{Carya illinoensis}

Boron Deficiency in Pecan

Small, water-soaked areas develop on otherwise normal leaves. These areas turn purplish and then a reddish brown. As boron deficiency becomes more severe, more spots appear but they do not coalesce. The lower leaves on the rachis develop normally but the distal ones become small. Internodes are short and the growing points die back.
