近年来,我市草莓面积不断扩大,草莓菌核病呈逐年加重的趋势。1998年,全市发病面积超过133.3hm~2,一般病株率在50%左右,最高的达95%以上,直接经济损失在4成以上,严重影响了产量和品质,制约了草莓生产的发展。为此,笔者于1996～1998年对草莓菌核病进行了调查研究,基本摸清了该病的发生规律与防治方法。现报道如下。
In recent years, the area of strawberry in our city continues to expand, and the incidence of strawberry sclerotinia is increasing year by year. In 1998, the disease area in the whole city exceeded 133.3hm ~ 2, the average diseased plant rate was about 50%, the highest reached more than 95% and the direct economic loss was over 40%, seriously affecting the yield and quality and restricting the development of strawberry production.
