To combat the bud mite on currants, all summer residents, without exception, treat the bushes with hot water in early spring.
The method is foolproof if done in a timely manner. If the fact of pest infestation is obvious, then boiling water alone will not do. This is what experienced gardeners advise.
You can defeat the pest methodically and purposefully, depriving the tick of any chance of survival.
First step
Before planting a new seedling, stock up on a sufficient amount of hot water (temperature 60-65 degrees). Place the seedling in it, putting a bag on top or wrapping it in film. If pests live in the depths of the plant, they will not withstand such a bath and will run away. Important! There should be no leaves on the plant.
Step two
Regularly prune blackcurrants. Remove all old, black, suspicious branches and all shoots older than 4 years at the base.
Step three
Gardeners are often advised to cut off swollen buds, but experience and practice suggest that it is better to cut off the entire affected shoot or at least to a healthy bud.
Step four
Only after sanitary pruning of the bush does it make sense to carry out treatment with hot water. It is best to do this while there is snow and the temperature is about 5 degrees Celsius. Then the bush is sprayed with appropriate preparations. For example, "Prophylactin" is effective at a temperature of 4 degrees Celsius.
The next treatment is performed before budding. Use Fitoverm (air temperature not lower than +15) or Aliot (temperature not lower than +10).
