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.
Plant and soil analysis are recommended.

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

Manganese deficiency made worse by
- Organic soils
- Sandy soils
- High pH
- Cold wet periods
- Fluffy soils
Manganese is important for
- Combats chlorosis
- Prevents premature leaf fall
- Gives healthier greener plants
