花生白绢病在临沂市已成为为害花生的主要病害。该病以菌核和菌丝体在土壤中及病残体上越冬,翌年侵染期越冬菌核、菌丝体萌发成菌丝或产生芽管,从花生根茎部表皮或伤口侵入,形成初侵染;7~9月份气温在20~35℃时,由于高温高湿的气候条件,该病发生迅速。其暴发成灾的关键因素是气候条件;同时病情与品种、栽培管理也存在密切关系,花生田间湿渍、杂草丛生、生长茂密和连作以及其他病虫为害均有利于发病;防治要以农业措施为基础,实行抗病育种、轮作、改良土壤、加强栽培管理等措施切断传播途径,减少和减轻为害。另外,播种期药剂拌种、发病期进行药剂保护也是控制该病发生的有效措施。
Peanut Sclerotium in Linyi City has become the main pest damage. The disease with sclerotia and mycelium in the soil and disease overwintering on winter, the next year overwintering during the infection sclerotium, mycelium germination or mycelial germ tube, from the roots of peanut rhizome or wound invasion, the formation of early Infection; 7 ~ September temperature 20 ~ 35 ℃, due to high temperature and humidity of the climatic conditions, the disease occurs rapidly.
