Result In peanut seedling stage, spraying 900 ml/hm^2 quizalofop-P-ethyl EC on the grass weeds such as Barnyard grass, Green bristlegrass and Goosegrass had 100% control effect, but it had a poor control effect on some broad-leaved weeds. While, spraying 600 and 720 ml/hm^2 quizalofop-p-ethyllactuofen EC had remarkable effects not only on the grass weeds such as B. grass but also on the broad-leaved weeds such as Purslane, Cirsium setosum and Dayflower, with the control effect of more than 80%. Both of the 2 herbicides would not produce some slight contact drug spots on the part of peanut leaves and the drug spots on the leaves could be recovered in 1 to 2 weeks, which couldn't affect the growth and yield of the peanut in middle and late stage. So the 2 herbicides had good selectivity.

结果］在花生苗期喷施900 ml/hm^2精喹禾灵乳油对稗草、狗尾草、牛筋草等禾本科杂草具有100%的防效，但对一些阔叶杂草防效较差，而喷施600和720 ml/hm^2精喹乳氟禾乳油则除了对稗草等禾本科杂草有特效外，还对马齿苋、刺儿菜、鸭跖草等阔叶杂草具有显著的防效，均达80%以上。2种除草剂均对花生叶片局部产生一些轻度的接触性药斑，药斑在12周内可恢复，不影响花生的中后期生长及产量，具有很强的选择性。
