There is no best way to deal with pests in agriculture. Pesticides are commonly used, but this may cause many problems. Combinig different management operations is teh most effetive way to control pests.
Firstly, the chemicals in pesticides may build up as residues in the environment. This reduces the quality of farm products. Furthermore, pests can gradually become resistant pesticides. This means that newer and stronger ones have to be developed. Some pesticides affect non target animals such as fish and bees. This disturbs balance of nature. To wipe out agricultural pests completely may be very expensive. Sometimes pest damage costs less than the method of control.
Finally, understanding the ecology of the area helps a lot in pest control. Natural enemies can be used to control a pest. Pesticides that do not affect the natural enemies should be chosen. Therefore, integrated pest management is a safe and more affective option in agriculture
