Purdue Agricultural Centers – Kiersten Wise


One of the thngs we have been working on since 2009 is trying to understand when fungicides will be best useful in crop production. Now fungicides are relatively new input for most growers. We’ve only really talked about them being in production since about 2007. That’s about the time that crop production became very profitable for growers. Crop prices have increased greatly in the last few years and that allows growers to have more money to put into inputs to protect the crop. With crop prices so high every bushel counts. Growers have no tolerance for yield loss for things that would be from diseases. Our job has been to conduct research at the Purdue Agricultural Centers to understand where fungicides might be beneficial, in what areas and under what predictions systems. One of the questions we’re interested in answering is “What fungicides would be appropriate to control Ear Rots”? What we do is we have research here at the Throckmorton Purdue Agricultural Center and also at the Pinney Purdue Agricultural Center where we are going to wait till this corn gets tall enough to produce an ear. Once those silks come out of that ear we’re actually going to inject the ear with fungal spores and that will cause it to produce a mold over the ear. Then we’ll be able to apply fungicides and understand if the fungicides can halt disease development and if they would be something that would reduce the amount of mold on the ear. From this we’d be able to get recommendations on if the products work and what we should be recommending for Indiana farmers.
