摘　　要：桑葚菌核病是目前果桑发展的致命病害。为有效防治桑葚菌核病、生产无公害桑葚,筛选高效、低毒、低残留的杀菌剂势在必行。本试验选用5种低毒、低残留的杀菌剂,设3个浓度梯度开展桑葚菌核病田间药剂防治,对试验结果进行统计分析。结果表明：70%甲基硫菌灵可湿性粉剂800～1 200倍液、50%多菌灵可湿性粉剂500～1 000倍液对桑葚菌核病具有较好的防治效果,50%的腐霉利400～600倍可与甲基硫菌灵或多菌灵交替使用,且这3种杀菌剂对桑叶和桑葚无明显药害。At present, popcorn disease of mulberry sorosis is a great disadvantage to the development of mulberry. In order to control popcorn disease of mulberry sorosis effectively and produce non-pollu- tion mulberry, it is very imperative to screen some pesticides with high activity, low toxicity and low residue. Field experiment was carried out to investigate five pesticides with low toxicity and low resi- due, treated with 3 concentration gradients. The result shows that 800 - 1 200 times liquid of 70% thiophanate-methyl wettable powder and 500 - 1 000 times liquid of 50% carbendazol wettable powder had good control effects. Alternative use of 400 - 600 times liquid of 50% procymidone and thio- phanate-methyl or carbendazim had control effects and no obvious phytotoxicity.
