Observed revenue difference = yield difference × stated crop price. Estimated return after treatment cost = revenue difference − $35/acre. Other costs that change with yield are not included; this is not whole-farm profit. Break-even = $35 ÷ stated price (7.692 bu corn, 2.773 bu soybeans), shown rounded. Plot differences use unrounded plot averages; field-trial differences come from the raw harvest files (fungicide/insecticide 480 ft vs. the next 480 ft). The $35 cost is applied only to fungicide/insecticide comparisons — not to seed-treatment or tillage results.
