Strict quarantine measures can help minimize the risk of introducing new pests or diseases into a region.

3.3 Crop Rotation and Diversification

Crop rotation and diversification are practices that can help manage plant pests by disrupting their life cycles and reducing their impact. Rotating different crops in a field can break the pest life cycle, as pests may rely on specific plants for reproduction or survival. Diversifying crops within a region can also help reduce the spread of pests and diseases.

3.4 Resistant Varieties

Plant breeding programs have been successful in developing crop varieties that are resistant to certain pests or diseases. These resistant varieties can help reduce the need for chemical control and minimize crop losses. Resistant varieties are often bred using traditional breeding techniques or genetic engineering methods.

3.5 Sanitation Practices

Sanitation practices, such as cleaning equipment and removing plant debris, can help prevent the buildup of pests and diseases.
