Why is using resistant varieties significant in IPM?

Using resistant varieties is significant in Integrated Pest Management (IPM) primarily because they are less susceptible to pests. By selecting plant varieties that have developed an inherent resistance to certain pests, farmers can effectively reduce the impact of these pests on crop yields. This natural resistance means that plants can withstand pest pressures better than non-resistant varieties, leading to healthier crops and reduced need for chemical inputs.

The development and use of resistant varieties contribute to sustainable agricultural practices, as they align with the IPM principle of minimizing pesticide usage while managing pest populations effectively. This approach can lead to healthier ecosystems, as fewer chemicals can reduce environmental contamination and preserve beneficial organisms in the soil and surrounding environment. Furthermore, by relying on resistant varieties, growers can save time and resources, allowing them to focus on other pest management strategies that are more sustainable and environmentally friendly.
