Bayer recently made changes in the name, price, and some rates for glufosinate products. The product “Ignite 280SL” has been renamed “Liberty” (it’s deja vu all over again). The formulation has not changed – just the name. The price of Liberty has increased by about 20%, but there are apparently some rebates associated with the purchase of LibertyLink soybeans that make it more economical to use.
While the current label does not reflect this yet, Bayer is also recommending a minimum rate of 29 oz/A for POST applications in LibertyLink soybeans. The rates for burndown use or POST use in corn have not changed.
· In our research with LibertyLink soybeans, the 22 oz rate has often been adequate for POST applications where a broad-spectrum residual herbicide has been applied at planting.
· The higher rate should provide more effective control of giant ragweed and annual grasses, although it is not likely to overcome the weakness of Liberty on barnyardgrass, yellow foxtail, and certain other grasses. These should be controlled with residual grass herbicides applied at planting, or by mixing a POST grass herbicide with Liberty in POST applications.
· Moderate to high populations of giant ragweed will still be most effectively controlled with two POST applications of Liberty, similar to the best strategy when using glyphosate in Roundup Ready soybeans.
We are getting reports of a possible current scarcity in the supply of 2,4-D products, and also a possible concomitant price increase. The reason - Dow is the major supplier of 2,4-D to other formulators/distributors, and the facility that produces it was apparently out of operation for several months. We have no other information on this situation, but are mentioning it here so that growers can research the situation for themselves and take necessary steps to procure 2,4-D or adopt an alternative burndown program (more on these in the next newsletter). Keep in mind that even with a small price increase, the combination of glyphosate and 2,4-D remains the most versatile and economical burndown treatment for many situations.
In 2011, 50 corn silage hybrids representing 12 commercial brands were evaluated in a joint trial with Michigan State University (MSU). One Ohio location is combined with Michigan's two southern (Zone 1) silage locations. The Ohio test site was located in our Northwest Region at Hoytville (Wood County). The two MSU sites are located in Branch and Lenawee counties, which are on the Ohio/Michigan state line. The test results from the three locations are treated as one region.
The plots were planted with 4 row air type planters and maintained by each respective state utilizing standard production practices. The center 2 rows were harvested with MSUs self-propelled forage harvester. Silage tests were harvested uniformly as close to half milk line as possible. Near Infrared Reflectance (NIR) Quality Analysis was performed by MSU using their current procedures. Silage results present the percent dry matter of each hybrid plus green weight and dry weight as tons per acre. Other data presented include percent stand, the percentage of in vitro digestible dry matter, acid detergent fiber, neutral detergent fiber, crude protein and starch. Milk production in pounds per ton and pounds per acre were estimated using MILK2006 (UW-Madison Dairy Science Department).
At Hoytville, silage yields ranged from 7.9-9.9 dry tons in the early test and 8.3-10.8 dry tons in the full season test.
A complete summary of the Ohio results is available online at: http://www.oardc.ohio-state.edu/silagetrials.

February 9, 2012 is this year’s date for the Northern Ohio Crops Day that will be held at Ole Zim’s Wagon Shed, 1375 N. State Route 590, Gibsonburg, Ohio. Featured on this program will be: “Phosphorous and Lake Erie, What has Changed since 1995”, “Pesticide Application, Making Sure You Hit the Target”, “Problem Weeds in Row Crops & Forages”, “Using All the Tools for Growing Corn” and “Precision Agriculture”. These are topics that everyone is talking about and we have some of the top specialists presenting at this meeting.
The program has been approved for Private and Commercial pesticide recertification credits. Participants can obtain all private recertification credits, and commercial credits are 1 hour each in Core, 2A and 2C. We have also received 5 CEU’s for Certified Crop Adviser CEUs. Due to support from our Ag sponsors pesticide recertification credits for private applicators is $25. Commercial credit will be $15 per hour.
The meeting starts at 9:00 a.m. and continues until 3:00 p.m. A $10.00 donation will be accepted at the door to help with expenses that includes a copy of the 2012 Ohio & Indiana Weed Control Guide publication.
Lunch will be provided courtesy of the Northern Ohio Crops Day Exhibitors. The program is a joint effort of Erie Basin EERA Ohio State University Extension. Please call Sandusky County office (419) 334-6340 or e-mail firstname.lastname@example.org with any questions.
The Ohio AgriBusiness Association (OABA) and the Ohio Soybean Association (OSA) have joined forces to offer a one-of-a-kind event series: the Ohio Weed Resistance Workshops. The workshop program will be presented at three events across the state on, February 28, February 29 and March 1, 2012 and is being offered at no cost to registered participants.
The OABA will join with the Ohio Soybean Association and, along with the support of all of our sponsors, put on these workshops. This will be a unique opportunity for both farmers and custom applicators dealing with herbicide resistance to get up to speed on the current state of weed resistance management in Ohio and get insight into future projections, as well as learn about how best to manage it and how to utilize latest technologies.
Presenters will include researchers Dr. Mark Loux and Tony Dobbels of The Ohio State University Department of Horticulture and Crop Science. Representatives from Monsanto and other experts in weed resistance round out the program. In addition to individual speaker presentations, the events will feature a panel discussion with Q&A. CCA credits for the sessions will be available.
All three workshops will begin at 9:00 a.m. and end at 12:30 p.m. and will be followed by a lunch. The dates and locations are as follows:
Northeast Ohio - February 28, 2012
Ohio Agricultural Research & Development Center
1680 Madison Avenue, Wooster, OH 44691
Central & Southern Ohio - February 29, 2012
The Fawcett Center
2400 Olentangy River Rd., Columbus, Ohio 43210
Western & Northwest Ohio - March 1, 2012
601 North Main St., Bluffton, Ohio 45817
