摘　　要：对不同地区的葡萄灰霉病进行调查和采样 ,根据病害症状、病原形态和寄主范围对葡萄灰霉病进行鉴定 ,结果表明 ,该葡萄灰霉病菌为灰葡萄孢菌 (BotrytiscinereaPers .)。该菌的生长温度范围是 5～ 30℃ ,最适温度为 15～2 5℃ ;生长的pH值范围是 2～ 9,最适为 3～ 6 ;光照条件对病菌的生长基本无影响 ;该菌的寄主范围广泛 ;木纳格和巨峰对葡萄灰霉病的抗性较强 ;甲基硫菌灵、亿嘉乐对葡萄灰霉病菌的抑制效果较好。The writer investigated and sampled grape grey mold in different regions of Xinjiang.According to its symptom,morphologic characters,cultural characteristics, host range,it was shown that the pathogen was Botrytis cinerea Pers.The temperature for this pathogen growth was from 5℃ to 30℃,with the optimum from 15℃ to 25℃;the pH values ranged from 2 to 9,with the optimum from 3 to 6;the different light had no significant effect on mycelial growth;this pathogen had wide range of hosts;Munage and Jufeng had high resistance to Botrytis cinerea;Thiophanate-methyl and Yijiale significantly inhibited the pathogen growth.
