Primary Report on Test for Control of Dendrolimus Punctatus with Oil-based Suspension of Bt

摘要:

利用苏云金杆菌的新剂型——油悬浮剂进行防治马尾松毛虫试验，试验结果表明：该剂每hm^23000mL、4500mL、6000mL3种施药量，其防治效果在1％显著水平下与4000倍敌杀死比较差异显著。

Abstract:

Oil-based suspension, a new formulation of Bt was used to control Dendrolimus punctatus. The results showed that control effects of oil-based suspension for Bt with pesticide application rates of 3 000 mL, 4500 mL and 6 000 mL per hm 2 were relatively siginificantly differed from that by Decis under 1% of significant level.
