Technical Abstract: Fusarium moniliforme infections of corn are an agricultural concern because of causing plant diseases and producing mycotoxins harmful to animal and human health. Iodine-based compounds have been used as microbial control agents in human and animal health for centuries, but not in agrochemicals. Control of F. moniliforme growth was analyzed for Plantpro 45 TM [Trade Mark/TradeName] which has an iodine-based active ingredient (a. i.). Isolated F. moniliforme conidia and F. moniliforme-infected seed were assayed for sensitivity to Plantpro. Plantpro was applied to seed by immersion and spraying. Growth of isolated F. moniliforme conidia was inhibited by 5 ppm a. i. Suppression of F. moniliforme growth from infected seed required Plantpro at 250 ppm and 1000 ppm a. i. following immersion and spraying, In summary, laboratory studies indicate Plantpro merits investigation into other commercial techniques of application and field trials for use as a biologically compatible control agent of F. moniliforme growth and ensuing production of the mycotoxins, fumonisins. Plantpro may prove to have commercial applications as a pre-harvest control for seed rot in unfavorable growing seasons and kernel infections via the silk and insect vectors. The agent may also be useful as a post-harvest control to prevent F. moniliforme growth and mycotoxin production when kernels are inadequately stored.
