4种除草剂对夏玉米田杂草及麦苗的防效与安全性比较

为筛选出对夏玉米田杂草及自生麦苗的防效及安全性较好的除草剂,选用4种莠去津复配剂进行玉米田杂草防除效果及安全性研究。结果表明:31.5%噻酮磺隆.异噁唑草酮+38%莠去津总杂草株防效为88.7%,鲜质量防效为98.48%,防效较好,无明显药害症状,且产量为各药剂处理中最高;22%烟嘧.莠去津和30%苯唑草酮+助剂+38%莠去津对自生麦苗株防效均在80%以上,鲜质量防效在95%以上,但30%苯唑草酮+助剂+38%莠去津对莎草的株防效仅45.58%,莎草为主的夏玉米田块不建议使用。 英文摘要: In order to screen out the safe and effective herbicide against weeds and wheat seedlings in summer corn field, field experiments were carried out on 4 atrazine-containing formulations. The results show that the 31.5% thiazone metsulfuron.isoxazol clomazone +38% atrazine weed control and safety were better than other treatments, and the yield was the highest in all treatments. 22% nicosulfuron.atrazine and and 30% topramezone +adjuvants +38% atrazine on spontaneous wheat plant control effect were above 80%, fresh quality control efficiency in more than 95%, but 30% topramezone +adjuvants +38% atrazine on sedge control effect was 45.58%, not recommended for use in summer corn field which have a lot of sedge. 查看全文
