核桃膏药病化学防治试验

Chemical Control Experiments on Walnut Plaster Disease

为筛选出对核桃膏药病防效较好的药剂,进行子代森锰锌、噻霉酮、松脂酸钠3种药剂防治核桃膏药病的试验,结果表明:在核桃树膏药病发病初期,分别使用代森锰锌、噻霉酮、松脂酸钠800倍稀释液对核桃树进行整株喷施,对核桃膏药病的防治效果分别为70.5%、65.9%、77.5%。试验使用的3种药剂对核桃膏药病都表现出了较好的防治效果,其中,松脂酸钠的防效最好,代森锰锌的防治效果次之,噻霉酮在3种试验药剂中防效最低。

In order to select efficient fungicides to control walnut plaster disease,the experiments of controlling walnut plaster disease by adopting mancozeb,benziothiazolinone sodium abietate were conducted.Result shows that800 times diluents of mancozeb,benziothiazolinone sodium abietate were sprayed on walnut trees in early onset;the control effect is 70.5%,65.9% 77.5% respectively.Ancozeb,benziothiazolinone and sodium abietate show optimal effect for walnut plaster disease;the descending order of control effect is sodium abietatemancozebbenziothiazolinone.
