对保护地番茄灰霉病发生规律及防治进行了研究。结果表明 ,在相对湿度为 90 %以上的条件下 ,灰葡萄孢菌生长的适宜温度为 2 2～ 2 4℃ ;31℃以上高温对病原菌有抑制作用 ,低温高湿有利于病害发生。据此 ,采用生态防治、变温管理 ,在关键时期辅以高效烟剂为主的化学防治 ,可取得良好的防治效果。
The occurrence and prevention of tomato gray mold disease were studied. The results showed that the suitable temperature for the growth of Botrytis cinerea was 22 ~ 24 ℃ when the relative humidity was above 90%, and the pathogen was inhibited by high temperature above 31 ℃. Accordingly, the use of ecological control, temperature management, supplemented by high-level smoke in the key chemical-based chemical control, can achieve good control effect.
