除草剂与杀虫、杀菌剂不同,它是在高等植物中通过时差、位差、植物形态差异等表现出选择性。花卉苗圃种植的苗木种类繁多,栽培方式亦多样,有许多除草剂不宜在花卉苗圃应用。现作简单介绍。1.防除阔叶杂草的苗后除草剂:包括2甲4氯、2,4-滴、苯达松、百草敌、使它隆、虎威、克莠灵、好事达等。其中2甲4氯、2,4-滴由于环境污染的原因,已在欧洲许多国家被禁用。2,4-滴的飘移污染,已造成大面积蔬菜、棉花、高尔夫球场的树木严重药害。2,4-滴的另一问题是容器污染,凡盛过2,4-滴的喷雾器,即使 Herbicides and insecticides, fungicides different, it is in the higher plants through the time difference, potential difference, differences in plant morphology showed selectivity. Flower nurseries planted a wide variety of seedlings, cultivation methods are diverse, there are many herbicides should not be applied in flower nurseries. Now for a brief introduction. 1. Broad-leaved weed control post-emergence herbicides: including 2 A 4 chlorine, 2,4-drip, bentazon, paraquat enemies, to make it long, tiger Granville, grams of aniline, good things and so on. Among them, 2 A, 4 C and 2,4-D have been banned in many European countries due to environmental pollution. Drift pollution of 2,4-drip has caused serious damage to trees in large areas of vegetables, cotton, golf courses. Another problem with 2,4-D drops is container contamination, where a 2,4-D drop of nebulizer, even though
