As far as is known, none of the commercial corn hybrids are resistant. There are some cultivars of wheat that are resistant to Fusarium. The effects of fertilizer level, plant population, row width and weed populations are still under investigation. The mycotoxin concentration within plants varies with time. In the case of DON, the concentrations decrease, from very high initial values, as the plant approaches physiological maturity, due to the action of plant enzymes.
Mold inhibitors have no effect on mycotoxins already present in stored grain.
Dilution and diversion of infected grain are cost effective. Roasting of grain might lower levels of mycotoxins by oxidizing fines and mold spores which may contain very high levels of mycotoxins. Chemical treatments are effective on a laboratory scale but have a long way to go before becoming cost effective. Attention to those details that tend to lessen the level of mycotoxin contamination will provide benefits to individual farmers for very little additional expense. However, no lasting reduction in the mycotoxin problem will occur until resistant cultivars are developed.
