Questions on: Red Currant

Ron Smith, Horticulturist, NDSU Extension Service


Q: My red currants and gooseberries put on fruit, but then when they start to ripen the berries get worms. What can be done? I am also getting worms in my rutabaga. (Bottineau, N.D.)

A: The currants and gooseberries are being attacked by the currant fruit fly. To control, spray them with Sevin when the blooms are about 80 percent withered and fallen. Repeat in seven to 10 days.

Follow excellent sanitation practices. Clean up all fallen fruit, and cultivate the soil around the plants.


Q: Can you please tell me what disease is attacking my Alpine currant? (Richville, M.N.)

A: The currant has symptoms of anthracnose, a fungal disease of the foliage mostly, that gets started in early spring. To control, follow good sanitation procedures by cleaning up all leaves this fall. Next spring after leaves have unfolded spray with Bordeaux mixture. Repeat in three weeks. Be sure to cover both leaf surfaces, using a good spreader.


Q: I have enclosed some branches from an Alpine currant hedge that has been in place for four years. This year it has been browning and looking very poorly. I tried spraying with a systemic fungicide containing Daconil but it didn't seem to help. Can you please tell me what to do next? (Detroit Lakes, Minn.)

A: Wow! Anything that looks that bad I would cut out this fall and hope for a better show next year. If there is no improvement, I'd suggest dumping.
