John Wallace

Growers that plan to integrate cover crops into their rotation will need to determine if their herbicide programs have the potential to reduce cover crop establishment success. The potential for herbicide carryover injury depends on the properties of various herbicides, weather and soil conditions, and the timing of cover crop seeding, says John Wallace, the weed scientist from Penn State University.

During the 2019 National Cover Crop Summit, March 20-21, 2019 — a free-to-attend online event featuring a series of knowledge-building sessions taught by the foremost authorities on covers today — John Wallace will discuss guidelines and principles on the conditions that increase the potential for herbicide carryover, highlight herbicide label considerations, and provide information on herbicide programs that enable fall-seeding cover crops and interseeding cover crops into standing corn, drawing on data from lead Extension weed scientists in various regions. Registration to attend the National Cover Crop Summit can be made at CoverCropSummit.com.

Wallace’s is one of several educational video sessions that will go live each day from March 20-21, allowing National Cover Crop Summit attendees the opportunity to choose the speakers and sessions they’re most interested in and participate on their own schedule. Attendees will also be able to ask questions during the presentation and get timely feedback from the speakers, enhancing the interactive and educational nature of this inaugural event.

The first 10 presenters to headline the National Cover Crop Summit have been announced, along with their session topics. A detailed overview of each presentation can be found CoverCropSummit.com.
