化学農薬
農薬は農業分野において農作物を病害、虫害、鼠害から保護すると同時に植物の成長を調節し且つ雑草を除去するために用いられる化学薬剤である。農業に適用する以外に、衛生防疫及び林業、畜産業、環境衛生等の分野にも適用することができる。防除対象によって、殺虫剤、殺菌剤、殺ダニ剤、殺線虫剤、殺鼠剤、除草剤、枯葉剤、及び植物生長調節剤等に分けられる。
全世界ではすでに開発された農薬は千種あり,その中の多くは化学によって合成されるものであるが、少ない部分は生物農薬である。
害虫の防除に用いられる農薬は殺虫剤と呼ばされ,早期に用いられた殺虫剤は主に生物農薬(例えば除虫菊、ニコチン等)及び無機化合物であり、本世紀40年代まで、ジクロロジフェニルトリクロロエタンとベンゼンヘキサクロリドの発見と応用のため、有機殺虫剤の発展を大いに促進し,有機塩素、有機リン、カルバミン酸塩という三大類の有機殺虫剤は現れる。殺虫剤は農業に広く用いられる以外に、家庭衛生と他の分野にも用いられる。殺虫剤の使用は害虫を防除する有効な方法であるが、長期にわたって使用される場合に、昆虫が耐薬品性を備えるため、殺虫剤の薬効を低下させ、他の殺虫剤に変換する必要がある。
農作物の病原性微生物の防除に用いられる農薬は殺菌剤と呼ばされ、現在の殺菌剤は主に真菌性疾患を防除する薬剤であり、細菌とウイルスを防除する薬剤の発展速度は遅い。殺鼠剤は鼠類を殺すために用いられ、早期に用いられた急性殺鼠剤について、その欠点は人畜にも毒があることであり、最近数十年間に徐々により安全な慢性殺鼠剤に変更し、慢性殺鼠剤は主に抗凝固薬である。除草剤は接触型除草剤とも呼ばされ、農地の雑草を防除するために用いられる。
植物生長調節剤は植物の生長と発育を調節するという機能を備える農薬であり、非栄養性化学物質であり、少ない使用量だけで植物の生命過程のある環節を促進し又は抑制することができ、それを人間のニーズに合致する方向へ発展させる。
