The purpose of this study is to evaluate different fungicide carrier rates and their impact on yield and profitability.

2018 Multi-Location Soybean Fungicide Study - Carrier Rate

Common ground-applied water carrier rates range from 10 to 20 gal./A. Like other foliarapplied products, water volume with a fungicide can affect coverage, the amount of product capable of penetrating the leaf surface, and overall fungicide efficacy. Results from this study suggest that 20 gal./A. of water, when ground-applied with a fungicide, provides the highest yield increase and return on investment. If using a fungicide with only “contact” activity, a higher carrier rate may be more important than when using a pre-mix fungicide with multiple modes of action. This is because most of the commonly-used multiple mode of action fungicides, such as Stratego® YLD, include a “contact” component and a strobilurin component that has “locally systemic” movement within plant leaves.
