How to treat currants from aphids: chemical and folk remedies

The content of the article



Colonies of small insects cause irreparable harm to currant and other fruit bushes: the tops of leaves twist, inflorescences fall off, young shoots dry and fall off, branches fall to the ground. All this entails a decrease in yield and the development of various diseases, so it is important to respond to aphids in a timely manner.

How to deal with aphids on currants

The pest activity peaks in May-June, while aphids remain active throughout the summer period. It actively reproduces and gradually populates the entire garden. The life cycle of an insect is as follows:

  • in early spring, new individuals emerge from the laid eggs;
  • they begin to multiply rapidly, spreading more and more in the garden;
  • the wingless form of pests occupies young, tender leaves, buds and shoots, pierces them with a proboscis and sucks out the juice;
  • when an excessive number of aphids occurs on a plant, it dries and dies, which necessitates the birth of a winged form of pests;
  • individuals fly to neighboring fruit bushes and continue to destroy the garden;
  • in the autumn, aphids lay eggs that hatch for the next season.

The appearance of a pest in the garden is indicated by swollen, twisted into tubes, reddened currant leaves. If you turn the young leaves of culture, on the inner side will be visible accumulations of larvae. As a rule, two varieties of aphids settle in the garden, each of which prefers a certain variety of berries: gall (leaf) – white and red, gooseberry (shoot) – black. The table below shows the recommended measures for pest control at different periods.
