为明确30％氰草·莠去津悬乳剂与30％磺草·莠去津悬浮剂对玉米田杂草的防除效果以及在玉米不同叶龄期使用的安全性,开展了2个除草剂品种在玉米不同叶龄处理与90％莠去津水分散粒剂播后芽前土壤处理对田间杂草防效和产量影响的田间对比评价试验.结果表明,1575ga.i./hm230％磺草·莠去津悬浮剂在玉米3～4叶期和6～7叶期施用·1350ga.i./hm230％氰草·莠去津悬乳剂在玉米3～4叶期施用对玉米安全,杂草防效好,玉米产量比清水对照增加10％以上,杂草防效和玉米产量均优于2160ga.i./hm290％莠去津水分散粒剂播后芽前土壤处理;1350ga.i./hm230％氰草·莠去津悬乳剂在玉米6～7叶期施用对玉米有药害,其杂草防效和玉米产量均不及2160ga.i./hm290％莠去津水分散粒剂播后芽前土壤处理.
