It refers to comprehensive pest control that does not rely solely on chemicals, but instead makes flexible use of cultural control methods that grow crops healthily and remove diseased leaves, and methods of controlling pests using natural enemies, disease viruses, attractants, and repellents. Pest control using pesticides was useful for eliminating pests that are harmful to crops, but it was developed because of the negative aspects that have become apparent, such as killing beneficial insects and causing previously hidden pests and pollution.

化学薬剤だけに依存せず,作物を健全に育てて病葉を取除く耕種的防除法や,天敵,病菌ウイルス,誘引剤,忌避剤を利用して病害虫を防除する方法などを臨機応変に駆使し,総合的に病害虫を防除することをいう。農薬による病害虫防除は作物に有害な病害虫を駆除するのに役立ったが,有用昆虫までも殺したり,これまで隠れていた病害虫や公害を発生させるというマイナス面が顕在化しているところから開発された。
