Studies on the symptomatology of wood pitting disease (legno riccio) of grapevines in Bulgaria


, : Studies on the symptomatology of wood pitting disease (legno riccio) of grapevines in Bulgaria. Gradinarska i Lozarska Nauka 11(4): 106-114

Leaf symptoms of wood pitting disease were similar to those caused by fan leaf virus and in the later stages resembled deficiency symptoms. The disease retarded growth vigour and depressed shoot maturation, thereby reducing frost resistance and the life span of the plants.
