摘要
通过对江苏省杨树烂皮病发生状况调查发现,在新沂,六合和仪征3个地区有杨树烂皮病发生。在调查的4 417株杨树中,平均发病率占11.32%;杨树烂皮病的发生与树种、树龄、地形、土壤、坡向以及虫害的关系均较密切。苗圃内不同药剂、配比度对杨树苗刮皮后的涂药试验发现,吡唑醚菌酯500,1 000,1 500倍液3种配比度的防治效果均在88%以上,嘧菌酯500倍液的防治效果高于80%。说明在苗圃用吡唑醚菌酯1 000倍和1 500倍液防治杨树烂皮病,可以取得良好的防治效果。
The investigation was made of Cytospora canker of poplar, occurred within Xinyi, Luhe and Yizheng. We found that the average disease incidence was 11.32% ,and that its occurrence got close relationships with tree species, age, to- pography, soil, slope aspect and pest. Actual chemical control in the field showed that the best control concentration out- doors was higher than the concentration indoors. The best control effect could be got by using the concentration diluted to 1 000 ＆ 1 500 times of CabrioTM.
