What carrier rate should I use with my fungicide application?
When comparing the same rate of fungicide with different carrier rates, 15 and 20 gal./A. provided yield gains of over 6 Bu./A. and a positive return on investment (ROI) in 2017. A volume of 10 gal./A. was not high enough to achieve a positive ROI. A higher carrier volume can provide better coverage of the fungicide which protects more of the leaf area from disease as well as early senescence.
The purpose of this study is to evaluate different fungicide water carrier rates and their impact on yield and profitability.
