摘　　要：桑椹菌核病是果用桑树的重要病害,为高效、安全控制该病对桑果生产的危害,进行了大田农药防治筛选试验。结果表明,70%甲基托布津可湿性粉剂500倍液、50%多菌灵-硫磺粉剂500倍液和1 000倍液对桑椹小粒性菌核病具有较好的防治效果,且对桑叶和桑椹无明显药害;70%甲基托布津粉剂1 000倍液、25%吡唑醚菌酯乳油1 500倍和3 000倍液以及40%嘧霉胺粉剂1 000倍液也有一定的防治效果。Mulberry sorosis disease is an important disease for mulberry fruit and results in decrement of yield of mulberry fruit and leaf. To control this disease effectively and safely in mulberry garden, 4 kinds of germicides were screened in this paper. The results indicated that control effects of 500 × solution of 70% Thiophanate-methyl, 500 × and 1000 × solution of 50% Carbendazim on mulberry sorosis disease are efficient. Moreover, they are safe to mulberry leaf and fruit. Therefore, we proposed that they can be applied in practice. Meanwhile, control effects of 70% 1 000 × solution of Thiophanate-methyl, 1 500 × and 3 000 × solution of 25% Pyraclostrobin EC and 1000 × solution of 40% Pyrimethanil are also quite good.
