摘要
筛选出了50%啶酰菌胺可湿性粉剂(WP)的优化配方(质量比)为啶酰菌胺50.0%、十二烷基苯磺酸钠3.0%、木质素磺酸钠3.0%、助剂DK8 5.0%,硅藻土补足100.0%,按此配方制得质量合格的50%啶酰菌胺WP,用其进行田间防效试验,结果表明,50%啶酰菌胺WP 247.5~322.5 g(a.i)/hm^2对油菜菌核病(Sclerotinia sclerotiorum)的防效达到67.5%~80.1%,优于对照药剂50%多菌灵WP 750.0 g(a.i)/hm^2(防效66.2%)、40%菌核净WP 375.0 g(a.i)/hm^2(防效64.9%),且对油菜安全.
The formulation of Boscalid wettable powder (WP) was optimized with Boscalid 50.0%,sodium do-decylbenzene sulfonate 3.0%,sodium lignosulfonate 3.0%,adjuvant DK8 5.0%.Field efficacy of 50.0% Boscalid WP at 16.5~21.5 g (a.i)/667 m^2 against Sclerotinia sclerotiorum reached 67.5%~80.1% whereas that of the control with fungicide 50% Carbendazim WP 50.0 g (a.i)/667m^2 was 66.2%,and of 40% Dimethachlon WP 20.0g (a.i)/667m^2 was 64.9%.It is indicated that the 50% Bosealid WP developed is safe for rapeseed plant.
