Abstract

Field trials were conducted over a three-year period (2009 to 2011) to evaluate the efficacy of pendimethalin preplant-incorporated (PPI), bentazon, fomesafen, bentazon plus fomesafen, or halosulfuron applied postemergence (POST) and the sequential application of pendimethalin applied PPI followed by bentazon, fomesafen, bentazon plus fo- mesafen or halosulfuron applied POST in white bean in Ontario. There was minimal effect on seed moisture content of white bean with the herbicides evaluated. Pendimethalin provided 97% control of A. retroflexus, 9% of A. artemisiifolia, 90% of C. album, 12% of S. arvensis, and 96% of S.viridis. Bentazon, fomesafen, bentazon plus fomesafen, and halosul- furon applied POST provided as much as 93% control of A. retroflexus, 86% control of A. artemisiifolia, 72% control of C. album, 99% control of S. arvensis, and 29% control of S. viridis. The sequential application of pendimethalin applied PPI followed by bentazon, fomesafen, bentazon plus fomesafen, and halosulfuron applied POST provided 100% control of A. retroflexus, 87% control of A. artemisiifolia, 90% control of C. album, 100% control of S. arvensis, and 95% control of S.viridis, respectively. White bean yield generally reflected the level of weed control.

播前施戊二甲基灵，苗期后施阔叶除草剂防治白豆杂草

2009年至2011年进行了为期3年的田间试验，以评估在安大略省的白豆上施用苯二甲基林(PPI)、苯他松、氟美沙芬、苯他松加氟美沙芬或卤代磺隆(POST)后施用苯二甲基林(PPI)、苯他松、氟美沙芬、苯他松加氟美沙芬或卤代磺隆后依次施用苯二甲基林、苯他松、氟美沙芬或卤代磺隆后的效果。各除草剂对白豆种子含水量的影响不大。二甲醚对逆行蒿97%、蒿9%、金曲蒿90%、黄曲蒿12%、绿曲蒿96%的防效。喷施苯他松、氟美沙芬、苯他松加氟美沙芬和氟唑呋隆后，对逆行蚜的防治效果分别为93%、86%、72%、99%和29%。pendimethalin应用的顺序应用PPI其次是浙江大学,fomesafen,加上fomesafen,浙江大学和halosulfuron应用文章提供了100%的控制a . retroflexus 87%控制的a . artemisiifolia 90%控制c .专辑100% s .薄荷的控制,分别和95% S.viridis的控制。白豆产量总体上反映了杂草控制水平。
