Modern seed genetics help stave off insect problems in crops. Farmers also use Integrated Pest Management techniques which involve inspecting crops and monitoring crops for damage, and using mechanical trapping devices, natural predators (e.g., insects that eat other insects), insect growth regulators, mating disruption substances (pheromones), and if necessary, chemical pesticides. The use of biological pesticides is an important component of IPM. In technical terms, Integrated Pest Management (IPM) is the coordinated use of pest and environmental information with available pest control methods to prevent unacceptable levels of pest damage by the most economical means and with the least possible hazard to people, property, and the environment.

When applying pesticides farmers also have the precision technology to apply directly where needed and are also required to be certified before doing so. Remember, farm products cost the farmer money, so they are used in as small amounts as possible. |
