The herbicide experimental trails, including 5 herbicides and their fourteen combination treatments, were conducted in spring maize field. Atrazine mixed with each of the 3 herbicides had better phytocidal effect than it was applied alone. The dosages, which were 1650 ml/hm2 of Atrazine38SC with 900 ml/hm2 of Acetochlor90EC,or 900 ml/hm2 of s~metolachlor96EC,or 1950 ml/hm2 of Pendimethalin33EC,were applied to soil surface post-sowing and pre-emerge, the phytocidal efficacies reached to 92%; For the field with dicotyledon weeds, especially Abutilon theophrasti and Acalypha australis Linn, applying 45~60 g/hm2 of Flumetsulam80WG plus either 900~1200 ml/hm2 of s-metolachlor96EC or 900~1050 ml/hm2 of Acetochlor90EC, dicotyledon weeds efficacies were higher than 96%. Additionally, the emerged weeds should be eliminated before these herbicides application.
