BASF presented technical information and aerial applicator experiences for TwinLine™ and Caramba™ fungicides at the National Agricultural Aviation Association’s (NAAA) annual conference today. Both fungicides received EPA registrations for cereals this year.
“TwinLine and Caramba strengthen the BASF wheat fungicide portfolio by providing broad-spectrum activity on rust, head scab and other major cereal diseases,” said Amber Shirley, Ph.D., senior technical service specialist with BASF.
TwinLine, labeled for barley, oats, rye, triticale and wheat, combines pyraclostrobin, the active ingredient in Headline® fungicide, and metconazole.
“TwinLine, specifically designed for aggressive wheat diseases like stripe rust, delivers multiple benefits, including broad spectrum disease control and Plant Health benefits, including drought tolerance and stronger stands for easier harvest and higher yield potential,” Dr. Shirley said. “The flag leaf is the most important contributor to yield. With a wide application window and an aerial label of two gallons per acre and greater, TwinLine is perfectly suited for an on-demand market at the flag leaf timing.”.
During the technical presentation, Dr. Shirley shared a summary of 27 BASF and university small-plot, replicated trials that were conducted in 2008. The tests were conducted with TwinLine and two competitive products – Quilt® fungicide and Stratego® fungicide – and included untreated plots. TwinLine consistently delivered higher yield results compared to both competitor products and increased yield by 10 bu/acre when compared to the untreated plots.
Summary of Yield Results
• TwinLine – 81 bu/acre
• Quilt – 79 bu/acre
• Stratego – 78 bu/acre
• Untreated – 71 bu/acre
Caramba™ fungicide, formulated with only metconazole, is another highly-effective fungicide technology in the BASF wheat fungicide portfolio and delivers premium performance on head scab. Caramba is labeled for use on barley, oats, rye, sugarbeets, triticale and wheat.
“Caramba provides excellent activity on head scab, which is one of the most destructive wheat diseases and can result in reduced yield and quality if left untreated,” Dr.Shirley said. “Suppression of head scab by Caramba results in significant yield protection and reductions of deoxynivalenol (DON) levels in grain.”
In 2008 field use, aerial applicators reported that they found TwinLine and Caramba very easy to use when they were applied on grower farms. TwinLine was a part of a large scale, on-farm demonstration program, while Caramba was applied commercially for head scab in wheat.
Both TwinLine and Caramba are EC formulations labeled for aerial applications at two gallons per acre or more on cereals.
