Research

The objective of this study was to evaluate the effects of fungicide timing and cold storage on post-harvest fruit rot caused by Botrytis cinerea in raspberry. Applications of fungicides Elevate 50WG and Switch 62.5WG to red raspberry prior to harvest were evaluated for post-harvest control of fruit rot. Fungicides were applied 3 times during bloom only, 3 times pre-harvest (post-bloom) only, or 6 times full season (bloom through harvest), and symptomless fruit (at harvest) were incubated in either cold storage or at room temperature.
