Blackberries

About two weeks ago I heard some reports of possible damage caused by broad mites Polyphagotarsonemus latus in caneberries in the mid-Atlantic region. So I ventured out and looked at several raspberry and blackberry growing operations in Maryland. I found one farm with a light to moderate infestation of broad mites in their raspberries. This operation was relatively small consisting of a little more than a ¼ acre or so of caneberries.

The recent weather has been damp with overcast skies and drizzle, which can lead to foliar diseases like botrytis and orange rust in brambles. Orange rust appears as blister-like masses of orange aeciospores on the lower leaf surfaces of blackberry plants, caused by fungal pathogens. Infection occurs after prolonged wetness, with temperatures between 43°F and 72°F.
