Integrated Pest Management: Chemical Use
In Integrated Pest Management (IPM), chemicals should not be the first course of action. IPM is an approach that emphasizes the use of multiple strategies to manage pests, including cultural, biological, and physical methods. Chemicals should only be used if non-chemical methods have been unsuccessful or ineffective.
Chemicals should be used as a last resort, when the pest population is beyond a manageable level or when there is an immediate threat to the crop. This decision should be made based on careful consideration of the potential risks and benefits of chemical use.
For example, if a farmer observes a pest on their crop, they should first try methods such as crop rotation, use of resistant crop varieties, or biological controls like introducing natural predators or parasitoids. If these methods are not sufficient to control the pest, then chemicals may be considered.
