生長激素類除草劑之應用與發展
The Introduction on the Application and Development of Synthetic Auxins Herbicides
摘要
生長激素類除草劑在國外使用於農作物，草坪、牧場、草場治理雜草相當普遍，依HRAC對其化學結構可分類為苯氧羧酸類，如：2,4-D、MCPA、Mecoprop等；苯甲酸類，如：麥草畏；喹啉羧酸類，如：快克草；吡啶羧酸類，如：畢克爛、三氯比、氟氯比、畢克草及氯氨吡啶酸；以及最近研發的芳香基吡啶類，如：氟氣吡啶酯及氯氟吡啶酯，還有歸為其他類別，應用於油菜田的草除靈乙酯。此類除草劑屬多作用點，抗性風險低。本文簡述此類別主要除草劑特性與可防治對象，以及在全球雜草管理應用概況及其發展趨勢，提供需要或欲防除時選擇合適品種開發應用參考，期能有利於雜草管理及生態保護。
並列摘要
Synthetic auxins herbicides are widely used in crops, lawns, pastures and grasslands overseas. According to chemical structures via the HRAC, it can be divided into Phenoxy-carboxylic-acid (2,4-D、MCPA、Mecoprop, etc.); Benzoic acid (Dicamba); Quinoline carboxylic acid (Quclorac); Pyridine carboxylic acid (Picloram、Triclopyr、Fluroxypyr、Clopyralid and Aminopyralid); Arylpicolinates (Halauxifen-methyl and Florpyrauxifen-benzyl); and other catergory such as Benazolin-ethyl used in oilseed rape. This kind of herbicide has low resistance risk in multiple mode of action. In this paper, the main characteristics and weed control of these major herbicides, as well as their application and development trend in global weed management are respectively summarized. This is to provide the reference for selecting suitable herbicides for development and application when need or want to control. It will also be benificial for weed management and ecological protection.
