(接上期)三、百草枯(paraquat)百草枯属于双吡啶类非选择性触杀性除草剂,也是与草甘膦竞争非选择性除草剂市场的主要对手。百草枯2005年销售额为3.7亿美元,2007年销售额为5.1亿美元。主要应用于果园、蔬菜、苗圃和非作物除杂草。百草枯在1972年开始遇到草甘膦的挑战,虽然草甘膦具有内吸传导活性的优点,但是百草枯始终占据价格优势,而且最初在防治一年生杂草中一直占上风,这两种除草剂相互竞争10多年。直到1986年草铵膦进入市场,开始形成非选择性除草剂群雄并存的局面。
(Continued) Third, paraquat Paraquat is a non-selective double dipyridyl contact herbicide, glyphosate is also competitive with non-selective herbicides market, the main rival. Paraquat 2005 sales of 370 million US dollars in 2007 sales of 510 million US dollars. Mainly used in orchards, vegetables, nurseries and non-crop weeds. Paraquat began to meet the challenge of glyphosate in 1972. Although glyphosate has the advantage of internal absorption conduction activity, paraquat has always held the price advantage and initially prevailed in the control of annual weeds, both of which Agents compete with each other for more than 10 years. Until 1986 ammonium glufosinate into the market, began to form a non-selective herbicide co-exist.
