You have several corn fields and only one of you — how do you prioritize which field gets fungicide first?
2015 is shaping up to likely be a high disease pressure year, says Albert Tenuta, field crop plant pathologist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), and a little planning now could make the fungicide season a little smoother for many.
In this Corn School video, Tenuta first recaps proper fungicide timing, when you’re most likely to realize a return on that investment of product, time and fuel. From there we move on to what foliar diseases you’re looking for early on
When deciding on which fields to scout more often and then likely spray first (if at all), Tenuta says remember that not all corn hybrids are created equal when it comes to genetic resistance (click here for that full discussion), so knowing which fields are more likely to show disease is key. Those fields that were in corn last year are also going to be a higher risk, as will fields with more corn residue.
Just what are you looking for? You’re looking for northern corn leaf blight, rust, eye spot and more. Follow this link to see more on corn pests.
