摘要
结合四川省会东县姜州林区华山松立枯病的发生规律,在发病初期,选取50%敌克松可湿性粉剂700倍液、50%福美双可湿性粉剂700倍液、70%普力克水剂700倍液、20%甲基立枯磷乳油700倍液和75%百菌清可湿性粉剂700倍液5种药剂进行防治试验。结果显示,华山松立枯病的发病率在不同时期呈现显著变化,即早期发病率为30%、中期上升至48%、晚期达到54%;不同药剂的防治效果存在差异,但都显著优于未处理对照组,其中50%敌克松可湿性粉剂700倍液防治效果最佳,50%福美双可湿性粉剂700倍液防治效果次之。由此可得,华山松立枯病在早期、中期和晚期的发病率逐渐上升,防治工作应在早期介入,以阻止病害扩散;50%敌克松和50%福美双为防治华山松立枯病的最佳药剂,建议在实际防治中优先使用。
Through regular observation at different stages of wilt disease,the growth of Pinus armandii seedlings and the incidence of wilt disease were recorded,and the occurrence rules and effective control measures of Pinus armandii wilt disease were discussed in Jiangzhou forest area of Dongxian County.The results showed that the incidence of wilt disease of Pinus armandii showed significant changes in different periods.The incidence of Pinus armandii wilt disease in the early,middle and late stages increased gradually,and the prevention and control work should be involved in the early stage to prevent the spread of wilt disease.50%diaxone and 50%fumeisong were the best agents for the prevention and control of Pinus armandii,and it was recommended to use them first in practical control.This study provided scientific basis and practical guidance for the prevention and control of Pinus armandii wilt disease,which was helpful to protect forest health and promote the sustainable development of forestry.
