用敌磺钠、硫酸铜、多菌灵和代森锰锌4种杀菌剂不同浓度进行油菜根肿病防效试验。结果表明,4种药剂均有一定防病效果,尤以50%多菌灵WP的防效最好,且药剂浓度越高的防效越好,防效越好的油菜产量越高。药剂防病的保产作用,是发病株率减少和病株病情减轻的结果。 Four different fungicides, sodium sulfonate, copper sulfate, carbendazim and mancozeb, were used to control the root edema disease in rapeseed. The results showed that all four agents had certain disease control effect, especially 50% carbendazim WP had the best control effect. The higher the drug concentration, the better the control effect and the higher the yield of rape. Preventive effects of pesticides, is the incidence of reduced plant disease and disease mitigation results.
