Additionally, you can treat the trees with the HOM preparation, diluted at a rate of 40 grams per ten liters of water. When the pear tree's buds begin to open, treat it against mites using colloidal sulfur.

In May

Let's move on to the timing and recommendations for spraying trees and shrubs against pests in the spring. As for May, additional treatment will be necessary during the flowering period. At this time, there is a risk of damage to the tree by leaf roller caterpillars. Any biologically active product can be used for spraying.

After the trees finish blooming, they should be checked for scale insects. If the pest is detected, additional treatment is carried out with an appropriate chemical, which can be purchased at a flower shop. If moths are found on the plants, Fozolon or Rogor-S can be used for treatment in May.

Trees may become infested with mites during the first month of summer, in which case they should be treated with colloidal sulfur or similar products. Traditionally, "Skor" or "Agat-25" are used for stool mites, but copper sulfate can also be used.

It's also worth remembering that after the harvest, the trees are prepared for winter. This includes additional treatment with synthetic pesticides and spraying fruit trees with pome fruit infusions.
