After walking more than 40 corn fields and sampling more than 3,500 ears, we believe that Gibberella ear rot (GER), and consequently, vomitoxin levels likely will be much lower this year than they were last fall. This is because conditions during the weeks after silking were considerably less favorable for the disease to develop and the toxin to contaminate grain this year than last year. However, as is often the case, there were a few exceptions.
Many growers know the benefits of fall herbicide treatments, and like how fields look the following spring. We know that it’s not always possible to complete harvest and then still find the time, weather, or field conditions to get herbicides applied. This is just a reminder that we have a lot of time yet to apply herbicide this fall. In OSU weed science plots, we have typically applied most of our fall herbicides in early to mid November, but have occasionally applied into December and maintained effectiveness on winter annuals and dandelion. When we get a period of very co
One of the main reasons soybean cyst nematode (SCN) remains the most economically important pathogen of soybean is that it can cause yield loss between 15 and 30% with absolutely no visible symptoms. Resistance to SCN remains the most effective management strategy when rotating to a non-host crop is not an option. The predominant source of resistance in most commercially available soybean cultivars comes from Plant Introduction (PI) 88788, which confers resistance to SCN Type 0 (formerly race 3).
Soybean cyst nematode (SCN) is a major soybean pathogen that continues to spread throughout Ohio. Yield reduction commonly occurs with no visible above-ground symptoms. To know if this nematode is present in a field, soil samples must be properly collected and handled. The presence of SCN in a field, but more importantly, the SCN numbers will determine the best management strategy.
The fall is a great time to collect soil samples to identify any needs for lime, P, and K. Soil sampling either this fall or spring 2022 will be particularly important with the high costs of agricultural inputs.
The Certified Crop Adviser (CCA) Exam Training program, delivered by OSU Agronomic Crops Team members, will be available online and in-person to help you prepare for the 2022 CCA exams. An in-person two-day training class will be held on January 12 & 13 from 9 AM to 5 PM each day at the Shelby County Ag Building, 810-820 Fair Rd, Sidney, Ohio 45365.
