Is a fungicide pass on corn or soybeans worth it? 

 

IS A FUNGICIDE PASS WORTH IT?

Fungicides primarily prevent or mitigate disease pressure, but they can also increase water use efficiency, photosynthesis, nitrate reductase activity, increase the window for grain fill, and improve stress tolerance. How a fungicide works depends on its mode or modes of action.

 

 

WHEN SHOULD YOU SPRAY?

Later applications in corn control diseases that tend to move in after pollination. Many fungicides provide plant health benefits that keep the plant healthier during grain fill.

 

3-YEAR MULTI-LOCATION FUNGICIDE TIMING ROI

 

 

7-YEAR MULTI-LOCATION FUNGICIDE AND INSECTICIDE TIMING ROI

 

 

OBSERVATION

Approximately 70% of a soybean plant's yield comes from nodes 6 to 13. Those nodes are usually present at the R3 growth stage. 

 

FUNGICIDE: PRODUCTS

 

PRODUCT DESCRIPTIONS

 

TRIVAPRO®

Trivapro delivers long-lasting disease control and crop enhancement benefits with three complementary modes of action (strobilurin, triazole, and SDHI). Trivapro has exceptional rainfastness and provides longer residual control, extending plant health.

Key Benefits: Especially strong on common and southern rust 

 

DELARO™ 325 SC

Delaro contains two broad-spectrum modes of action in one product. It also contains 2.8 times the rate of Proline® compared to Stratego YLD® and provides both preventative and curative defenses against disease.

Key Benefits: Delaro is transported systemically throughout plant tissue and moves both on the inside and outside of the plant 

 

HEADLINE AMP®

Headline AMP fungicide provides two modes of disease control. The first provides preventive activity and the second is a triazole that provides postinfection disease control. One of the active ingredients in Headline AMP is F500®, which helps plants grow more efficiently and allows them to focus their energy on producing higher yields.

Key Benefits: Provides consistent plant health benefits in all environments 

 

PRIAXOR®

Priaxor fungicide protects plants from a broad spectrum of fungi. It is powered by Xemium® fungicide, an active ingredient that continuously distributes its chemistry throughout the leaf. Priaxor is a combination of Xemium fungicide and F500® - the same active ingredients in Headline AMP®.

Key Benefits: Decreased plant stress and increased photosynthesis and plant health 

 

STRATEGO® YLD

Stratego YLD fungicide combines triazole technology with strobilurin chemistry for disease control in soybeans. It provides both preventative and curative activity and more systemic movement.

Key Benefits: Lower use rate allows for easier handling, storage, and mixing 

 

FUNGICIDE: YIELD ADVANTAGE

 

CORN MULTI-YEAR YIELD ADVANTAGE

 

 

OBSERVATION

The wide alleys at our PFR sites create an increased win movement. Because of the winds and frequent use of fungicides, we often see lower responses to those applications that you might see on your farm.

 

SOYBEAN MULTI-YEAR YIELD ADVANTAGE

 

 

FUNGICIDE: PRACTICES

 

TIME OF DAY

Fungicide applications appear to be more effective when applied in the morning. A dew may help spread the fungicide over the surface of the leaf.

 

2-YEAR MULTI-LOCATION 8 A.M. FUNGICIDE APPLICATION ROI VS. 3 P.M.

 

 

OBSERVATION

Timely fungicide applications pay due to the plant health benefits it provides.

 

HOW MUCH CARRIER?

Practical Farm Research data indicates that 15 to 20 gallons of carrier rate is the sweet spot. Always read and follow label directions
