Pest management is a key factor in organic agriculture, especially to an economy such as Taiwan, which has limited land and natural resources. Many non-chemical technologies and measures suitable for plant pest management in organic crop production have been developed and improved by researchers and scientists in Taiwan during the past two decades. Presently, the most common non-chemical control methods of diseases and insect pests include: use of healthy seedlings, resistant varieties, and root stocks; resistant induction; natural enemies; sex pheromones; beneficial and antagonistic microorganisms; soil amendment and disinfections; non-chemical pest-killing materials and vegetable oil; cultural practices such as crop rotation, net house cultivation, bagging and mulches; and physical measures such as heat and low temperature treatments. Integrated pest management (IPM), featuring pest identification, monitoring and management including timing application of biopesticides, is recommended to farmers to prevent pest problems. Pest management information in organic agriculture can be accessed through the ARI website.
