Fungicide Cost for Soybeans Per Acre 2026

Soybean fungicide applications cost $22–$45 per acre total in 2026. R3 (beginning pod) timing is the critical application window. Frogeye leaf spot, white mold, and sudden death syndrome are the primary targets.

2026 Cost Breakdown

Soybean fungicide product at R3: Miravis Ace, Aproach Prima, or Priaxor runs $20–$28/acre. Application adds $5–$12/acre. White mold pressure may justify a second application at R5 for an additional $25–$35/acre in high-risk fields.

Miravis Ace / Aproach Prima R3	$20–$28	+6%
Aerial application	$8–$12	+5%
Ground application	$5–$8	+4%
Second application R5 (white mold)	$25–$35	+7%
