Beauv, Commelina communis L.,Chenopodium serotinum,Acalypha australis L., with control effectiveness of more than 90 percent.Dosage at 3000ml/nec is suitable for application to weed density of more than 200 per square metre,3750-4500ml for weed density of less than 200 per square metre.Effictive control of weed during all the corn growing stage can be realized through only once spring of the weed killer with treatment on soil surface in 5~9 days after sowing,with amount of water at 450 Kg per hec.It has proved that the weed killer has no harmful effect on maize and next crop. |
