Active ingredients in the fungicide used in this trial:
In conclusion, I found very little disease pressure and after studying these results, it’s clear to see fungicide played a large role when comparing the check strips (with no fungicide applied) to fungicide applied at V6 and R1. In my opinion, the fungicide contributed to the slowdown of respiration in the corn plant (during the hot nights) leading to the abnormal increases in the results.
There wasn’t much yield advantage between applying fungicide at R1 only compared to at V6 AND R1. I’m not sure the two passes through the field paid for themselves when comparing.
