摘要
为筛选出对葡萄灰霉病有良好防治效果的杀菌剂,文章根据形态学对葡萄灰霉病病原进行鉴定,并用菌丝生长速率法测定7种杀菌剂对葡萄灰霉病菌的室内毒力检测。结果表明,腐霉利、丙环唑、异菌脲、腈菌唑、咪鲜胺、代森锰锌和甲基硫菌灵对葡萄灰霉病菌的EC_(50)分别是9.629、23.630、23.830、93.460、318.300、344.400和1454.00μg/mL,因此在葡萄灰霉病的田间防治可将腐霉利、丙环唑和异菌脲药剂轮换使用。
To screen fungicides with good control effects against gray mold in Grape, pathogen of gray mold was identified by morphological characteristics, and indoor toxicity of seven fungicides against gray mold was determined by mycelium growth rate. The results showed that EC50 value of procymidone, propiconazole, iprodione, myclobutanil, prchloraz, mancozeb and thiophanate-methyl were different, respectively 9.629、23.630、23.830、93.460、318.300、344.400 and 1454.00 μg/mL. So three fungicides of procymidone, propiconazole and iprodione would be applied alternately to control against gray mold of Grape in field.
