Boron deficiency-Sugar Beet

Symptômes
The symptoms start on younger leaves which get crinkled and brittle and remain small. Later they get twisted and black or brown corky spots appear on the petioles. The younger leaves show wilting symptoms and become subsequently black and dry. The older ones show wilting symptoms with chlorosis between the leaf veins. The growing point dies off ("heart rot") and also the beets get dry and die off. After rainfall, the plants may recover and form lateral leaf rosettes.

Raisons
Boron deficiency. Calcium deficiency also affects the youngest leaves and the growing point first with chlorosis, but different to B deficiency, wilting symptoms are not described for Ca deficiency, and chlorosis and necrosis start on the leaf margins.

Symptômes
The beet shows a deeply ridged and rotten surface. Necrosis of the beet top is common with Boron deficiency.
