JUST PUBLISHED: Fungicide performance against Botrytis fruit rot

/ Kyle Blauer

The results of two fungicide trials conducted in 2022 and published in Plant Disease Management Reports in 2023 are presented here. In these trials, 20 unique products were evaluated for performance against Botrytis fruit rot (Fig. 1). After 5 weekly applications (Fig. 1), fruit were evaluated in the field (at-harvest) and postharvest after storage at room temperature for 10 days. Figure 2 shows the results. The full reports can be seen here (Trial 1, Trial 2).
