19种杀菌剂对黑皮冬瓜疫病病菌室内毒力测定

Determination of indoor toxicities of 19 fungicides against phytophthora blight pathogen in black wax gourd

为筛选防治黑皮冬瓜疫病的高效药剂,进行19种常见商品杀菌剂对黑皮冬瓜疫病病菌的室内毒力测定,结果表明,50%安克可湿性粉剂和50%施得益可湿性粉剂的毒力最强,对黑皮冬瓜疫病病原菌的生长抑制率分别为89.36%和87.43%,其余为72%克露可溶性粉剂53.07%、68%金雷多米尔水分散粒剂51.43%,这几种杀菌剂可直接在生产中使用。

In order to screen high-effective medicaments, 19 fungicides against phytophthora blight in black wax gourd that are common at home and abroad were used to carry out the determination of indoor toxicities. The results showed that dimethomorph and flumorph-mancozeb had the highest growth inhibition rates（89.36% and 87.43%, repectively） against the pathogen. The inhibition rates of curzate,ridomil were 53.07% and 51.43%, respectively. The above fungicides could directly apply in commercial production.
