Integrated Pest Management for Cole Crops and Lettuce

Published 1992 · Publication 3307 · 112 pages

This comprehensive guide provides practical information for carrying out an integrated pest management program in lettuce or any of the cole crops, including broccoli, brussels sprouts, cabbage, or cauliflower. Illustrated with more than 180 high quality photographs, this book provides the grower or consultant with the tools they need to identify, monitor, and make management decisions for more than 100 vertebrate, insect, mite, pathogen, nematode, or weed pests in these crops. Dozens of beneficial insects and other natural enemies are pictured. The focus of the integrated pest management program is to take an ecological approach that provides economical, long-term solutions to pest problems while minimizing hazards to human health and the environment. More than two dozen University of California researchers, researchers, Cooperative Extension specialists, farm advisors, and pest control professionals contributed to this book.
