Question: prunus lusitanica
at the base of the stem a part is rotted and detached and I found the presence of a gelatinous thing with a color equal to the resin. what should I do?
Answer: prunus lusitanica
it could be a rodilegno, which has infested the stem of your plant; often these larvae are few in number on the plants, and to find them it is necessary to remove the gelatinous resin produced by the plant and verify that somewhere there is an entrance hole for the larva. Subsequently, foam insecticides are used, to be inserted in the tunnel, or the hole is covered with mastic.
