Raspberries - Deformation
Symptoms
Stunted growth, misshapen leaves, poor fruit set. Mature leaves show interveinal chlorosis with subsequent scorching of canes. Splitting of stems may occur occasionally.
Causes
Boron deficiency (right)
Boron deficiency can also be induced by low water uptake or other nutrients such us Ca, K, N or P. Leaf levels of 20-80ppm are normal. Oversupply may cause B toxicity.
