If the leaves of pears changed shape, began to curl, dry out, the shoots changed color, most likely, aphids parasitize on the fruit tree, which leads to a decrease in yield, sometimes even to the drying of the plant.

How to deal with aphids on a pear

  • Chemical - the use of chemicals: pyrethroids, neonicotinoids, organophosphorus compounds. Spraying with chemicals can only be done before fruit formation or after harvest. During the fruiting period, the use of chemicals is strictly prohibited. The most effective way is to spray with Kinmix until the buds swell, before flowering with Agravertin, after the fruit set with Iskra.
  • Biological - the use of drugs of biological origin, the treatment of trees and the soil under them, which will help save the harvest. Some insects feed on aphids: lacewings, ladybugs, wasps. You can plant them on leaves, tree branches. It is also advisable to grow mint, dill, yarrow next to pear trees, they attract insects that feed on aphids. It is necessary to destroy ants, since aphids live with them in symbiosis. The ant, especially the black one, leads to a greater dispersal of aphids.
