Objectifs
This project has three objectives : Reestablish the economic threshold for blue alfalfa aphid to reduce the number of applications and amount of insecticides used to manage this pest and increase profitability, Investigate the efficacy of selective vs. broad-spectrum insecticides for the management of BAA and other alfalfa aphids to reduce health and environmental impacts of broad-spectrum insecticides currently used to manage these pests, and Provide IPM training on alfalfa integrated pest management and collect baseline data from PCAs in the southwest desert on current pest management practices for aphids in alfalfa, including economic thresholds used, insecticide use, and general knowledge these key pests and IPM principles. The goals of the third objective are as follow : As part of the PIs' Extension and outreach programs, several Extension meetings will be conducted to teach alfalfa pest IPM in AZ, CA and UT, including sharing of any research results that will be available during this project term. During these meetings we will conduct audience response surveys to collect baseline data on the use and adoption of economic thresholds, selective vs. broad-spectrum insecticides, and general principles of IPM. Conduct two field days at thee research sites of the three states to showcase research results, educate PCAs and growers about the outcome of the studies and their implications for aphid management programs in alfalfa. Baseline data will be collected at these field days as described in the project evaluation section. Large demonstration trials are under planning at the Maricopa Agricultural Center, AZ. About 30 acres of alfalfa will be established during the fall of 2016 where the results of the first and second objects will be demonstrated to growers and PCAs on large scale. Growers and PCAs from across the alfalfa hay production areas of southwestern desert will be invited to these demonstration trials.
