当前小麦阔叶除草剂品种繁多,各种除草剂防除麦田阔叶杂草效果差异较大。氯氟吡氧乙酸等几种麦田阔叶除草剂药效试验表明:200.0g/L氯氟吡氧乙酸在施药后30d,鲜质量防效和株防效分别达到78.4%和83.0%,持效期长,杀草彻底;56%二甲四氯钠+75%苯磺隆不同用药量和用水量以56%二甲四氯钠30.0g/667m2+75%苯磺隆1.5g/667m2对水30.0kg/667m2防效最高。建议:在以猪殃殃、婆婆纳等恶性杂草为主的麦田选用200.0g/L氯氟吡氧乙酸;在以播娘蒿、荠菜、遏蓝菜等杂草为主麦田,选用56%二甲四氯钠+75%苯磺隆。另外为避免杂草产生抗药性,56%二甲四氯钠+75%苯磺隆、22%唑草酮+14%苯磺隆、40%唑草酮+10%苯磺隆可交互使用。
At present, there are many varieties of broad-leaved wheat herbicides, and the effect of various herbicides on the control of broad-leaved weeds in wheat fields is quite different. Fluvastatin and other several broad-leaved wheat field herbicide efficacy tests showed that: 200.0g / L fluropenthapyr 30 d after application, the fresh quality control effect and strain control efficiency reached 78.4% and 83.0%, respectively, with 56% sodium dimethylchlorosilane + 75% tribenuron-methyl different dosage and water consumption to 56% dimethylchloro sodium 30.0g / 667m2 + 75% tribenuron-methyl 1.5g / 667m2 Water 30.0kg / 667m2 highest control efficiency. Suggestion: Choose 200.0g / L fluroxypyr in wheat field such as Galium apocynum, Veronica and other malignant weeds; choose wheat with 56% Dimethyl sodium chloride + 75% tribenuron-methyl. In addition, in order to prevent the weeds from developing drug resistance, 56% dimethylchlorosilane + 75% tribenuron-methyl, 22% meconazole + 14% tribenuron-methyl, 40% meconazole + 10% tribenuron-methyl can be used interchangeably.
