3 Tips for More Economical Fungicide Applications

When weighing purchase decisions, you consider many factors, but ultimately you want to maximize your return on investment potential. However, variables that are out of your control sometimes make that hard to do.


Here are three steps you can take to help make more economical fungicide application decisions, regardless of what the season brings.


1. Identify responsive hybrids and prioritize spray applications.

If you typically apply fungicides to all of your acres but can’t make that work this season, you may have some tough decisions to make. One thing you can do is prioritize your fungicide applications based on hybrid response to fungicide (RTF) scores. Based on WinField United Answer Plot® research, there could be up to a double-digit yield return on fungicide applications when a hybrid has a high RTF score, even with low disease pressure. That’s because certain fungicides help maintain plant health so crops are able to photosynthesize later into the season. The extra energy is used to produce more high-quality grain.


2. Apply the right products.

When choosing fungicides, active ingredients matter. I recommend a fungicide that provides multiple modes of action against the diseases you’re most likely to see. These products can offer the best disease control and also help mitigate the spread of fungicide resistance.


Regardless of the fungicide you choose, you can maximize its efficacy by adding an adjuvant. MasterLock® adjuvant can reduce drift potential and help get more fungicide active ingredient deeper into the canopy where many diseases begin. It’s formulated without nonylphenol ethoxylate (NPE), which reduces the risk of arrested ear development when applied near tasseling time in corn. MasterLock also contains a surfactant that helps the active ingredient stick to the leaf’s surface for better absorption. Our replicated trials show a 5.7-bushel-per-acre average yield increase in corn when MasterLock is added to the spray tank along with a fungicide, compared to using a fungicide alone.1


3. Pair fungicides with other applications.

To help mitigate application expenses, try to identify ways to pair your fungicide application with other trips you’re already making through the field. For example, you may be able to add fungicides with plant nutrition applications to boost plant health with one trip through the field. WinField United MAX-IN® foliar nutrient options can help drive nutrients into the plant with its patented CornSorb® technology.


It pays to adopt a thoughtful strategy for your fungicide applications. Maintaining plant health will be critical to achieving optimal return on investment at the end of the season. Speak with your local WinField United retailer to learn more about disease control options that fit your budget.

Important: Before use, always read and follow label instructions. Crop performance is dependent on several factors beyond the control of WinField United, including without limitation soil type, pest pressures, agronomic practices and weather conditions. Growers are encouraged to consider data from multiple locations over multiple years and be mindful of how such agronomic conditions could impact results.
