Raspberry diseases and what you can do about it
The joy of raspberries in the garden is quickly clouded when the shrubs get sick and bear little fruit. This will help you to see what your raspberries are suffering from and how you can fight the diseases.
The most common diseases of raspberry
Symptoms of red root rot
If your raspberry produces only weak buds, you should look for the roots. If these are brownish to gray discolored, it is root rot.
It is created primarily by waterlogging. The rain or pouring water can not drain properly. As a result, fungi develop that affect the roots and later the rods.
When planting, make sure that the earth is completely loose. Since the fungal spores spread in the garden, it helps little to implement the plants. Cut off affected rods and dispose of them.
The Ruthenia
This is also a fungal disease. It mainly affects perennial shoots. The fungus attacks the rods so that they are no longer supplied with nutrients. They die and have to be removed.
As a preventative measure choose a light location. Thin the shrubs regularly, because too many rods favor the spread of the fungus. Remove weeds under the bushes regularly.
Autumn raspberries are rarely affected by the disease. Since the rods are cut back immediately after harvest, no perennial shoots remain on the shrub.
fruit rot
They recognize this fungal disease by the fact that the fruits begin to mold on the bush. The damage begins at the flower.
Collect all affected fruits and dispose of them. Spraying with plant broths from field horsetail can help. Often, the only option is to administer chemical fungicides.
Anthracnose
If there are small, purple spots on the young rods, it can be the focal blotch. Although this disease is common, it usually does not affect crop yield. Simply cut off infested rods.
Tips & Tricks
When planting new raspberries, look for mushroom- and disease-resistant varieties. There are now a few strains on the market that are much more robust and better able to handle pathogens.
