LONDON, Ohio – The impacts of adjuvants, such as surfactants and crop oil, on corn physiology will be a major focus of discussions during the Certified Crop Advisors College being held at Ohio State University's Farm Science Review on Sept. 24.
The event, intended for Certified Crop Advisors across the Midwest, will take place from 7:30 a.m. until noon. Registration is $75 and includes breakfast, lunch, program materials, an entry ticket to Farm Science Review and a parking pass. Registration deadline is Sep. 11. Registration is limited and there will be no registration the day of the event.
Farm Science Review, Ohio's premiere agricultural event, will take place Sept. 22-24 at the Molly Caren Agricultural Center in London, Ohio.
The CCA program begins on the Farm Science Review exhibit grounds at Beef Street, between Land and Soybean streets. Parking is available in the Exhibitor Parking area at the west end of the grounds. Enter through Gate J and cross Beef Street to the Vice President's Tent. Breakfast is from 7:20 a.m. to 8 a.m. and the program begins at promptly at 8 a.m.
The CCA College, hosted by Ohio State University Extension's Agronomic Crops Team, will feature specialists from OSU Extension, the Ohio Agricultural Research and Development Center (OARDC), and Purdue University Extension.
Peter Thomison, an OSU Extension agronomist, will join Purdue agronomist Bob Nielson for a two-hour presentation on research that points to the connection between corn ear abnormalities and the use of adjuvants. The presentation is titled, "Yield predicaments of growing corn in 2009."
An adjuvant is a product that is added to a spray solution to increase the effectiveness of the active ingredient.
Thomison said that many growers use adjuvants in conjunction with a herbicide, insecticide or fungicide application, making it difficult to determine the cause of any crop abnormalities.
"In Bob Nielsen's research, Bob has been able to tease those treatments apart and differentiate that impact, and what we've found was that adjuvants were causing most of the problem," said Thomison. "The purpose of the discussions during the CCA College will be to educate users on the appropriate application of these materials so as to avoid injury."
Other topics on the agenda include:
• "Winter runoff, a phosphorus challenge," by Robert Mullen, OSU Extension soil fertility specialist. Mullen will summarize some of the Ohio State research on winter nutrient loss.
• "Fungicide use in corn, real or imagined," by Pierce Paul, OSU Extension corn and small grains plant pathology specialist. Paul will discuss diseases issues in Ohio and expectations for economic return.
CCA-CEU credits will be available to those in attendance. OSU Extension and Ag Answers are sponsoring the event, with lunch provided by the OSU Crops and Soils Club.
