Abstract

Field studies were conducted during 2019 growing season in north-central, south-central, and the Coastal Bend areas of Texas to evaluate indaziflam herbicide systems for southern sandbur control and Coastal bermudagrass tolerance. Indaziflam caused no bermudagrass stunting at any location when applied preemergence (PRE) at 0.04 to 0.07 kg ai ha-1. Glyphosate at 0.35 kg ae ha-1 caused bermudagrass stunting which ranged from 16 to 65% when evaluated 3 to 5 weeks after application; however, when evaluated at the end of the growing season, no bermudagrass stunting was evident when compared with the untreated check. Southern sandbur control with indaziflam, when evaluated 28 to 32 weeks after the initial indaziflam PRE application, ranged from 85 to 99% in north-central Texas, 65 to 95% in south-central Texas, and 95 to 100% in the Coastal Bend region. Southern sandbur control with pendimethalin PRE system ranged from 74 to 100%, 11 to 85%, and 100% in those regions, respectively. Indaziflam represents a safe option for forage and hay producers in Texas to control southern sandbur.

南沙伯(Cenchrus echinatus L.)吲哚吡喃除草剂系统对百慕大草牧场的防治作用

2019年生长季，在德克萨斯州中北部、中南部和Coastal Bend地区进行了实地研究，以评估吲哚氟兰除草剂系统对南部沙伯的控制和沿海百慕大草的耐受性。在萌芽前0.04 ~ 0.07 kg / hm -1施用吲哚氟胺时，在任何位置均未引起百慕大草发育迟缓。草甘膦用量为0.35 kg / hm -1时，在施用后3 - 5周进行评估时，造成百慕大草发育迟缓的比例为16%至65%;然而，当在生长季节结束时进行评估时，与未经处理的检查相比，没有明显的百慕大草发育迟缓。在首次使用indaziflam PRE 28 - 32周后评估，在德克萨斯州中北部使用indaziflam控制南部沙虫的效果为85% - 99%，在德克萨斯州中南部为65% - 95%，在Coastal Bend地区为95% - 100%。在这些地区，喷二甲醚PRE系统对南方沙虫的防治效果分别为74% ~ 100%、11% ~ 85%和100%。对于德克萨斯州的饲料和干草生产商来说，Indaziflam是控制南部沙伯的安全选择。
