摘要
从甜瓜病果上分离出的尖孢镰刀菌甜瓜专化型能够侵染网纹甜瓜幼苗,病苗表现为子叶黄化,顶端失水萎蔫,根茎部变黄褐色。药剂处理土壤以五氯硝基苯+多菌灵防治效果较好。
F.oxysporum f.sp.melonis isolated from diseased fruit can infect the seedling of cucumis melo var. reticulates. The cotyledon of diseased plant is yellowing, the top of diseased plant is losing water and wilting, and its rhizome becomes yellowish brown. The effect of quintozene and carbendazim on F.oxysporcum f.sp.melonis is better than others when treating soil with fungicides.
