Raspberry blemish
Submitted by George Koepp on 6/28/2012
White drupelet disorder (sun scald)?? Client first thought it might have been powdery mildew, but the leaves are fine and this does not wash off the raspberries. Any other thoughts or ideas?

Her real question was "are the berries safe to consume?"

George:

This doesn't look like typical sun scald symptoms. I'm leaning toward powdery mildew, but would need to see a sample to look at microscopically to know for certain. If this is powdery mildew, I wouldn't have a problem eating the fruits, but I don't like to make formal recommendations on edibility in cases such as this. Folks can vary in terms of their reactions to fungi.
