摘　　要：地下害虫是危害高粱苗移栽后最重要的害虫,主要种类有小地老虎、蝼蛄、蛴螬等,常造成断苗缺窝。高粱对很多农药敏感,可防治高粱病虫害的药剂不多,尤其是防治有机高粱的农药要求更加严格。本文通过对符合有机投入品要求的3种生物农药采用浸根和喷施进行有机高粱苗期地下害虫防治试验。结果表明,3种生物农药都具有较好的防治效果,且在施药方式上浸根的防治效果整体优于喷施,持效性也更加明显;18个处理中,印楝油800倍液、0.5%苦参碱1000倍液和0.5%藜芦碱500倍液处理的防控效果较好。Soil pests are the most important pests for damaging sorghum during the seeding stage after transplantation. The main species of the pests include Agrotis ypsilon, Gryllotalpa spps., and white grub etc. They might interrupt the normal seeding. Sorghum is sensitive to a lot of pesticides. Accordingly, there are only a few pesticides for pest control of sorghum, especially of organic sorghum. In this paper, 3 kinds of bio-pesticides which meet the requirements of organic sorghum were applied in pest control experiments by root soaking/spraying during the seeding stage. The results suggested that, all the 3 kinds of biological pesticides had good pest control effects;root soaking had better effects and longer duration than spraying;among 18 pesticide usages, 800- fold diluted azadirachtin oil solution, 1000-fold diluted 0.5 % matrine solution, and 500-fold diluted 0.5 % veratrine solution had satisfactory pest control effects.
