Summary:
Management of aphid outbreaks has been a component of alfalfa growers programs for some time. In particular, management of alfalfa weevils with insecticides has often led to secondary outbreaks of aphids, in part because these broad-spectrum insecticides eliminate predators that keep aphids in check. More recently aphids have occurred in high abundances, resulting in economic damage to alfalfa crops. Novel insecticide classes have been registered for alfalfa against aphids recently that may improve their management. More information in the region is being gathered by the PIs to validate current aphid thresholds and IPM strategies through a USDA-NIFA-Alfalfa and Forage Research Program. We propose initiating an outreach and implementation IPM program to disseminate research-based information to improve IPM practices for key alfalfa pests, and promote and evaluate adoption and impact of new practices through a coordinated Extension programs.
The outreach efforts will emphasis selective insecticides use to help preserve natural enemies in alfalfa, which will provide surrounding crops in the agricultural landscape with improved biological control, potentially leading to areawide reductions in pesticide use. The evaluation objective aims at collecting baseline data from Pest Control Advisors and growers in the southwest on current pest management practices for major insect pests in alfalfa. The collected data will help measure program impacts, change in clientele adoption of IPM practices and measured outcome to help with future grants. Objectives: 1- Provide IPM training on alfalfa integrated pest management in Arizona, California and Utah based on current research and available IPM guides 2- Collect baseline data from PCAs in the southwest desert on current pest management practices for major insect pests in alfalfa, including economic thresholds used, insecticide use, and general knowledge these key pests and IPM principles. |
