Thinking of Fungicide in your corn?
I read an article from No-Till Farmer today about using corn fungicides. This has been a source of some controversy for several years. This article quote Kierston Wise of Purdue University on Midwestern research on fungicides. She says to only use fungicide if you have disease, but many of the fungicides are not effective once there is a disease outbreak. She says that just having the conditions is no guarantee of an outbreak. So how do you decide if you need fungicide? Toss a coin? I would go with cool moist weather and susceptible hybrids, but that could leave you spending $30 per acre without needing to. I hope researchers come up with some more concrete advice.
