摘　　要：2013年10～12月，采用松脂酸钠、松脂酸铜、噻霉酮、代森锰锌等5种药剂对核桃膏药病进行防治试验。结果表明，喷施1600倍液的松脂酸钠、松脂酸铜、噻霉酮、代森锰锌，对核桃膏药病的防治效果分别为44.0％、19.7％、36.6％和29.5％；而喷施其800倍液，防治效果分别为76.9％～80.7％、13.3％～20.7％、65.1％～78.3％和67.4％～77.5％。松脂酸钠、噻霉酮、代森锰锌等3种药剂对核桃膏药病具有较好的防治效果，尤以松脂酸钠防治效果最好。涂白剂对核桃膏药病具有一定的防治效果，而松脂酸铜的防治效果不明显。To select efficient fungicides for walnut plaster disease , the effects of sodium abietate , copper abietate , benziothiazolinone , mancozeb and white coating agent were tested .The results showed that the prevention rate of sodium abietate , copper abietate , benziothiazolinone , mancozeb were 44.0 %, 19.7 %, 36.6 % and 29.5 %respectively when these fungicides were diluted 1 600 times.If these fungicides were diluted 800 times, their pre-vention rate were 76.9 %~80.7 %, 13.3 %~20.7 %, 65.1 %~78.3 % and 67.4 %~77.5 %.Sodium abietate, benziothiazolinone and mancozeb had significant prevention function for walnut plaster disease , especially sodium abietate.White coating agent had certain effect to this disease , while the effect of copper abietate was not significiant.
