| 摘 要： | 瓜类白粉病是蔬菜上的重要病害之一,为加大对该病害的生物防治力度,本研究采用课题组研发的1×109cfu/g玫瑰黄链霉菌水剂和10亿芽胞/g枯草芽胞杆菌悬浮剂以及市场上常用的枯草芽胞杆菌、哈茨木霉菌、寡雄腐霉、武夷菌素、多抗霉素等多种生物制剂进行田间药效试验,比较几种生物制剂的防治效果。结果表明,供试生物制剂对西葫芦白粉病的防效为57.65%~84.98%,其中3%多抗霉素水剂600倍液的防效最好,为84.98%,且具有明显的促生长作用,增产率达12.65%。其次为1 000亿芽胞/g枯草芽胞杆菌可湿性粉剂(武汉天惠)400倍液、2%武夷菌素水剂600倍液和3×108 cfu/g哈茨木霉菌可湿性粉剂300倍液,可作为西葫芦白粉病防治的选用药剂。1×109 cfu/g玫瑰黄链霉菌水剂对西葫芦和黄瓜白粉病均具有较好的防效,分别为78.68%和73.59%,具有开发和应用的市场价值。

| Abstract: | Cucurbits powdery mildew was recorded as one of the serious diseases on vegetables. In order to effectively control cucurbits powdery mildew, 1×109 cfu/g Streptomyces roseoflavus AS, 1×109spores/g Bacillus subtilis SC developed by our laboratory and the biological fungicides used commonly on the market, including B.subtilis, Trichoderma harzianum, Pythium oligadrum, wuyiencin and polyoxin, were tested in the field. The results showed that the control efficacies of these biological fungicides were 57.65%-84.98%. The effect of the 600 times dilution of 3% polyoxin AS was best (up to 84.98%), with the ability to promote growth of summer squash. 1×1011 spores/g B.subtilis WP 400 times (Wuhan Tianhui), 2% wuyiencin AS 600 times and 3×108 cfu/g T.harzianum WP 300 times could also be used for the control of summer squash powdery mildew. 1×109 cfu/g S.roseoflavus AS showed good therapeutic activity against summer squash and cucumber powdery mildew, with a control efficacy of 78.68% and 73.59%, respectively. Therefore, 1×109 cfu/g S.roseoflavus AS has a good value for application and a prospect for market development |
