紫茎泽兰新型抑制剂的筛选

Selection of New Herbicides for Control of Eupatorium adenophorum

采用盆栽试验,比较了30种新注册的新型除草剂防除紫茎泽兰的效果。试验结果表明:在白三叶和鸭茅混播的草地中,选用乐吉杀草宝、草不留、灵达,既可取得防除紫茎泽兰的良好效果,又对草地无害;在以白三叶为代表的单播草地,宜使用乐吉杀草宝、草不留、农民乐、灵达、农达;而以鸭茅为主的禾本科的单播草地,可施用盖灌能、威霸、灵达。

For chemical control of Eupatorium adenophorum Sprengel, an experiment was designed to select suitable herbicides and their dosages from 30 new herbicides. The result shows that glyphosate and glyphosate-isopropylammonium were effective in control of E. adenophorum in the mixed sown pasture of white clover and cocksfoot. Glyphosate can be effectively used in the solely sown pasture of White Clover to control E. adenophorum, while triclopyr, fenoxaprop-p-ethyl and glyphosate can be used in cocksfoot pasture. These provide technical support to the control and eradication orE. adenophorum.
