Raspberries - Chlorosis

Symptoms
Interveinal chlorosis occurs on older leaves. With ongoing deficiency the chlorotic tissue turns necrotic brown and mature leaves die off. Growth is stunted.

Reasons
Manganese deficiency Suggested range in leaf tissue is 80-300ppm. In acid soils Mn availibility is increased and may cause toxicity, as well as oversupply due to boron-containing fungicide. Plant and soil analysis are recommended.
