摘要：

为了规范麦田科学用药,探究常用茎叶除草剂对江苏沿海地区麦田禾本科杂草的防除效果,整理了用于麦田禾本科杂草茎叶化除的登记性除草剂,通过田间药效试验探究11个除草剂处理对麦田禾本科杂草的防除效果。结果表明：炔草酯在登记用量内单独使用株防效只有17.98%,异丙隆提高25%登记用量株防效为63.17%,炔草酯与异丙隆混用和复配在不同剂量下的株防效为55.58%~89.99%,啶磺草胺与炔草酯混用的株防效为56.68%,甲基二磺隆与异丙隆混用的株防效为63.7%,唑啉草酯登记用量下株防效只有47.38%,但鲜重防效为80.46%,环吡氟草酮作为新型除草剂对禾本科杂草株防效可达99.05%。由此得出,除草剂需进行复配使用增加防效延缓抗性,加大推广环吡氟草酮等高效低抗新型除草剂,同时对陈旧除草剂登记信息进行更新以更好地指导用药。

Abstract:

The objective is to regulate the scientific use of herbicides in wheat fields, and to investigate the control effect of common stem and leaf herbicides on the weeds in wheat fields in the coastal areas of Jiangsu Province. The registered herbicides used for stem and leaf removal in the weeds in wheat fields were sorted out, and the control effects of 11 herbicides on weeds in wheat fields were investigated through field efficacy trial. The results showed that within the dosage of registration, the control effect with clodinafop-propargyl alone was only 17.98%, isoproturon increased 25% dosage of registration had control effect of 63.17%, clodinafop-propargyl compounded with isoproturon provided control effect from 55.58% to 89.99% under different doses, pyroxsulam compounded with Clodinafop-propargyl provided control effect of 56.68%, mesosulfuron compounded with isoproturon provided control effect of 63.7%. Within the registered dosage, azoline oxalate had only control effect of 47.38%, but the control effect of fresh weight was 80.46%. As a new herbicide, the control effect of cyclopyrazorone on grass weeds was 99.05%. The conclusion is that herbicides should be compounded to improve the control effect and delay the resistance effect, new herbicides with high efficiency and low resistance such as cyclohexanone should be promoted, meanwhile the registration information of old herbicides should be updated for the better use of pesticide.
