摘　　要：助剂DK8是我国企业开发的一种农药助剂,本文研究了助剂DK8对杀菌剂可湿性粉剂(WP)性能的提高作用,助剂DK8可以显著提高杀菌剂可湿性粉剂的悬浮率,降低润湿时间。活体组织法实验表明添加5%的DK8可提高福美双、菌核净、戊唑醇可湿性粉剂对油菜菌核病的防治效果。田间试验结果表明助剂DK8对菌核净防治油菜菌核病也有一定的促进作用。Pesticide adjuvant DK8 was developed by a Chinese agrochemical enterprise.The improving effects of adjuvant DK8 on fungicide wettable powder （WP） were studied and results showed that DK8 could significantly increase suspension rate and decrease wetting time of fungicide WP.Studies on detached leaves of oilseed rape in laboratory showed that 5％ of DK8 could improve controlling effects of thiram,dimethachlon and tebuconazole on Sclerotinia sclerotiorum.Field experiments results indicated that DK8 was conductive to efficacy of dimethachlon against S.sclerotiorum.
