Often gardeners observe how red currant leaves turn red, become covered with swollen areas, and then fold and gradually die off. The phenomenon is rather unpleasant, and it is more often associated not with a disease, but rather becomes a consequence of the vital activity of parasites - gallic aphids. Another reason is the development of anthracnose fungal disease. Let's find out what to do, if every now and then the red currant appears on the currant .
How to treat red spots on currant leaves?
If the cause in gallic aphids, which settles on the reverse side of the leaf and feeds on its juices, it is necessary to fight not only with it, but also with its peddlers - garden ants. There are many ways for this:
- aphids can be destroyed with soapy water, infusion of onion husks or Strela preparation;
- ants are driven out of the garden with "Garden Protector", "Fufanon" preparations, and can also be powdered with cinnamon or tobacco dust;
- to attract the ladybirds that eat aphids, you need to plant bright flowers next to the currant.
There are also several ways to fight if red currant leaves on the currant leaves are from anthracnose. It develops in conditions of high humidity, mushrooms perfectly winter over the remains of leaves under the bushes of currant and easily spreads with insects and water.
To determine that the red leaves appeared on this black and red currant from this disease, it is fairly easy - first, red-brown spots appear on the leaves, which eventually "spread" over the leaf, resulting in a reddish red or any other currant.
For a plant, the disease is very dangerous, since the leaves can fall off even with only a few red spots. First, the lower leaves are affected, which are closer to the wintering fungus, then the rest of the bush is gradually infected. The peak of the disease occurs at the end of July - August.
So, how to deal if there are red spots on the leaves on the currant:
- Every autumn you need to collect and burn all the fallen leaves, and soil under the bushes to dig up to 10 cm. Also all the weeds near the bush should be destroyed.
- If you find the first signs of anthracnose, you need to spray the shrubs with "Fitosporin". Pay special attention to the lower surfaces of the leaves. The treatment should be repeated in the autumn.
- In early spring and late autumn, treat the bushes with a 3% solution of nitrafen.
