There is no best way to deal with pests in agriculture. Pesticides are commonly used, but this may cause many problems. Combining different management operations is the most effective 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 to 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 the balance of nature. To wipe out agicultural pests completely may be very expensie. Sometimes pest damage cost les than the method of control.
Finally, understanding the ecology of the area helps a lot in pest control. Natural enemics 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 effective optio in agriculture.
