is a problematic weed in mungbean crops due to its high seed production, resistance to glyphosate and high dispersal ability. Pot and field experiments were conducted in 2020 and 2021 to evaluate a range of preemergent (PRE) herbicides for control in mungbean. In the field and pot studies, isoxaflutole 75 g ai ha caused crop injury, and in the field experiment, it reduced mungbean yield by 61% compared with the best treatment (pyroxasulfone 100 g ai ha). In the field and pot experiments, dimethenamid-P 720 g ai ha, pyroxasulfone 100 g ai ha and S-metolachlor 1400 g ai ha provided >88% control of (for reduced biomass) and in the field experiment, these herbicides resulted in improved yield by 230%, 270% and 170%, respectively, compared with nontreated control (250 kg ha). Similarly, pendimethalin 1000 g ai ha and trifluralin 600 g ai ha provided >89% control (biomass) of and in the field experiment, these resulted in improved yields of 230% and 160%, respectively, compared with the nontreated control. PRE herbicides such as diuron 750 g ai ha, linuron 1100 g ai ha, metribuzin 360 g ha, terbuthylazine 750 g ai ha, imazapic 48 g ai ha and imazethapyr 70 g ha although did not cause crop injury; however, these herbicides did not control . Flumioxazin 90 g ai ha caused reduced biomass of by 80% compared with the nontreated control, and in the field experiment, it resulted in improved yield by 140% compared with the nontreated control. This study suggests the potential use of herbicides, such as dimethenamid-P, pyroxasulfone and S-metolachlor in addition to pendimethalin and trifluralin, for control in mungbean. Further studies are needed to determine the efficacy of dimethenamid-P, S-metolachlor and pyroxasulfone for controlling other troublesome weeds in mungbean.
由于其高种子产量、对草甘膦的抗性和高传播能力，它是绿豆作物中的一种有问题的杂草。在2020年和2021年进行了盆栽和田间试验，以评估一系列苗前（PRE）除草剂对绿豆中该杂草的防除效果。在田间和盆栽研究中，异恶唑草酮75克有效成分/公顷造成了作物损伤，并且在田间试验中，与最佳处理（唑吡嘧磺隆100克有效成分/公顷）相比，它使绿豆产量降低了61%。在田间和盆栽试验中，二甲戊灵720克有效成分/公顷、唑吡嘧磺隆100克有效成分/公顷和异丙甲草胺1400克有效成分/公顷对该杂草的防除效果>88%（以减少生物量计），并且在田间试验中，与未处理对照（250千克/公顷）相比，这些除草剂分别使产量提高了230%、270%和170%。同样，二甲戊灵1000克有效成分/公顷和氟乐灵600克有效成分/公顷对该杂草的防除效果>89%（以生物量计），并且在田间试验中，与未处理对照相比，它们分别使产量提高了230%和160%。苗前除草剂如敌草隆750克有效成分/公顷、利谷隆1100克有效成分/公顷、嗪草酮360克/公顷、特丁津750克有效成分/公顷、咪唑乙烟酸48克有效成分/公顷和咪唑喹啉酸70克有效成分/公顷虽然未造成作物损伤；然而，这些除草剂并未防除该杂草。与未处理对照相比，氟唑磺隆90克有效成分/公顷使该杂草的生物量减少了80%，并且在田间试验中，与未处理对照相比，它使产量提高了140%。这项研究表明，除了二甲戊灵和氟乐灵外，除草剂如二甲戊灵、唑吡嘧磺隆和异丙甲草胺在绿豆中防除该杂草方面具有潜在用途。需要进一步研究来确定二甲戊灵、异丙甲草胺和唑吡嘧磺隆对控制绿豆中其他棘手杂草的效果。
