近年来随着水稻直播面积不断扩大,杂草的发生日趋严重。为探讨53%苄嘧·苯噻酰WP在水稻直播田的应用效果,于1999~2000年在湖南、上海等地进行了试验。试验结果表明,53%苄嘧·苯噻酰WP具有安全、广谱、增产的特点。1材料与方法1.1供试除草剂供试除草剂有53%苄嘧·苯噻酰WP、50%?
In recent years, with the direct broadcast area of rice continues to expand, the occurrence of weeds increasingly serious. In order to investigate the application effect of 53% benzethonium thiophenyl WP in direct seeding rice, experiments were carried out in Hunan, Shanghai and other places from 1999 to 2000. The test results showed that 53% benzylthiophenyl thioacyl WP has the characteristics of safety, broad spectrum and yield increase. 1 Materials and methods 1.1 The test herbicides tested herbicides 53% benzylthiophenyl thioacyl WP, 50%?
