This article will discuss in detail what should be included in autumn currant treatment for pests and diseases. It's important not only to spray properly, but also to prune the bush and protect it from frost. These tips are relevant for caring for both black and red currant bushes.
Main autumn processing activities Treating these berry bushes requires the use of strong and toxic chemicals. In principle, folk remedies are also possible. However, the latter should only be preferred if the currants grew without problems this year. If the bushes are attacked by diseases or pests during the season, the treatment must be strong and thorough.
How to spray
When spraying, the first step is choosing the right product. This should be based on the diseases and pests already present on the plant or those whose prevention you want to prioritize. It's also important to remember that spraying should be done in clear, windless weather; otherwise, it won't be effective. Furthermore, the plant's growth cycle must be taken into account.
Stages of currant spraying during one year:
- It goes without saying that spraying is essential in the spring. Moreover, the first treatment should be done before the buds open.
- When the bush is in the active flowering stage, it also needs to be treated, but with less powerful preparations.
- After flowering, a weak but necessary treatment is also carried out.
- Autumn treatment is carried out only after the harvest, and it is essential to do this before the onset of frost.
If we speak about a specific technology, then you'll need to prune out the top shoots before the buds open. If you see traces of a thick, light-colored coating on the bush, this is a sign that powdery mildew mycelium has overwintered on your currants. Treatment for this disease should be carried out immediately, before the fungi emerge from the spores and begin to multiply.
The video shows in detail what goes into treating currants for pests and diseases in the fall. However, the first stage of bush care is early spring treatment, and this is when bud mites can spread. If they are noticed, all damaged parts of the plant should be removed and the bush should be rejuvenated as much as possible. If anthracnose, rust, or other spotting is detected, spraying with a single product is recommended, regardless of the season. In this situation, treating currants for pests and diseases in the fall with copper sulfate, iron sulfate, or Bordeaux mixture is recommended.
What preparations should be used for autumn pest control:
- 0.3% copper chloride solution.
- 1% Bordeaux mixture.
- 2% nitrafen.
- 0.2% malathion.
In this case, natural folk remedies that are excellent for preventative treatment include wormwood infusion, onion peel or garlic infusion, tobacco or calendula.
How to process correctly
Autumn treatment of black or red currants differs significantly from spring treatment. Specifically, in preparation for winter, affected parts of the bushes must be removed and burned, along with all the foliage underneath. Spraying should be carried out in cool, clear, windless weather.
The treatment should be carried out twice, separated by two weeks. Additional feeding of the treated bushes is also essential in preparing them for winter. If the gardener carries out all fall treatments correctly, they will be able to harvest large, sweet berries the following year without much effort or investment.
About currant pests and how to control them
To choose the most appropriate and specific method for treating currants in the fall against pests and diseases, it's important to carefully inspect the plant in the fall and determine which specific pests need to be addressed or what preventative measures are needed for a particular bush.
Spider mite
This parasite is often found on the underside of blackcurrant leaves. It can be seen along a thin woven webAt the beginning of the infection, light spots appear on the leaves, which then spread, and parts of the leaf become discolored. This eventually leads to the leaf taking on a marbled appearance, which then dries up and falls off.
The pest actively spreads in hot and dry weather. It overwinters under fallen leaves and in the topsoil. Therefore, be sure to remove leaves from under currant bushes for the winter and loosen the soil under the bushes.
Spider mite treatment:
- Spray with Fitoverm according to the instructions. Remember that this is an active chemical and must be applied safely.
- A common folk remedy is an infusion of onion peels. To do this, brew 100 grams of onion peels in five liters of water. After five days, strain the solution and spray it on the bushes.
Aphid
The parasite can also be seen on the undersides of leaves and at the tips of shoots. The infestation causes the leaves to curl, and ants often infest the affected areas. If the plant is left untreated, the leaves will dry out and die. In the fall, be sure to collect and burn all the leaves. However, the danger of this pest is that aphid eggs can overwinter on bare bushes.
Aphid control:
- Spray according to the instructions with Fitoverm.
- Mustard powder has proven to be an excellent folk remedy. Dissolve ten grams of white mustard powder in a liter of water, let it steep for several days, and then strain. Dilute the solution five times with water before using it for spraying. You can also make an infusion of garlic, tobacco, and even orange peel for this purpose.
Berry sawfly
This pest is unique in that it attacks berries. They ripen earlier, but become tasteless, small, and ribbed. The sawfly pupae remain in the top layer of soil directly beneath the bush during the winter. Therefore, in the fall, it's necessary to remove the leaves and further loosen the soil.
Treatment against berry sawfly:
- Throughout the season, it's essential to destroy infected berries. Pay particular attention until mid-July, as by late summer, the sawfly has already gone into hibernation.
- The best time to spray currant bushes against this pest is in the spring. For example, you can use "Karbofos" or another similar product.
