Technical Abstract: The efficacy of an agent with an iodine-based active ingredient (a. i.) was evaluated for controlling the growth of Fusarium verticillioides, a fungus causing diseases on maize and producing mycotoxins harmful to animals and humans. Iodine is a naturally occurring element that is required for the proper functioning of mammalian metabolism. In spite of iodine being an approved additive for foods used for human consumption, an iodine-based fungicide would be novel. Sensitivity of F. verticillioides conidia to this agent was analyzed for more than 60 isolates. The isolates were categorized into the following groups: 1) different continent, but same mating type and host; 2) different mating type, but same host and location; and 3) different hosts. The continents included North America, South America, Africa, Europe, and China. The mating types included A+, A-, D+, D-, E+, E-, F+, and F-. The hosts included both monocot and dicot plants, corn, peanut, sorghum, cotton, millet, and banana. The results demonstrated that conidial growth was suppressed for all isolates of F. verticillioides. Consequently, the agent with an iodine-based a. i. was universally active against F. verticillioides regardless of the geographic or host origin.
