Integrated Pest Management
There is no best way to deal with pests in agriculture. Pesticides which are commonly used may cause many problems. I think combining different management operations is the most effective way to control pests.
Firstly, the chemicals in the pesticides may build up as residues in the environment and in the soil which absorbs the chemicals. This reduces the quality of farm product.
Secondly, pests can gradually become resistant to pesticides. This means that newer and stronger ones have to be developed.
Lastly, some pesticides affect non target plants and animals such as fish and bees. This affects the ecology and environment as well.
So, understanding of ecology of an area helps a lot in pest control. Pesticides should be chosen and applied carefully so that they don't affect the ecological balance and environment.
Therefore, integrated pest management is a safe and more effective option to fight pest in agriculture and livestock.
