Boron Deficiency in Avocado

There is gradual death of both the apical and axillary growing points. The leaves are distorted, somewhat crinkled, often lanceolate, and have necrotic patches. The midrib and main veins on the lower surface of the leaves frequently split and become suberized. The young twigs may swell and show internal corky pockets.
