- Already in the first weeks of spring, when the currants have not yet come out of dormancy, they carry out sanitary pruning. Sick, dry and damaged branches are subject to removal. They must be cut very carefully so that no hemp remains, since through them the disease can spread to the entire plant.
- The branches of the currant bush should be located above the ground, and for this you need special supports. They will help you keep the branches intact, because when the berries begin to ripen, the load on them will increase significantly. It should be remembered that if the branch is damaged, there will be an additional opportunity for infection to enter the plant.
- In the process of caring for currants, it is imperative to remove the surface of the earth in the root zone. The rubbish that you collect in this place is subject to incineration. For the most part, it is here that favorable conditions arise for the development of pathogenic bacteria and pests.
- After waiting for the snow to melt, you can begin to loosen the trunks. As a result of this operation, air access to the compacted soil will improve.
- When the plants enter the growing season, fertilizing with nitrogen-containing fertilizers is carried out, which will accelerate the formation of new ovaries.
- Also for preventive purposes it makes sense for planting currants in autumn select suitable varieties that are characterized by maximum resistance to diseases and pests.

Pest control methods

Otherwise, mites will appear from them, which will begin to harm the rest of the currant bush. This can be avoided only if, already in the first weeks of spring, we begin to take measures to combat them. The most effective is considered mechanical removal of shootscontaining affected kidneys.
Further, they are subject to incineration. If there are many branches on the bush, then the summer resident is not always able to determine all the affected areas. Therefore, you should not limit yourself to cutting.
You can increase the effectiveness of the fight against this pest by using spraying currants 1% colloidal sulfur solution or 0.2% karbofos solution. Bordeaux liquid and other special preparations also show good results.
When spraying currants, you need to keep in mind that the drug works best at an ambient temperature of at least 20 degrees Celsius.
If the weather is colder on the day for which you have planned spraying, then after treatment the plant must be covered with plastic wrap. To consolidate the result, after 10 days, the bush must be sprayed again.
Currant aphid... You can detect the presence of this pest on the currant bush by the twisted and wrinkled ends of the branches. If you look at the back side, you can find a large number of small green bugs.
An effective means of combating aphid eggs is to treat the bushes even before the buds swell with a 3% nitrafen solution.
Spider mite... The harm from this insect to the currant bush is large-scale damage to the leaves, which negatively affects the vegetation of the plant. Already in early May, spots of a whitish or red-brown hue can be seen on the leaves.
Looking at the underside, you can find the tick itself. An effective method of dealing with this pest is to collect damaged leaves and burn them. It is also useful to combine it with spraying with a 50% solution of karbofos.

Blackcurrant Sawer and Willow Scale
The sawmaker needs to pay special attention, since it is not always possible to identify him in time due to his hidden habitat... It is possible to understand that the currant is affected by this pest after the appearance of sawfly larvae, which grow inside the ovaries and berries.
This usually happens the moment they leave their hideout. A logical consequence of this is the fall of the berries, as a result of the sawfly pupae fall into the soil, where they remain for the winter.
To avoid next year the defeat of currants by this pest, it is necessary in autumn or early spring dig up the trunk circles... In addition, spraying with a 0.2% chlorophos solution is beneficial.
Willow shield... This insect uses branches to lay eggs of red-purple color, which are masked by the shields of the dead individuals. Already during the flowering of currants, larvae hatch from the eggs.
As they grow, they form a scutellum, over time they harm the plant, using the juice of young shoots as food. This makes the currant bushes weaker, which in some cases may result in their complete withering away.
You can protect currants from damage by larvae by spraying before budding with 3 percent nitrafen paste solution... An effective measure is brushing the eggs off the branches. In cases where too many pests are found on a branch, it makes sense to cut it and burn it.
Currant goldfish... The appearance of this pest leads to the drying of the shoot starting from the top. This is due to the fact that beetle larvae choose it as a wintering place. Therefore, it is very important to prune branches where there are beetles in early spring.
Otherwise, the larvae will eat their core, eventually go down, and then the shoot will die. It should be borne in mind that young shoots are of the greatest interest for the pest. Therefore, it is necessary to take measures to combat it as early as possible, since the future of the entire bush depends on it.
