What is one outcome of using resistant crop varieties?

Using resistant crop varieties leads to reduced susceptibility to pests, which is a key principle of Integrated Pest Management (IPM). When crops are bred or selected for resistance to specific pests, they can sustain less damage from those pests compared to susceptible varieties. This not only helps maintain yields but also reduces the need for chemical pest control measures, as the plants themselves are better equipped to fend off pest attacks.

As a result, the cultivation of resistant varieties contributes to the overall sustainability of agricultural practices by lowering the pressure on pest populations, which can be an important factor in managing pest resistance over time. Enhanced resistance means that crops can thrive even in the presence of pests, leading to a healthier ecosystem and reduced environmental impact from pest management strategies.
