[目的]54%噻苯·敌草隆SC分别与伴宝、黑森、速捷3种喷雾助剂配合使用,评价其田间药效和安全性。[结果]施药处理1~4的棉花脱叶率和吐絮率分别为90%和80%左右,高于空白对照;施药处理1~4的棉花纤维长度和中、下部单铃重与空白对照基本相当,上部棉桃单铃重和小区产量比空白对照稍低;施药处理1~4间棉株的纤维长度、单铃重和小区产量基本相当。[结论]施用添加喷雾助剂的54%噻苯·敌草隆SC能有效提高棉花脱叶率和吐絮率,3种喷雾助剂对54%噻苯·敌草隆SC的活性和安全性基本相当;450、675 mL/hm2剂量下的喷雾助剂速捷对54%噻苯·敌草隆SC的活性和安全性差异不明显,因此综合考虑活性、安全性和经济性等因素,速捷可以替代另外2种助剂与54%噻苯·敌草隆SC配合使用,推荐田间施用剂量为450 mL/hm2。
[Objective] The study aimed to evaluate the efficacy and safety of 54% thiophene diuron SC in combination with Spray, Hesse and Quickjet Spray Additives. [Result] The percentage of cotton defloculation and spit plugging in treatment 1 ~ 4 was 90% and 80% respectively, which was higher than that of blank control. The length of cotton fiber and the boll weight and blank The results showed that the boll weight and plot yield of the upper boll was slightly lower than that of the blank control. The fiber length, boll weight and yield of the plots between 1 and 4 cotton bolls were basically the same. [Conclusion] The application of 54% thiabendazole and diuron SC supplemented with spray adjuvant could effectively improve the rate of leaf removal and the rate of boll opening. The activity and safety of 54% thiophene diuron SC with 3 kinds of spray auxiliaries The results showed that there was no significant difference in the activity and safety of 54% thiophene diuron SC at 450 and 675 mL / hm2 dose. The combination of agitation speed, safety and economic efficiency, It can be used in combination with 54% thiophene diuron SC instead of the other two auxiliaries. The recommended field dose is 450 mL / hm2.
