Question: prunus lusitanica
at the base of the stem a part has rotted and detached and I have 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 wood rod, which has infested the stem of your plant; often these larvae are in small numbers on the plants, and to find them it is necessary to remove the gelatinous resin produced by the plant and check that somewhere there is an entrance hole for the larva. Then foam insecticides are used, to be inserted in the tunnel, or the hole is closed with putty.
