A field study was conducted in 2015 and 2016 at the H. Rouse Caffey Rice Research Station near Crowley, Louisiana, to evaluate the interactions of quizalofop and a mixture of propanil plus thiobencarb applied sequentially or mixed to control weedy rice and barnyardgrass. Visual weed control evaluations occurred at 14, 28, and 42 d after treatment (DAT). Quizalofop was applied at 120 g ai ha−1 at 7, 3, and 1 d before and after propanil plus thiobencarb were each applied at 3,360 g ai ha−1. In addition, quizalofop was applied alone and in a mixture with propanil plus thiobencarb at day 0. Control of red rice ‘CL-111’ and ‘CLXL-745’ was greater than 91% when quizalofop was applied alone at day 0, similar to control for quizalofop applied 7, 3, and 1 d prior to propanil plus thiobencarb at all evaluation dates. Control of the same weeds treated with quizalofop plus propanil plus thiobencarb applied in a mixture at day 0 was 70% to 76% at each evaluation date, similar to quizalofop applied 1 or 3 d after propanil plus thiobencarb. A similar trend in control of barnyardgrass by 88% to 97% occurred when quizalofop was applied alone and by 48% to 53% at 14, 28, and 42 DAT when the mixture was used. ‘PVL01’ rough rice yield was 4,060 kg ha−1 when treated with quizalofop alone; however, yield was reduced to 3,180 kg ha−1 when it was treated with quizalofop mixed with propanil plus thiobencarb at day 0, similar to PVL01 rice treated with quizalofop 1 or 3 d following the propanil plus thiobencarb application.

在乙酰辅酶A羧化酶抑制剂抗性水稻中序贯施用喹禾灵和丙胺加硫苯威的评价

2015 年和 2016 年在路易斯安那州克劳利附近的 H. Rouse Caffey 水稻研究站进行了一项实地研究，以评估喹草灵与异丙苯胺和硫苯威的混合物的相互作用，以控制杂草稻和稗草。视觉杂草控制评估发生在处理后 14、28 和 42 天 (DAT)。Quizalofop 以 120 g ai ha 施用-1在 3,360 g ai ha 之前和之后的 7、3 和 1 d-1. 此外，在第 0 天单独施用喹唑啉和与丙苯尼加硫苯威的混合物。当在第 0 天单独施用喹唑啉时，红米“CL-111”和“CLXL-745”的控制率大于 91%，类似于在所有评估日期，在异丙尼加硫苯威之前 7 天、3 天和 1 天应用喹唑草胺对照。在第 0 天以混合物形式施用的喹禾灵加苯菌灵加硫苯威威处理的相同杂草在每个评估日期的控制率为 70% 至 76%，类似于在禾灵灵加硫苯威灵后 1 或 3 天施用的喹禾灵。当单独使用喹草灵时，稗草的控制率出现了 88% 到 97% 的类似趋势，而当使用混合物时，在 14、28 和 42 DAT 时发生了 48% 到 53% 的趋势。'PVL01' 糙米产量为 4,060 公斤公顷-1当单独用喹唑啉治疗时；然而，产量减少到 3,180 公斤公顷-1当它在第 0 天用与敌草胺和硫虫威混合的喹草灵处理时，类似于在施用异虫腈和硫虫威后 1 天或 3 天用喹草灵处理 PVL01 大米。
