草原毛虫病毒杀虫剂的研制及其大面积应用

The Production and Application in Large Areas of GrNPV Pesticide

根据草原特殊的自然环境条件,研制一种以草原毛虫自身分离的核型多角体病毒和杆状芽胞菌为主体成分,外加Ca^(2+)、微量化学农药和光保护剂等辅助成分的草原毛虫病毒杀虫剂。该杀虫剂对草原毛虫具良好的防治效果,并在川青藏高原上的20多万公顷草地上应用,获得了巨大的经济和社会效益。

Gynaephora ruoergensis is a pest on Chuan- Qing--Zang plateau grassland. It causes serious harm and was controlled by chemical methods before. Now, we have studied and produced GrNPV, Bacillus thuringi ensis, Ca^(2+), little amount of chemical pesticide and light protective agent. This pesticide is effective in Gynaephora ruoergensis control, safe to human and livestock, has no environmental pollution and is harmless to the natural enemy of pest. We have obtained enormous ecomic benefit and social benefit after this pesti cide was used on 0.2 million hm^2 grassland on Chuan--Qing-Zang plateau.
