The movement of manganese in the plant and the practical consequences.
AbstractMovement of foliar applications of Mn was investigated. Mn applied to the leaf was translocated to other parts of the plant via the roots; in the leaf, upward movement predominated. Redistribution of Mn from the roots was insufficient to prevent Mn deficiency in the foliage formed after spraying; where the soil Mn supply was insufficient, repeated spraying was necessary. In wheat, oats and sugar-beet, spraying was best done as soon as Mn deficiency symptoms became evident, and again 4 weeks later. Control of marsh spot of peas was best achieved by spraying at mid-bloom and again just after flowering.-R.B. (Abstract retrieved from CAB Abstracts by CABI’s permission)
