We have been receiving several questions about the use of foliar fungicides for wheat. To provide further information regarding relative efficacy of foliar fungicides in wheat, the NCERA 184 (North Central Regional Committee on Management of Small Grain Diseases) recently updated their information of fungicide efficacy for control of certain foliar diseases of wheat. Efficacy ratings were based on field testing of materials over multiple years and locations by members of the committee. Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of application. Differences in efficacy among fungicide products were determined by direct comparisons among products in field tests and are based on a single application of the labeled rate as listed in the table. The Table lists the most widely marketed labeled products and is not intended to be a list of all products. The information in the table is provided only as a guide and does not provide an endorsement for any product.
Any questions about the table can be addressed to Paul: esker@wisc.edu
