学药剂防治为主,因此产生抗药性,防治效果显著降低。苏云金杆菌是目前应用最广、用量最大的微生物杀虫剂,提速(苏云金杆菌片剂)是科学防治烟粉虱,确保保护地蔬菜安全生产的主要药剂。1试验目的本试验采用生物杀虫剂——提速防治保护地黄瓜烟粉虱,为该药在河北省大面积推广、合理安全使用提供科学依据。2试验设计供试作物为保护地黄瓜,防治对象为烟粉虱。试验药剂为提速片剂。试验设在承德县六沟镇中六沟村。
The control of Bemisia tabaci was mainly chemical control, which led to the emergence of drug resistance and the control effect was significantly reduced. Bacillus thuringiensis is currently the most widely used, the largest amount of microbial insecticide, speed (Bacillus thuringiensis tablet) is a scientific control of Bemisia tabaci, to ensure the safe production of vegetables to protect the main agent. 1 Objectives of the experiment This experiment uses biological pesticides - speed control and protection of cucumber whitefly, in order to provide a scientific basis for the large-scale promotion of the drug in Hebei Province, rational and safe use. 2 experimental design for the protection of cucumber crops, the control object Bemisia tabaci. Test drugs for the speed of tablets. The experiment is located in Zhonglugou Village, Liugou Town, Chengde County.
