Focus on Corn is Now Live

Thanks in great part to its
supporters and the work of its editorial committee, led by Carl Bradley, Associate Professor of Crop Sciences at the University of Illinois, and Harold Reetz, Ph.D., Principal of Reetz Agronomics, Focus on Corn has officially launched. The site includes six starter presentations that collectively apply across America’s corn growing regions. The first six topics cover weed management, crop disease, seeding rates, corn silage, residue management, nematodes, and storage management.

Latest Potato Webcast on Powdery Scab

This month’s
Focus on Potato presentation, titled Powdery Scab of Potato by Dr. Robert Davidson, plant pathologist at Colorado State University, will help you identify and manage this devastating and hard-to-control disease using an integrated approach. Key symptoms used to identify the various stages of the disease are described and contrasted with other similar problems.  Management options discussed include avoiding the disease, measuring the inoculum load in soil, making the appropriate cultivar selections based upon the field history, resistance of a given cultivar, inoculum levels and environment; and utilizing specific chemical control.

New Soybean Webcast on Brown Marmorated Stink Bug Includes Early Management Advice

brown marmorated stink bug (BMSB) is causing near catastrophic levels of damage to many horticultural crops.  It is also been documented as a pest of soybean, especially in Maryland, and is spreading south and westward. This Focus on Soybean presentation narrated by Dr. Ames Herbert, an entomologist at Virginia Tech, provides images of BMSB injury to soybean pods, seed, and the ‘stay-green’ condition in fields. Preliminary results of in-field distribution studies and field cage studies that measured impact to soybean are also included along with limited results of insecticide effectiveness studies, and preliminary management recommendations.
