A mold inhibitor integrated within a matrix and a method of making the same are disclosed. The matrix is preferably made of a processed sorghum grain, and preferably from hybrids of Milo. The grain is subjected to decortication and extrusion. Agents are added to the decorticated Milo prior to extrusion. The agents may be anti-fungal agents or anti-microbial agents. In use, the produced matrix is spread and placed upon a targeted area which requires either remediation or prevention of growth of fungus or microbes.
