【摘要】 通过对崇明县松外松果桑园内桑椹的发病症状及其病原的调查表明,园内有3种菌核病发生,分别为桑椹肥大性菌核病、桑椹缩小性菌核病和桑椹小粒性菌核病,其病原菌的生物学特性明显不同。田间药剂防治表明,25%阿米西达SC与常规农药多菌灵、甲基托布津具有相同的防效,可在生产上推广应用。更多还原

【Abstract】 The investigation of a mulberry orchard in Chongming County,Shanghai showed that the popcorn disease,that is,Ciboria shiraiana(P.Henn) Wketz,Mitrula shiraiana(P.Henn.) Ito et Imai and Ciboria carunculoides(Siegl.et Jenk) Whetz.et Wolf,occurred,and each kind of pathogeny had its own distinct biological characters.The chemical control tests in field showed that 25% Amistar SC was proved to have the same control effect on popcorn disease as the conventional pesticides carbendazim and thiophanate-methyl.Therefore Amistar could be applied in production to control popcorn disease of mulberry soroses.更多还原
