禾耐斯是美国孟山都公司生产的旱地作物选择性芽前除草剂。在福建省福清市花生田每公顷用 6 75～ 90 0ml对花生生长无影响。 12 0 0～ 180 0ml对花生发芽进度及发芽率均无影响 ,但对花生第 2～ 3小叶有轻微药害 ,第 4小叶以后花生生长又恢复正常。药后 30d总杂草株防效达84 %以上 ,鲜重防效达 90 3%以上。各处理花生均有一定的增产 ,增产幅度为 2 3 4%～ 34 0 %。每公顷使用禾耐斯 6 75ml比 50 %丁草胺 3750ml节约 2 1元 ,节约 2 8%。
Wo Naisi is the United States Monsanto dry crop selective crop herbicide. Peanut fields in Fuqing City, Fujian Province, with 6 75 ~ 90 0ml did not affect peanut growth. No effect was observed on the germination rate and germination rate of peanut from 1200 to 180 ml but slight phytotoxicity on the second to third leaflets of peanut and peanut growth returned to normal after the fourth leaflet. After 30 days, the total weed control effect reached more than 84%, and the fresh weight control efficiency reached 90 3%. Peanut processing each have a certain yield, increase rate of 23.4% ~ 34 0%. Each hectare Wo Ness 675ml 50% butachlor 3750ml save 21 yuan, saving 28%.
