Interpretive Summary:

Technical Abstract: Control of Fusarium moniliforme growth was analyzed using a bio- compatible agent, Plantpro 45 TM [Trade Mark/Trade Name]. The iodine-based active ingredient in Plantpro, has been used as a disinfectant in human and animal health care products, but applications to control plant pathogens is not common. Plantpro was tested for efficacy in controlling F. moniliforme by assaying conidia on agar and F. moniliforme-infected corn kernels incubated both on agar and in perlite. F. moniliforme growth from conidia was inhibited with 5 ppm active ingredient at a concentration of 5.0 x 10/4 (10 to the power of 4) conidia/ml, but growth from infected corn kernels required a much higher concentration. An active ingredient concentration of 250 ppm reduced F. moniliforme growth by 50% from infected kernels under the treatment conditions used. Thus, laboratory studies indicate Plantpro merits investigation into commercial techniques of seed application for use as a bio-compatible control of F. moniliforme growth and ensuing production of the mycotoxin, FB1. Plantpro may prove to have commercial applications to control growth of F. moniliforme during pre-harvest to prevent seed rot in unfavorable growing seasons and during post-harvest when kernels are inadequately stored.
