A new Penn State Extension video series describes practical strategies for monitoring and controlling weeds in fruit and vegetable crops through integrated weed management (IWM). The series of three videos are available in both English and Spanish.
Integrated Weed Management (IWM)
Weeds are a problem in fruit and vegetable crops because they compete with crops for light, water, and nutrients; harbor pests and diseases; and can restrict the movement of workers and equipment in the field. The first video of this series discusses the importance of monitoring, or scouting, and identification of weeds as the foundation of IWM. Strategies to manage weeds include prevention and avoidance, suppression, mechanical control, and chemical control, or the use of herbicides. Successful weed management relies on integrating different strategies, and timing is critical. This video provides examples of integrated weed control programs for various fruit and vegetable cropping systems.
Because weed scouting and identification are so critical for successful weed management, the second and third videos in this series go into detail on how to systematically monitor and identify weeds in vegetable fields and fruit orchards. The videos outline when to scout, what to bring along, sampling patterns, resources for weed identification, and how to keep useful records for specific fruit and vegetable production systems.
