Conclusion
Tercero Duo produced a measurable canopy expansion on Wheat during the T-5 to T+15 window.
- Net NDVI change between T0 and T+15: +0.029 points (gain of 2.9% of canopy reflectance).
- Largest response observed in the interval From T+5 to T+10, with a growth gain of +0.020.
- Smallest variation in From T+10 to T+15 (+0.003), indicating canopy stabilisation in that subwindow.
- Canopy remained stable for 9 day(s) after application (low intra-day variability under the stability threshold).
- The response profile is consistent with a fungicide protective effect: the early post-application interval shows the strongest positive signal.

Canopy Level (NDVI) — daily series
T-5 → T+15
This metric tracks canopy expansion before and after the application date by comparing NDVI growth rates within a tight 5-day pre / 15-day post window centered on T (application date).
