We continued our examination into Botrytis (gray mold) infections coming in and out of storage. Read about our findings and how to move forward accordingly through the application of pre-harvest fungicides.
We noticed increased incidence and severity of foliar blotches in apple blocks this summer. Read about the ways in which overhead cooling works to combat this challenge.
