[目的]明确苗后茎叶处理除草剂对糜子的安全性及对杂草的防除效果.[方法]糜子苗后4～5叶期采用茎叶施药进行田间药效试验.[结果]50％二氯喹啉酸WP、200 g/L氯氟毗氧乙酸EC、56％2甲4氯钠SP对糜子药害严重.900 g/L 2,4-滴异辛酯EC、38％莠去津SC、48％灭草松AS对糜子相对安全,施药后30 d,对一年生禾本科和阔叶杂草的总株防效为59.5％～91.1％,总鲜质量防效为60.2％ ～ 93.8％.[结论]糜子田苗后防除一年生阔叶杂草可选用900 g/L 2,4-滴异辛酯EC 600 ～ 750 mL/hm2、48％灭草松AS 2250～ 3000 mL/hm2;防除一年生禾本科和阔叶杂草可选用38％莠去津SC 3000～ 3750 mL/hm2.
Effect and Safety of Controlling Weed in Proso Field by Several Herbicide
[Aims] This study aims to confirm the security of herbicides on proso and the control effect on weeds.[Methods] The method ofstem and leaftreatment was carried out at proso seedings after 4-5 leafstage.[Results] Quinclorac 50％ WP,fluroxypyr 200 g/L EC,MCPA-sodium 56％ SP caused serious injury to proso.2,4-D ethylhexyl 900 g/L EC,atrazine 38％ SC and bentazone 48％ AS were relatively safe to proso.On 30 d after spraying,the total strain control effects on annual grass and broadleaf weeds were 59.5-85.1％,the total fresh weight control effect was 60.2-93.8％.[Conclusions] 2,4-D ethylhexyl 900 g/L EC 600-750 mL/ha and bentazone 48％ AS 2250-3000 mL/ha were recommended to be used to proso seedings for controlling annual broadleafweeds.Atrazine 38％ SC 3000-3750 mL/ha was recommended to be used for control of annual gramineae and broadleaf weeds.
