Alfalfa Weevil

I have been getting reports of alfalfa weevil in alfalfa fields. Alfalfa Weevil levels above threshold have begun to be reported throughout the region. Alfalfa growers should monitor their fields closely. Alfalfa weevils are primarily a first cutting pest that can result in reduced yield and quality. Thresholds consider the height of the crop and number of weevils per stem. In some cases it is recommended to harvest early rather than apply insecticide. Spray recommendations also recommend leaving an unsprayed strip to maintain beneficial insects for subsequent cuttings. Complete scouting and threshold information is available in the Mid-Atlantic Pest Management Recommendations for Field Crops.
