国内外杀虫绿僵菌制剂的登记现状与剂型技术进展

生物农药在植物保护工作中日益受到重视。绿僵菌是重要的昆虫病原真菌,作为真菌杀虫剂已被成功应用于蝗虫、金龟子、象甲等多种害虫的田间防治。近40年来,已有83个绿僵菌产品在13个国家或地区获得注册,制剂研究与加工技术方面取得了新进展,可湿性粉剂、悬浮剂等传统剂型质量得到改善,超低容量剂、浸渍剂等新剂型可适应特殊应用环境,产品的防治对象涵盖范围更广。本文就国内外绿僵菌产品注册登记情况、制剂类型特性及制剂技术的载体、助剂和加工过程等主要因素进行综述,以期为我国真菌生物农药的科研、应用及产业发展提供基础依据。

Advances in registration and formulation techniques of Metarhizium biological insecticides

Bio-pesticides are increasingly being taken seriously in plant protection. Metarhizium spp. is an important insect pathogenic fungus and was studied as a fungal insecticide for the control of grasshoppers, beetles and other pests in fields. In the last 40 years, there have been 83 products of Metarhizium registered in 13 countries or regions of the world. New progresses in formulation techniques and product development had been made. The quality of traditional formulations such as wettable powders, suspensions and others has been improved. And new formulations, such as ULV agents and impregnating agents and so on, have been developed for applications in special environments. The registered products covered a wide range of target pests. This summary focuses on global registration of Metarhizium products, characteristics of formulation and main technical factors, including carriers, additives and processing, etc. It will have a positive role in promoting further development of fungal pesticide research, application and industry in China.
