Implementing cultural practices can prevent or minimize insect migration and establishment in the garden, thus requiring fewer (or possibly no) insecticide applications.
Prevention rather than delay of controls until peak insect activity is the best approach with any combination.Ĭontrol tactics, used singly or in combination, termed as cultural methods include planting under optimal and timely conditions, reducing water stress, timely harvesting, using trap crops, rotating crops, early planting, optimal seedbed preparation, removing crop residues, planting resistant varieties, etc. This multiple strategy approach is called integrated pest management-IPM. Insects are less able to adapt to and overcome this multitiered management style. The best approach is a combination of differing control tactics: (1) cultural controls, (2) mechanical or physical controls, and (3) chemical controls (biorational or conventional). Insects have highly developed senses for locating host plants, so some form of insect control is often necessary to protect vegetable plants from severe feeding damage. Our warm temperatures and long growing seasons are not only ideal for vegetable crops but also for insects-beneficial and pest. Vegetables grown in the southern United States are vulnerable to attack by a variety of insect pests. *This is an excerpt from The Alabama Vegetable Gardener, ANR-0479.
