Tillage: Tillage practices that bury infested corn or small grain residue help reduce the likelihood of disease carryover. The buried residue decomposes faster than when left on the surface, and also the Fusarium spores can’t be released into the air from buried residue. However, plowing is not common in many regions, and minimum or no-till production practices are used.
Under Minimum or No-till Production: Spreading and distribution of chaff and other residue may allow faster decomposition of the residue. Also, chopping or grinding corn residue to reduce the size of the remaining stalk pieces may favor more rapid disintegration of infested residue.
