A Study On Weeding of 10.8% Hening in Peanut Field

研究了10.8% 禾宁对花生田杂草的防除效果。结果表明:对花生安全,对禾本科杂草和阔叶杂草均有较高的防除效果,能有效提高混合杂草的总防效。在不同的用量中,以50m l/m u 的除草效果最好,对阔叶杂草的防效接近对照药剂,对禾本科杂草的防效也明显高于其它用量。

This paper studied the efficiency of 10.8% Hening in peanut field. It showed that 10.8% Hening did no harm to peanut and can efficiently control boththe grass and broadleaf weed, thus, the total weeding efficiency was increasedobviously. The effect of 50ml per mu is the best among all the dosages. The broadleafed weeding efficiency approach to lactofen and the efficiency for the grass is clearly better than the other dose.
