Farming Smarter staff applied the insecticides at 40 L/acre water volume at half, normal, and double label rates of each insecticide, using CO2 propelled hand booms. The middle 2 meters were sprayed, leaving a 2-meter buffer on either side of the plots. Spraying occurred when the larvae were actively hatching.
Farming Smarter closely collaborated with Alfalfa Seed Commission to time the pesticide application appropriately. Plots were swept right before spraying and larvae were counted. This was repeated at 4, 7, and 11 days after application (DAA). Yield and dockage were gathered from the middle 2-meters of each plot (treated area).
Statistical analysis was completed using a linear model with ANOVA statistics, using 95% confidence, to assess treatment effects. Table 1 outlines the timeline of each research activity.
