自2008年至2012年，台灣農藥市場趨勢為漸增，2012年農藥銷售金額為74 億(以出廠價計算），較2008年成長18%。2009年全球石油供應及大陸政策等因素， 導致農藥價格大幅増加，2010年即恢復平穩。過去五年除草劑市場略為成長，2012 年除草劑銷售金額達17億新台幣，佔總農藥市場23%，較2008年成長7%。依用 途主要分為非選擇性、水田、旱田用除草劑，市場分配分別為63%，12%及25%。 2012年非選擇性除草劑總銷售金額為10億，較2008年減少5%，主要產品為固殺 草、嘉磷塞異丙胺鹽及巴拉刈，固殺草銷售金額為4.7億，自2009年維持領先地 位，成為銷售金額最高的除草劑，三者單價均有下滑。2012年水田及旱田除草劑 總銷售金額分別為2億及4億，較2008年成長分別為32%及39%。全球新研發成 功之農藥有限，台灣新登記法規厳格，高投資，低報酬的台灣市場，如何引進新 藥劑，以期讓劇毒農藥退場，應是相關當局與廠商的複雑課題。
