【摘要】 桑椹菌核病具有群体发病的特点。在2011年-2014年桑果成熟期,对桑椹菌核病进行了田间调查和药剂防治试验,初步摸索到一些流行规律。桑椹菌核病的流行与病原、桑树品种和气象环境条件有密切关系,与桑树栽植密度关系不大。使用化学药剂是目前防控菌核病的主要手段。作了5种杀菌剂防治方法、药剂喷施适期、农药残留等试验。在陕西果桑生产基地示范应用防治技术有效控制了菌核病流行,收到了良好效果。更多还原

【Abstract】 Mulberry Fruit Sclerotiniosis has the characteristics of population epidemic. I order to reduce the loss of the mulberry fruit, we investigated the occurrence in field and tested the control efficiency of several fungicides on this disease at Mulberry maturity period from 2011 to 2014 under natural occurrence condition, and find some primary epidemic regularity. The epidemic invasion of Mulberry Fruit Sclerotiniosis has a closely relationship with pathogen, mulberry cultivars and meteorological environmental conditions, and almost unrelated to mulberry planting density. Using fungicide is the primary means of prevention and control of the disease now based on five fungicide with different control methods, such as pharmaceutical spraying suitable period, pesticide residues and other tests. We achieved good results by demonstration and application these control techniques effectively prevent this disease invasion in Shaanxi mulberry fruit production area.更多还原
