草莓经济价值高,又适于我区种植,栽植面积日益扩大。但近年发现在浆果近成熟时常发生软腐霉烂,影响产量与品质。为此,进行了一些观察研究。 症状 此病仅危害浆果,多从果尖部开始,局部变色,继而伴有果汁外渗,迅速蔓延全果,并蔓延至果柄使之变褐。后期萎缩变干,形成红褐色僵果,在病果表面初见灰白色稀疏霉层,后渐呈鼠灰色,有时霉层覆 Strawberry high economic value, but also suitable for planting in our region, growing area planted.

Symptoms The disease is only damaging to berries.

Late shrinkage dry, the formation of reddish-brown stiff fruit in the diseased fruit surface saw gray sparse mildew layer, gradually after the mouse gray, and sometimes mold layer
