Boron Deficiency in Peach

Typical boron-deficiency symptoms are small, thick, misshapen, and brittle leaves carried on branches with short internodes. A water-soaked dieback is followed by excessive branching. Veins and midribs are pronounced and are often corky and red in colour. The bark may split and have pronounced lenticels. Reduced fruit set occurs. Fruit are often small and abnormal, with internal necrotic patches and sometimes without seed. Fruit may crack.

Peaches are also particularly sensitive to boron excess. Flower bud and flower shedding can both be caused by boron toxicity.
