Abstract
It was difficult to select effective herbicides in preemergence and postemergence periods in sorghum.Because of the situation of lacking of effective method to control the weeds,the herbicides screening test was carried out in Guanjia techno park and Langjiazhai of Suihua Branch of Heilongjiang Academy of Agricultural Sciences in 2010 to give farmers some suggestions on herbicides selection.The results showed that the control efficiency on weeds was up to 89.50% through the closed soil treatment with metolachlor and pendimethalin in preemergence period,and there was no obvious adverse effect on the emergence and growth of sorghum.Metolachlor and atrazine used in preemergence period and atrazine used in postemergence period had high inhibition on weeds.The control efficiency of quinclorac and 7.5% MCPA and 30% bentazone used in postemergence period in stem treatment on weeds was up to 86.40% and 81.37%,respectively,and there was no obvious adverse effect on sorghum growth.
