2017 Answer Plot® Insight #2: Expect Results From Fungicides

  • Jul 06, 2017
This is the second in a series of four posts highlighting key insights from 2016 Answer Plot® field data and trials.

Using data from our Answer Plot® Program, WinField United strives to help farmers make the right decisions throughout the growing season. One area we have focused on recently is response-to-fungicide (RTF) scores and the potential economic benefits of making a late-season fungicide application.

Granted, with current low commodity prices, the expense of a late-season fungicide application can be difficult to justify. And the questions, “Is it worth the cost to spray fungicide?” and “Will I get my money’s worth out of this expenditure?” are legitimate. What is certain is that making the right decision about fungicide applications requires a calculated approach.

RTF scores are key indicators of the potential economic benefit of applying fungicides and allow you to weigh possible yield gain against application costs. Answer Plot® data from 2016 shows a strong fungicide yield response in both corn and soybeans. Across all locations, an 88 percent positive response rate was observed in corn (a 15.3-bushel-per acre yield advantage) and a 92 percent positive response rate was observed in soybeans (a 2.1-bushel-per-acre yield advantage).

We also test each hybrid for its individual response. Some hybrids respond exceptionally well to a fungicide application and are “must spray” hybrids. Others do not respond as well, so applying a fungicide may not pay for itself. We can help you think through the possibilities to ensure you are putting your dollars in the right place and optimizing your investment.

Contact your local retailer for hybrid-specific response scores and for further information on a late-season fungicide application.

At 67 Answer Plot® locations in 12 states, the average corn fungicide response was a 15.3-bushel-per-acre yield advantage.



At 38 Answer Plot® locations in 11 states, the average soybean fungicide response was a 2.1-bushel-per-acre yield advantage.
