  • E0 is the theoretical fresh weight survival rate for the mixture of the first herbicide and the second herbicide
  • X is the measured fresh weight survival rate for the first herbicide used alone at the same dosage as that in the mixture.
  • Y is the measured fresh weight survival rate for the second herbicide used alone at the same dosage as that in the mixture.
  • Colby s Equation: We wanted to test whether mixing Diquat and Saflufencil would produce a greater effect than expected. To do this, we used Colby's equation. If the observed value of the mixture was greater than the expected value (i.e., E>E0), we could prove that the two chemicals had a synergistic effect when combined.
  • the parameter we measured was the percentage of dry field. After applying Diquat, the field was 24% dry compared to the control, while the crop was 40% dry after applying Saflufenacil. When we mixed Diquat and Saflufenacil in a tank, the entire crop in the field was 100% dry. Additionally, the expected efficacy (E) of the mix was calculated to be 54.5%.
  • Treatments were then applied the tank mix to the field containing peas and CHEAL (Chenopodium album) according to the directions on the label of Armory 240EC. Specifically, we sprayed 2.106 L/ha (1250 mL of treatment 1 + 856 mL of treatment 4) of the tank mix for treatment 5, 1250 mL/ha of treatment 1, and 856 mL/ha of treatment 2.
  • Table 5 shows the grams of active ingredient per hectare (a.i./ha) for each treatment.
