Expect Results from Early Fungicide Applications

Lindsay Bergmark, Mid-West Fertilizer, INC.
There’s no doubt that when commodity prices are low, non-traditional applications, like an early season fungicide application, may be hard to justify. But in a climate where producing more bushels is important as ever, V4-V7 fungicide applications are becoming more popular.

Early Season Benefits

Early corn fungicide applications often occur between V4 and V7 growth stages. Typically, these are thrown in the tank with a post emerge herbicide application, lessening application costs and alleviating an extra pass across the field. We have seen the best results when spraying at V6 or V7. Many trials have been showing a 5 bushel advantage when spraying at this timing, even in dry conditions.
“This early timing is when the corn plant is determining the maximum size of the ear in terms of length and size around,” says Rob Pitman, agronomist at Mid-West Fertilizer. “Protecting the corn from stress and potential disease at this stage can provide yield and plant performance benefits. Increased stalk strength, and delayed disease progression can result.”

How Will My Hybrid React?

Response-to-fungicide (RTF) scores are key indicators of your potential economic benefit, allowing you
to weigh possible yield gain against application costs. 2016 Answer Plot® data shows a strong fungicide yield response in both corn and soybeans. Across all locations, an 88 percent positive response rate was observed in corn and a 92 percent positive response rate was observed in soybeans.

Using data found within the R7 Tool® by Winfield United® you can better understand your own hybrid’s potential.
