摘　　要：松材线虫病是世界上最具危险性的森林病害之一,自2000年传入湖北省以来,已在13个市州82个县(市、区)发生,对全省森林资源危害十分严重。通过进行松树树干注射免疫激活剂药效试验及使用不同剂量对比试验,研究注射免疫激活剂对松材线虫病防控效果。结果表明,不同剂量的药剂注射对松材线虫病防控效果存在差异,通过方差分析,各处理与对照组在5%水平上均有显著差异,说明打孔注药效果显著;正常剂量与增加剂量无显著差异,因此生产性防治时,使用更经济的正常剂量处理即可。进行树干注药的松树感病率都小于1.00%,感病率最低为0.09%,九峰国家森林公园、丹江口市松涛山庄、黄梅县五祖寺风景旅游林场、武当山景区4个地区没有整株枯死树,病死率为0;未进行树干注药的对照组松树感病率最低为3.00%,最高达15.00%,病死率最低为1.00%,最高达11.00%。丹江口市松涛山庄和武当山景区的试验结果是树干注药后2 a的调查结果,病死率都为0,说明树干注药后2 a仍对松树有保护效果,可显著降低病死率。Pine wilt disease is one of the most dangerous forest diseases in the world,since it was identified in Hubei province in 2000,it was occurred in 13 cities,82 counties(cities or districts),and seriously damaged the forest resources of the whole province.In this experiment,the efficacy test and dosage test of injecting immune activator into pine trees were used to study the control effect of injecting immune activator on Pine wilt disease.The results showed that there were also differences in the effect of different doses of injection on the control of pine wood nematode disease.Through variance analysis,there were significant differences between each treatment and the control group at the level of 5%,indicating that the effect of injection immune activator into pine trees was significant,and there was no significant difference between the normal dose and the increased dose.Therefore,the more economical normal dose could be used for productive control.The infection rate was less then 1.00%by injecting immune activator into pine trees,the lowest infection rate was 0.09%.There were no whole dead trees in Jiufeng National Forest Park,Danjiangkou Songtao Mountain Villa,Huangmei Wuzu Temple Scenic Forest Farm,and Wudang Mountain Scenic Area,and the fatality rate was 0.But without trunk injection,the lowest infection rate was 3.00%,up to 15%,the lowest fatality rate was 1.00%,up to 11.00%.The results of Songtao Mountain Villa and Wudang Mountain Scenic Area in Danjiangkou City were the investigation results of two years after the trunk injection,and the fatality rates were both 0,indicating that the trunk injection could still protect the pine trees two years after the trunk injection,which could significantly reduce the fatality rate.
