在湿播稻田,试图采用手工除草或机械除草都是不现实的,用除草剂也许是最佳的选择。可是大部分除草剂施药时限狭窄,要求严格,为保证作物安全和达到较好的除草效果只能采用喷雾施药或撒布颗粒剂。对作物较安全的除草剂,例如,苄嘧黄隆(bensulfuron)和丙草胺(pretilachlor)+fenclorim混剂的出现,使灵活施用除草剂具有实际可能性。Peudpaichit等(1985)曾经报导,泰国用苄嘧黄隆作种子处理、喷雾施药、制成颗粒剂撒布或在漫灌田集中点施放。在
In wet-sowing paddy fields, it is not realistic to attempt to use manual weeding or mechanical weeding. Using herbicides may be the best choice. However, most of the herbicide application time limits are strict and strict. To ensure crop safety and achieve better herbicidal effect, only spraying or spreading granules can be used. The emergence of herbicide safer crops, for example, bensulfuron and pretilachlor + fenclorim compounds, gives the practical possibility of flexible application of herbicides. Peudpaichit et al. (1985) reported that Thailand used bensulfuron-methyl for seed treatment, spray application, granulation and sprinkling or concentrated application at floodplain. in
