/ Kyle Blauer

The results of two fungicide trials conducted in 2021 were just published in Plant Disease Management Reports. In these trials, 20 unique products were evaluated for performance against Botrytis fruit rot (Fig. 1). After 5 applications (Fig. 2), fruit were evaluated in the field (at-harvest) and postharvest after storage at room temperature for 10 days. The figure below shows the results. The full reports can be seen here (Trial 1, Trial 2).
