New Fungicide Decision Tool For Farmers

New Fungicide Decision Tool For Farmers

Iowa On-Farm Network has online management tool to help growers determine if it will be profitable to apply a foliar fungicide on soybeans. Each grower uses their own fungicide cost and bean price information.

The Iowa Soybean Association On-Farm Network has released a fungicide management calculator tool it has developed to help Iowa growers determine the probability of seeing a profitable return from using fungicides on soybeans.

The calculator allows growers to put in their own soybean prices (either projected or a price they've already booked for their crop) and actual product and application costs to see whether fungicide use is likely to pay off. The data used to create the calculator came from five years of comparisons made through 282 replicated strip trials across the state using Headline fungicide.

Helps growers determine probability of profitable fungicide use

After inputting market price and cost, the calculator returns a graph showing soybean yield response to the fungicide, the break-even yield increase the grower would need to justify fungicide use, the probability of actually seeing a profit, projected profit/loss from using the fungicide, and, finally, the number of years out of five that fungicide use could be expected to be profitable.

The calculator is available for anyone to use at To learn more about the On-Farm Network and to view the results of other studies conducted on farmer's farms across Iowa, go to The On-Farm Network is a program of the Iowa Soybean Association. It works with growers doing research on their own farms to improve yields and profits while minimizing their one environmental footprint. The network is directed by an 11 member advisory council made up of involved, concerned growers.
