番茄灰霉病发生与防治研究

Study on the Occurrence and Control of Tomato Gray Mold Disease

灰霉菌主要侵害番茄果实,在早春保护地中、下部果实发病较重;灰霉菌抱子萌发侵入除需适宜的温湿度条件外,还需一定的酸性条件和能量物质刺激;灰霉病发生的适宜温度18～24℃,相对湿度要求大于90%;防治上采取以生态控制为主,辅以带药蘸花,用烟雾法、粉尘法等进行综合治理。

The pathogen of gray mold disease mainly attacks flowers and fruits.In the early spring, lower fruits are infected seriously in the protective grounds;the spores can germinate and infect under preference temperature and humidity,combined with acid condition and energy material stimulation;the preference temperature for the disease to occur is 18～24℃,relative humidity exceeds 90 %;the main control method is ecological control,combined with dipping flowers with chemicals,smoking and dusting,etc.And the integrated control effect is better.
