Methodology
Channel 1405 1.4 maturity group soybeans were planted on May 25, 2018 at 160,000 seeds/acre in 15 inch rows. Aproach® fungicide was applied at R1 on July 30, 2018 at 9 ounces of Aproach® an acre in 20 gallons of water per acre to six strips. On August 7, 2018, three of the six strips were again applied with Aproach® fungicide at the same rate. Aproach® is a group 11 fungicide.
Results
In this trial, two applications of Aproach® fungicide increased yield by 0.66 bu/ac when compared to one application of Aproach® Fungicide. This yield increase was not significant. A yield increase of 3.25 bu/ac would be required for significant differences at the 90% confidence level. It is important to remember to rotate fungicides to decrease the chance of developing resistance.
