| 摘 要： | 为明确新型水直播稻田除草剂精噁唑甘草胺以及对照药剂对于直播稻田禾本科杂草的防除效果以及对于水稻及后茬作物的安全性, 于2019年在江西宜春市上高县水稻田进行了大田杂草防效试验以及后茬作物安全性研究。结果表明:8%精噁唑甘草胺OD对于直播水稻田的禾本科杂草具有良好的防除效果, 120 g/hm2 以及200 g/hm2 剂量处理对于禾本科杂草的防效均在88%以上。而且所有处理对于水稻均无药害产生, 实现增产, 并对后茬作物生长安全。综上所述, 新型直播稻田除草剂精噁唑甘草胺对直播水稻田禾本科杂草有良好防除效果, 可以在市场上推广应用。

| Abstract: | In order to clarify control effect of glyamifop, a new type of herbicide, and its control agent on gramineous weeds in direct seeding paddy field and its safety on rice and subsequent crops, field weed control experiments and safety experiments on subsequent crops were conducted in Shanggao paddy field in Yichun city, Jiangxi province in 2019.The results showed that glyamifop 8% OD had a good control effect on weeds in direct seeding rice fields. The control efficacies of glyamifop at 120 g/hm2 and 200 g/hm2 on gramineous weeds were both above 88%. In addition, all treatments had no phytotoxicity to rice and increased rice yield, and were safe to subsequent crops. In summary, the new herbicide glyamifop has good control effect on gramineae weeds in direct seeding rice field, which can be promoted and applied in the market. |
