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 6 replications. Drone Imagery was collected using a fixed-wing AgEagle drone on July 29 and September 14 of 2020.

Results

Fungicide application boosted yield by 1.23 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. The average GNDVI in fungicide-treated strips was higher in mid season drone image, but not statistically significant (Table 2). To better understand the efficacy of fungicides, more study at various locations and replication is needed.
