Molybdenum deficiency Molybdenum deficiency occurs in highly acidic soils that are strongly weathered and leached and in soils where the element is in an unusable form. Mo deficiency causes considerable yield losses.

Symptômes
Several leaves, different in age, show a light green to yellow chlorosis, spreading irregularly over the leaf blade.

Symptômes
Several leaves, different in age, show a light green to yellow chlorosis, spreading irregularly over the leaf blade. The bottom leaves additionally develop marginal necrosis. Small brown spots appear within the chlorotic zones. Some of them enlarge and become whitish, scorched, seamed by a fine dark line.
