Abstract

Manganese and zinc deficiency symptoms on grapefruit leaves can be corrected by foliar spraying with these nutrients, but spring applications in desert areas will not prevent symptoms from reappearing on the new flush of leaves in the fall. Both spring and fall applications are recommended in desert areas, after the new flush of leaves has expanded to at least two-thirds normal size.
