This present disclosure is related to the field of to N-(substituted)-5-fluoro-4-imino-3-methyl-2-oxo-3,4-dihydropyrimidine-1(2H)-carboxamide compounds and their derivatives and to the use of these compounds as fungicides. This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/746,837 filed Dec. 28, 2012, which is expressly incorporated by reference herein. Background and Summary of the Invention Fungicides are compounds, of natural or synthetic origin, which act to protect and/or cure plants against damage caused by agriculturally relevant fungi. Generally, no single fungicide is useful in all situations. Consequently, research is ongoing to produce fungicides that may have better performance, are easier to use, and cost less.
