近年来,中国农科院蔬菜花卉所研究了我国具有自主知识产权的新型化合物氟唑活化酯诱导大白菜对根肿病的抗病效果及诱导技术。荧光染色观察发现,该化合物对根肿菌休眠孢子没有明显的杀死作用,但具有明显的诱导抗病效果。不同的诱导浓度、诱导间隔期和诱导次数对根肿病的诱抗效果均不同。温室盆栽试验结果显示,25mg/L的氟唑活化酯间隔7天诱导大白菜3次,对根肿
In recent years, the Chinese Academy of Agricultural Sciences, vegetable and flower research of our country with independent intellectual property rights of new compounds fluconazole activated ester cabbage induced clubroot disease resistance effect and induction technology. Fluorescent staining showed that the compound had no significant killing effect on the resting spores of R. solani, but had obvious anti-disease effect. Different inducing concentrations, induction interval and induction times had different inducing effects on clubroot disease. The result of pot experiment in greenhouse showed that 25 mg / L flurazole activated ester induces Chinese cabbage three times every 7 days,
