The larvae are able to penetrate into the fetus and completely eat out the core of the bone. The affected fruit stops growing, matures early and falls off.
The sawfly is no less dangerous. The caterpillar first eats small fruits, and then penetrates into larger ones and eats the pulp. As a result, the fruits crumble and rot. Other insects are also of great danger. Together, they lead to the fact that the gardener may be left completely without a crop.

In autumn
After harvesting, the plums are treated with a Bordeaux mixture. To eliminate the moth and caterpillar, they dig up the earth in the near-trunk circle, remove foliage and weeds.
