| Abstract：The indoor herbicidal activity of a new herbicide pyroxasulfone with soil spray blocking treatment against four main weeds in soybean fields, Abutilon theophrasti, Chenopodium album, Setaria viridis and Digitaria sanguinalis, was studied by using the indoor bioassay method, and evaluated the safety of pyroxasulfone against three soybean varieties. The results showed that pyroxasulfone had high biological activities on four kinds of weeds and had good safety for the three soybean varieties, the selectivity index was higher than 2. So it can be used as a soil sealing treatment agent in soybean field. |
