- Southeast soybean crop may get extra care this season
- Return would double cost
- Would more than pay for treatment
• Getting maximum value for soybeans will likely be a bigger issue than ever for growers in the Southeast this year.
• Putting higher cost, yield-enhancing inputs into soybeans may be more common, especially if soybeans stay in the $13-$13.50 range at planting time.
FUNGICIDES may be an option for 2012 soybeans.
Would more than pay for treatment
Phipps points out that, as was case with soybeans, even at the lowest levels of wheat yield increases, use of fungicides still would more than pay for itself at current price levels for the crop.
Fungicides used in the 11-year fungicide test of wheat included: Headline, Quilt, Quilt-Excel, Stratego Pro, Prosaro, Priaxor, Headline fb Caramba, Headline fb Twinline and Stratego fb Prosaro.
Headline is a strobilurin that has performed well on both soybeans and wheat throughout the Southeast. It also tends to promotes growth efficiency through better use of nitrogen fertilizer.
According to BASF, the company that markets Headline, the fungicide, “this means healthier plants and higher yield potential.
Quilt combines triazole and strobilurin active ingredients and has been in great demand for use on a number of crops since its introduction into the marketplace in 2007.
Stratego is a popular triazole fungicide that can be used as a stand-alone or in a pre-mix with a number of popular strobilurin fungicides.
Prosaro is a newer fungicide with two different modes of action to protect plants from a broad spectrum of yield-robbing diseases and reduces the likelihood of developing resistance .
Priaxor is a new fungicide scheduled for labeling in 2012, and the new Xemium family of chemistry developed by BASF, the company that markets the product.
Preliminary results from 2011 field trials, showed excellent disease control of a number of diseases, including frogeye leaf spot and septoria brown spot in soybeans.
Caramba is a new triazole fungicide that has provided excellent control of head scab and other common diseases of wheat in tests across the Southeast.
Twinline combines the strobilurin found in Headline with a unique triazole formulation that provides broad spectrum control across multiple wheat diseases, and is especially active on diseases that occur at the flag leaf stage.
These materials range in cost (based on 2011 prices) from $14-$25, with average prices in the $13-$15 per acre range.
The combination of market prices and normal to wetter-than-normal growing season weather could make fungicides a key part of reaching maximum profitability in soybeans and wheat in 2012.
