Each year, the North Central Regional Committee on Management of Small Grain Diseases (NCERA-184) revises and disseminates a fungicide efficacy table.
Efficacy ratings for each fungicide listed in Table 1 were determined by field testing fungicides over several years and locations by the 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 includes most widely marketed products, and is not intended to be a list of all labeled products.
