This present disclosure is related to the field of 1-(substituted-benzoyl)-5-fluoro-4-imino-3-methyl-3,4-dihydropyrimidin-2(1H)-ones and their derivatives and to the use of these compounds as fungicides. 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. The present disclosure relates to 1-(substituted-benzoyl)-5-fluoro-4-imino-3-methyl-3,4-dihydropyrimidin-2(1H)-one compounds and their use as fungicides. The compounds of the present disclosure may offer protection against fungi and fungi like organisms including ascomycetes, basidiomycetes, deuteromycetes, and oomycetes.
