Abstract
This Extension Circular reviews what is known about the effects of rotations, tillage practices, and planting and harvest dates on crop insect management, focusing on major crops in Nebraska.
Before the development of synthetic organic insecticides (pre-DDT era), rotations, tillage practices, planting and harvest dates, and other nonchemical cultural controls were commonly recommended for insect management. Research focused on crop rotation and other cultural practices for insect management. With the development of DDT and later insecticides however, research on nonchemical controls decreased markedly.
With the emergence of the concept of sustainable agriculture in the 1980s, there has been increased emphasis on the use of crop rotations, reduced tillage and other cultural practices to promote cropping diversity, provide on-farm sources of soil fertility and animal feed, reduce soil erosion, and reduce pest problems. A greater understanding of how these cultural practices affect insect pest management is needed before they will be widely used.
