西瓜炭疽病是属半知菌纲,毛盘孢属,经离体培养,菌落粉红色,分生孢子椭园型。炭疽病是我省西瓜、甜瓜主要病害之一,一般年份都可发生,但因品种不同,栽培条件不一,发病率和危害程度差异性很大。我省主栽品种早花和蜜宝,每年均有发病,尤其老栽培区的县份,主栽品种是蜜宝,每年大面积发病,发病率高达100%,发病程度达到2—4级,果实发病率达30%,一般可减产30—50%。给瓜类生产带来很大危害。为了给抗病育种,抗病栽培,病害防治工作提出可靠的依据,经过2—3年的调查研究
Watermelon anthracnose is a semi-known Myceliophilia, Genus disc, by in vitro culture, colony pink, conidia elliptical. Anthracnose is one of the main diseases of watermelon and muskmelon in our province. It can occur in normal years. However, due to different varieties and different cultivation conditions, the incidence and the degree of harm are quite different. The main cultivars in our province are early flowering and honey treasures, and the incidence is high every year, especially in the old cultivation area. The main cultivars are the honey treasures, with large-scale incidence each year, the incidence is as high as 100%, the incidence is 2-4, and the fruit The incidence rate of 30%, generally reduce production by 30-50%. Gourd production to bring great harm. In order to disease-resistant breeding, disease-resistant cultivation, disease prevention and control work put forward a reliable basis, after 2-3 years of research
