Workgroup Information

Warm Season Vegetables

Summary Focus of the workgroup is on conducting research and education programs in many warm season vegetables with emphasis on fresh market tomatoes, bell peppers, and melons in major production areas of California. Annual workgroup meeting brings advisors, specialists, and AES personnel together to coordinate and exchange information on the high priority issues of sustainable crop production practices, pest management updates, nutrient and water conservation and environmental quality factors, and industry challenges. Additionally the workgroup addresses the needs of the specific commodities on a statewide basis.
