摘要:

本试验选用36%二氯异噁草酮悬浮剂(封趣)、50%异丙隆悬浮剂(苏麦隆)、3.6%二磺·甲碘隆水分散粒剂(阔世玛)、55%吡酰·异丙隆悬浮剂(技除)等除草剂进行大麦田杂草防除,研究其防效及安全性。结果表明,技除对禾本科杂草防效最优,株防效和鲜重防效分别达67.9%和75.5%,且对大麦安全,增产8.9%;封趣及苏麦隆混用处理和阔世玛处理虽防效较好,但均引起药害导致减产;唑啉草酯与唑草酮混用处理及异丙隆单用处理防效不佳。本研究为江浙地区大麦田杂草科学防控提供了药剂选择依据。

Abstract:

In this experiment,herbicides including 36% diuron diflufenican suspension concentrate(Fengqu),50% isoproturon suspension concentrate(Sumailong),3.6% mesosulfuron-methyl & iodosulfuron-methyl sodium water-dispersible granule(Kuoshima),and 55% diflufenican & isoproturon suspension concentrate (Jichu)were selected for weed control in barley fields to evaluate their efficacy and safety. The results showed that Jichu exhibited the best control effect against the weeds of Gramineae,with plant control efficacy and fresh weight control efficacy reaching 67.9% and 75.5%,respectively. Moreover,it was safe for barley and increased yield by 8.9%. Although the mixed treatment of Fengqu and Sumailong as well as the Kuoshima treatment showed good weed control efficacy,both caused phytotoxicity and resulted in yield reduction. The mixed treatment of pinoxaden and carfentrazone-ethyl and the single application of isoproturon showed poor control efficacy. This study provides a basis for selecting appropriate herbicides for scientific weed control in barley fields in the Jiangsu-Zhejiang region.

Key words: barley, herbicide, safety, yield increase
