Investigation and Control of Tussah Rust in Xiuyan County

对岫岩县8个林区的柞树锈病发病率和病情指数进行了调查,采用4种杀菌剂对柞树锈病进行药剂防治,结果表明:5月中旬至10月中旬,岫岩县8个林区的柞树锈病发病率和病情指数随时间呈增长趋势;供试药剂中,烯唑醇和吡唑醚菌酯对柞树锈病具有很好的防治效果,明显优于传统药剂代森锰锌和石硫合剂。

The incidence and disease index of tussah rust in eight forest areas of Xiuyan county were investigated,and four fungicides were used to control the rust of oak tree.The results showed that:from the middle of May to the middle of October,the incidence and disease index of tussah rust in eight forest areas of Xiuyan County showed an increasing trend with time.Among the pesticides tested,alkenolyl alcohol and pyrazolyl ester had excellent control effect on oak rust,which was obviously superior to traditional fungicides such as mancozeb and stone sulfur mixture.
