摘要
为了筛选出对田间抗性杂草防除效果好、对小麦安全的高效除草剂,开展了多种除草剂及组合用药配方对麦田抗性杂草的防效研究。结果表明,不同类型除草剂通过土壤封闭处理和茎叶喷雾处理对麦田禾本科杂草和阔叶类杂草均有良好的防效,且对小麦安全。其中,土壤封闭处理效果较好的有33%吡氟酰草胺·呋草酮·氟噻草胺油悬浮剂、750 g/L环庚草醚乳油、33%特丁净·17%丙草胺·4%吡氟酰草胺油悬浮剂,茎叶喷雾处理效果较好的有107 g/L唑啉草酯·双氟磺草胺·氯氟吡氧乙酸异辛酯乳油+50 g/L唑啉草酯乳油+50%异丙隆可湿性粉剂、30 g/L甲基二磺隆油分散剂、11%双氟磺草胺·甲基二磺隆·炔草酯油分散剂+288 g/L氯氟吡氧乙酸异辛酯乳油、25%环吡氟草酮·异丙隆油分散剂+22%氟吡·双唑酮油分散剂。
In order to screen high-efficiency herbicides with good control effect on resistant weeds in the field and safety to wheat,the effects of various herbicides and combined formulas against resistant weeds in the wheat field were studied in this paper.The results showed that different types of herbicides all had good control effect on Gramineous weeds and broad-leaved weeds in wheat fields through soil closure treatment and stem-leaf spray treatment.Among them,33% pyrufluracylamine·furofurone·fluthiachlor OF,750 g/L cycloheptanoether EC and 33% tebujin·17% propachlor·4% pyrufenoxalide OF had better soil closure effect;107 g/L azolinoxate·difluorosulamine·chloroflupiroxy isooctyl EC+50 g/L azolinoxate EC+50% isopropyl WP,30g/L methyl disulfurone OD,11% difluorsulfurone·methyl disulfurone·acetylide OD+288 g/L clofluriroxy isooctyl EC,25%cyclopyfluroxone·isopropyl OD+22% fluriroxy·dizolone OD had better stem-leaf spray effect.
