#月季白粉病

分布与危害

分布于四川、云南、江苏、浙江、江西、上海、北京、天津、青岛等地。以北京、重庆发病严重。

症状

病原

子囊菌门毡毛单囊壳Sphaerothecapannosa LeV

发生规律

病菌以菌丝体或闭囊壳在芽、叶或枝上越冬。翌年子囊孢子或分生孢子经风传播,从叶片气孔,幼嫩组织或直接侵入植物体。气温15℃时开始发病,17-25℃为发病适温,30℃以上发病较少;病菌对湿度适应范围很广,温暖潮湿季节发病迅速,5-6月和9-10月是发病盛期。土选育抗病品种。

防治方法

1.适当增施磷、钾肥。

2.合理施肥,避免氮肥过多,壤中氮肥过多或钾肥过少时易发病。

3.早春清除并烧毁病叶。

4.适度修剪,保持植株通风透光。

5.以预防为主,治疗为辅,可使用国光黑杀可湿性粉剂3000-4000倍液,国光三唑酮乳油1500-2000倍液叶面喷雾进行防治。
