Methods of Pest Control

Methods of pest control:

1.   Chemical and biological methods; some birds, insects or other organisms are deliberately put into the field to kill the pests selectively.

2.   The introduction of disease-resistant varieties of crops for controlling pests and crop diseases.

3.   Crop rotation also removes pests and diseases.

4.   Treatment of seeds, like soaking in fungicide solution, also helps in removing diseases. Pesticides may be of many types such as insecticides, fungicides, rodenticides, weedicides and nematicides. Nematicides kill nematodes, weedicides kill weeds, rodenticides kill rodents, fungicides kill fungi, and insecticides kill insects. Insect-resistant varieties do not allow the pests to grow and damage them.

The chemicals used to kill insects are sprayed either by simple hand-operated machines or by power sprayers.
