2012 Weed Control Guides

It is that time of year when we need information about weed control chemicals, tank mixes, etc. Mark Van Gessel the University of Delaware Extension Weed Specialist, who also serves as our Field Crop Weed Specialist in NJ has posted the 2012 Weed Control Guides on the University of Delaware Weed Science Page. On the site you will find the control recommendations for corn, soybeans and forages. There is also a link to the Mid-Atlantic Field Crop Recommendations. These useful resources can all be found in one place.

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.
