黄瓜枯萎病(萎蔫病、蔓割病)是黄瓜温室、大棚栽培中主要病害,常年发病率10％～30％,严重可达50％。目前在生产上防治黄瓜枯萎病,多采用化学药剂进行防治,一般效果不够理想。最近吉林农校李恩彪等用高锰酸钾防治枯萎病取得了明显的效果,用800倍、1000倍、1500倍液灌根,和双效灵300倍、敌克松800倍作比较,结果高锰酸钾800～1000倍灌根区无发病株,双效灵和敌克松防治区发病率分别为9.51％和23.31％,且株高明显高于对照区。用高锰酸钾防
Cucumber wilt (wilt disease, vine cut) is a cucumber greenhouse, greenhouse cultivation of major diseases, perennial incidence of 10% to 30%, a serious up to 50%. Currently in the production of cucumber blight prevention and control, more use of chemical agents for prevention and treatment, the general effect is not ideal. Recently Li Ningbiao, Jilin Agricultural School and other potassium permanganate wilt control achieved significant results, with 800 times, 1000 times, 1500 times irrigation, and double effective 300 times, compared with 800 times the enemy Kesi for comparison, the results of high There was no disease in 800-1000 times of irrigated root zone, and the incidence rates of Shuanglingling and Nixon were 9.51% and 23.31%, respectively, and the plant height was significantly higher than that in control area. Use potassium permanganate to prevent
