How Do I Address Foliar Diseases In Corn?
Oct 05, 2010
Question: I’ve had some problems with foliar diseases in my corn this year. Any suggestions for next spring?
Answer: Are you aware of why you’ve had the problem? If you’ve had difficulty doing normal tillage and burying residue the past couple of years, you may have inoculum built-up. Inoculum can also come in from neighboring fields. Corn-on-corn in no-till and strip-till supports the toughest disease situations of all, especially if you grew a susceptible hybrid that produced a lot of inoculum. In any case, hybrid selection becomes very important. Resistance to diplodia is fairly easy to find; talk to your seeds person so he or she can also recommend hybrids with good scores on fusarium and gibberella.
