With our warm temperatures and high humidity, Southeast Iowa is an ideal environment for diseases like gray leaf spot, northern corn leaf blight, and common rust. Not to mention the new fungal threats that seem to pop up, like tar spot (see article here). To shield your crop from the high fungal pressure of our region, fungicide application should be considered in your protection plan every growing season.
Below are response scores that shows the effect fungicide application is likely to have on each hybrid. But how does this data play into your fungicide plan? If the response score is high or moderate, fungicide application is a no-brainer. However, even with low response scores, fungicide applications on those hybrids shouldn’t be completely thrown out the window. In addition to disease protection, fungicide can also increase yield. The past 6 years of ProVantage data has shown an average 16.5 bu/acre yield bump on corn acres. Research from Winfield United has also shown an average 17.5 bu/ac yield increase across low, medium, and high RTF (response to fungicide) scores.
By considering the fungicide response scores of your hybrids, you can make the most informed decision for fungicide application.
If you need some guidance on evaluating the effectiveness on particular hybrids or how it pencils out, give your Stutsman agronomist a call to help navigate your 2020 crop protection plan.
