Focus on Soybean has launched a new webcast on glyphosate-resistant volunteer corn by Bill Johnson, Extension Weed Scientist at Purdue University. It will be publicly available through May 31, 2011.
Volunteer corn has emerged as one of the most common weeds in Midwest soybean production due to the rapid adoption of glyphosate-resistant corn and sole use of glyphosate in soybean on soybean for weed control. Yield decreases by up to 40% with densities of 16 plants per square meter have been recorded.
In addition, much of the volunteer corn in the eastern corn belt region of the U.S. also carries a Bt trait for insect protection, since the hybrid corn from which it came from was likely to have Bt traits stacked with herbicide resistance traits.
This on-demand webcast presentation, meant for soybean growers, consultants, crop advisers, and other agricultural practitioners, will discuss the competitive effects of volunteer corn in soybean, emergence of western corn rootworm beetles from volunteer corn plants, and control options for soybean producers.
Management considerations will help users minimize volunteer corn's effects on soybean yield, and they will also help users minimize the exposure of insect pests to Bt insect protection traits, slowing the development of Bt resistant insects.

Focus on Soybean is a publication of the Plant Management Network (www.plantmanagementnetwork.org), a nonprofit online publisher whose mission is to enhance the health, management, and production of agricultural and horticultural crops. It achieves this mission through its applied, science-based resources, like Focus on Soybean. PMN is jointly managed by the American Society of Agronomy, American Phytopathological Society, and Crop Science Society of America.
