松茸毒蛾林间无公害防治试验

Pollution Free Control Experiment of Tricholoma matsutake and Moth in Forest

在福建省宁化国有林场发生松茸毒蛾的马尾松林中应用印楝素乳油、苦参碱水剂、苏云金杆菌悬浮剂、森得保粉剂4种药剂对松茸毒蛾进行林间无公害防治试验。结果表明,施药14 d后松茸毒蛾校正后的最低死亡率为88.2%、最高死亡率为93.5%,4种药剂均具有显著的杀虫效果,其中以森得保粉剂的校正死亡率最高且与其他3种药剂差异显著。林间无公害防治松茸毒蛾可优先采用森得保粉剂。

Four chemicals,Azadirachtin Emulsion,matrine,Bacillus thuringiensis suspension and sendebao powder,were used to control Tricholoma matsutake in Pinus massoniana forest in Ninghua State-owned Forest Farm of Fujian Province.The results showed that after 14 days of application,the lowest mortality rate was 88.2%and the highest mortality rate was 93.5%.All the four insecticides had significant insecticidal effect,among which the corrected mortality rate of sendebao powder was the highest and significantly different from the other three insecticides.Sendebao powder can be used preferentially in forest pollution-free control of Tricholoma matsutake.
