摘要
为筛选出有效控制红菜苔根肿病发生且安全性高的杀菌剂,以苗期和成株期的安全性、发病率、病情指数为评价指标,比较了8种杀菌剂的田间防治效果。结果表明,81%甲霜·百菌清WP、75%异菌·多·锰锌WP、69%烯酰·锰锌WP对红菜苔根肿病苗期防效分别达97.41%、100%、97.18%,成株期防效分别达96.80%、99.65%、97.33%,且均无药害,可用于田间防治红菜苔根肿病。
In order to select the safety and effect fungicides to fungicides against the clubroot of Brassica campestris L. var. purp control clubroot,the study urea by field trial, use safe ev aluated disease performances of 8 dence and disease index in seeding stage and adult stage as evaluation indexes. The results showed that the control effect of Chlorothalonil WP,75% Iprodione Carbendazim 100% ,97. 18% in seeding stage,while were 96. at all. The study proved that the three fungicides control clubfoot in field. Mancozeb WP and 69% Dimethomorph Mancozeb 80% ,99.65% ,97.33% in adult stage,and they all have high and stable control effect against clubfoot WP had , they 81% Metalaxyl were 97.41% , no phytotoxicity can be used to
