DTY、ETS防除机插稻杂草效果及应用技术初探

Preliminary Study on Weed Control Effect and Application Technology of DTY and ETS in Rice Transplanting

摘要: 田间试验结果表明，供试的2个药剂在水稻机插后7 d即水稻返青后使用对稻田杂草有很好的防除效果，其中药后43 d：DTY 804 gai/hm²对禾本科草、阔叶杂草以及总草的株防效和鲜重防效分别为98.9%和99.1%、94.0%和94.9%以及95.1%和96.3%，ETS 849.5 gai/hm²分别为98.4%和98.7%、92.5%和93.8%以及93.8%和95.4%，均分别优于对照药剂50%苄嘧∙苯噻酰WP 450 gai/hm²，且安全性好。

Abstract: Field test results show that, the two pesticides tested had good control effect on weeds in paddy fields 7 days after rice machine transplantation. After rice greening, 43 days after treatment: DTY 804 gai/hm² had 98.9% and 99.1%, 94.0% and 94.9%, 95.1% and 96.3% plant and fresh weight control effects on grasses, broad-leaved weeds and total weeds, respectively, and ETS 849.5 gai/hm² were 98.4% and 98.7%, 92.5% and 93.8%, 93.8% and 95.4%, respectively. They were superior to 50% benzylpyrimidine benzothienyl WP 450 gai/hm², respectively. And the safety is good.
