Cavity Decay

Cavity Decay – plant disease Common name Cavity decay Causal agent It is usually caused by decay fungi in the hollow parts, especially after the tree faces some injury. The fungi enter through open wounds and cause rot, structurally weakening the tree. Symptoms & Signs Cavity decay in plants is characterized by a depression on the branches, trunk, or stems. The hollow areas may show fruiting bodies, such as mushrooms or brackets, as well as discoloration and softening. An overall decline in plant health is seen, with general symptoms of wilting and yellowing of the leaves. Depending on the intensity of decay, the tree may die back or fall during a storm. Transmission The fruiting bodies on the decayed cavities release spores that travel by air, water, or contact with tools to other trees. They enter through open wounds and stomata to start their lifecycle again in a new tree. Time of concern Throughout the year Common hosts Apricot Apple Plum Peach Juniper
