种衣剂对青稞病虫害防治效果及产量的影响

Effects of seed coating agents on diseases control and yield in highland barley

为了探究种衣剂种类与浓度对青稞蚜虫和黑穗病的防治效果,每百千克种子分别用酷拉斯350ml(27%含量)、酷拉斯450ml(27%含量)、敌委丹350ml(3%含量)、敌委丹450ml(3%含量)以及卫福350ml(40%含量)进行拌种,以清水350ml拌种为对照(CK)。研究结果表明,不同浓度酷拉斯处理对蚜虫的防治效果达到84%~97%,每百千克种子酷拉斯450ml处理对黑穗病的防治效果达到98.4%,每百千克种子酷拉斯350ml处理的小区产量增产效果最明显,对比照增产15.6%。研究表明酷拉斯种衣剂是非常有潜力的青稞蚜虫和青稞黑穗病抑制剂,可在西藏自治区农业生产实践中进行推广应用。

In order to explore the control effect of seed coating agent on barley aphids and smut,we used 350 ml of Cruiser Max(27%),450 ml of Cruiser Max(27%),350 ml of Dichlorfon(3%),450 ml of Dichlorfon(3%)and 350 ml of Weifu(40%)per 100 kilogram of seeds to treat the seeds,and used 350 ml water as a control.The results showed that the control effect of different concentrations of Cruiser Max on aphids was 84%-97%,the control effect of Cruiser Max with 450 ml·(100 kg)^-1 seed on smut reached 98.4%,and Cruiser Max with 350 ml·(100 kg)^-1 seed on plot yield increased by 15.6%compared with control.Cruiser Max seed coating agent is a potential inhibitor on barley aphids and smut,and can be widely applied in agricultural production in Tibet.
