Methodology
This experiment was conducted at Douglas county. Soybeans were planted on May 22, 2020 at a population of 160,000 Seeds/acre in 30-inch rows. Stratego YLD fungicide was applied at R3 growth stage of soybean with the rate of 4 oz/ac in 90-foot-wide strips, which had 5 replications. Drone Imagery was collected using a fixed-wing AgEagle drone on July 29 and September 14 of 2020.
Results
Fungicide application reduced yield by -0.15 bu/ac on average, but the difference was statistically negligible (Table 1). GNDVI is a scale that ranges from -1 to 1 and was computed using drone imagery. GNDVI values closer to 1 indicate improved plant health and yield, while lower values indicate the opposite. To better understand the efficacy of fungicides, more study at various locations and replication is needed.
