摘要:

为提高麦田杂草化除效果,探明其安全性和除草效果,在小麦三叶一心(即优势种杂草看麦娘两叶一心)期开展了施用唑啉草酯及其多元混剂等不同茎叶处理除草剂对麦田杂草效果的防治效果试验。结果表明,在以单子叶杂草看麦娘为绝对优势杂草种群的麦田人工喷雾处理的效果优于飞防处理。其中,施用5%唑啉草酯乳油(2 250 mL·hm-2),对看麦娘60 d的株防效和鲜重防效100.00%,对杂草种群总体防治效果达90.00%以上;施用107 g·L-1唑啉草酯三元预混剂乳油(1 950 mL·hm-2)或5%唑啉草酯乳油(1 500 mL·hm-2)+200 g·L-1氯氟吡氧乙酸乳油(900 mL·hm-2),其对杂草种群的防效均可达到95.00%以上;而精噁唑禾草灵处理对试验地看麦娘种群总体处于低效或负效状态,因此,在以看麦娘为优势杂草种群的麦田中,不建议选用精噁唑禾草灵作为茎叶处理化除药剂。

Abstract:

To improve the effectiveness of weed control in wheat fields and to determine its safety and weed control effects, a comparative experiment on the effect of different stem and leaf herbicides treatments for controlling weeds in wheat fields was conducted during the 3-leaf and 1-heart stage of wheat (when the dominant weed species, Alopecurus aequalis, is at the 2-leaf and 1-heart stage). The results showed that the control effect of manual spray treatment was superior to that of aerial spray treatment. When 5% azolinoxin emulsified oil (2 250 mL·hm-2) was applied in the wheat field where the absolute dominant weed population was Alopecurus aequalis, its plant control effect and fresh weight control effect against Alopecurus aequalis for 60 days was 100.00%, and the overall control effect against the weed population was over 90.00%. And the plant control effect and fresh weight control effect against the weed population of 107 g·L-1 pinoxaden triple pre-mix emulsifiable concentrate(1 950 mL·hm-2) or a combination of 5% pinoxaden emulsifiable concentrate(1 500 mL·hm-2)+200 g·L-1 fluroxypyr emulsifiable concentrate(900 mL·hm-2) was over 95.00% weed control effect. In contrast, the application of fenoxaprop-P-ethyl provided low or negative effect against the Alopecurus aequalis population in the test field, and it is not recommended for application as a stem and leaf treatment herbicide in wheat fields dominated by Alopecurus aequalis.
