Conclusion
Tercero Duo appears to delay senescence onset on Wheat (PSRI held steady within the window).
- PSRI change between T-5 and T+15: +0.009 points.
- Mean decline rate inside the window: +0.000 /day.
- Senescence Onset Date (SOD) estimated at 105 days from sowing.
- Canopy held within senescence-stable range for 16 day(s) after application.
- Fungicide profile consistent with extended photosynthetic activity (lower decline slope).

This metric tracks whether the treated plot maintains physiological activity for longer periods by detecting delays in senescence onset and comparing decline rates between subwindows.
