The following tool was designed to quickly filter the fungicide efficacy table data created by the Crop Protection Network. The information provided was developed by the North Central Regional Committee on Soybean diseases (NCERA-137), The Corn Disease Working Group (CDWG), The North Central Regional Committee on Management of Small Grain Diseases (NCERA-184), and The Alfalfa Pest Management Working Group. For specific information about each crop and how fungicide efficacy was determined visit the page respective to your crop; Soybean Foliar, Corn Foliar, Soybean Seed Treatment, Wheat Foliar and Alfalfa Foliar.
Efficacy ratings abbreviations are as follows: E= Excellent, VG=Very Good, G=Good, F=Fair, P=Poor, U=Unknown, NL= Not Listed

Efficacy ratings were determined by field testing over multiple years and locations. Efficacy depends upon proper application timing, rate, and application method 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, unless otherwise noted. For application timing and use considerations, please contact your local cooperative extension service.
Efficacy ratings abbreviations are as follows: E= Excellent, VG=Very Good, G=Good, F=Fair, P=Poor, U=Unknown, NL= Not Listed
The table is not intended to be a list of all labeled active ingredients. Additional active ingredients may be available but have not been evaluated in a manner allowing a rating. Additional active ingredients may be available in some products for insect and nematode control, however; only some active ingredients for pathogen control are rated.
Many products have specific use restrictions. Restrictions may be present on the amount of active ingredient that can be applied within a period of time or on the number of sequential applications that can occur. Read and follow all use restrictions before applying any fungicide.
The information in these publications is only a guide, and the authors assume no liability for practices implemented based on this information. Reference to active ingredients in these publications is not intended to be an endorsement to the exclusion of others that may be similar. Individuals using these active ingredients assume responsibility for their use in accordance with current directions of the manufacturer.
