1.根结线虫病线虫侵入幼苗根部,形成许多瘤状物,导致细根肥肿、腐败而破裂,地上部分枯死。防治方法:(1)播种和移栽前两周,用滴滴混剂原液熏蒸土壤,每平方米用5～8毫升。(2)发病后用80％敌敌畏1000倍液浇灌根际土壤。2.孢囊线虫病线虫侵入幼苗根部,形成许多大小不等的虫瘿,严重时细根变褐腐烂,叶片枯黄而死。防治方法与根结线虫病相同。
Root-knot nematode nematodes invade seedling roots, the formation of many tumor-like, resulting in fine root swollen, rupture of corruption, the ground part of the withered. Control methods: (1) Two weeks before sowing and transplanting, fumigating the soil with a drop of liquid mixture, with 5 to 8 ml per square meter. (2) after the onset of water with 1000% dichlorvos 80% water irrigated rhizosphere soil. 2. Cyst nematode Nematodes invade seedling root, forming many sizes of insects, severe fine roots become brown rot, leaves withered and dead. Control methods and root knot nematodes the same.
