通过田间小区试验,测定了55%苯·唑·二甲钠WP的除草效果、对小麦及后茬作物的安全性。结果表明,55%苯.唑.二甲钠WP在施用剂量为330.0、412.5、495.0、825.0 g a.i./hm2时,对猪殃殃、播娘蒿、荠菜等小麦田阔叶杂草均有很好的防除效果,药后30 d总杂草鲜重防效为95.4%~99.0%,对小麦的安全性较好,小麦增产12.2%~14.5%,对后茬作物大豆、花生、玉米安全性很好,无残留药害。 Field trials were conducted to determine the herbicidal effect of WP, 55% WP, on the safety of wheat and its subsequent crops. The results showed that broad-leaved weeds of 55% benzole azole and dimethylsulfate WP in wheat field such as Galium aparifolium, Artemisia selengensis and Capsella bursa were effective at the application rates of 330.0, 412.5, 495.0 and 825.0 g ai / hm2 Good control effect, the control effect of total fresh weight of weeds was 95.4% -99.0% on the 30th day after treatment, the safety to wheat was better, the yield of wheat increased 12.2% -14.5%, the safety of the following crops soybean, peanut and corn Very good, no residue injury.
