Strawberry - Chlorosis
Symptoms
Manganese deficiency causes yellow-green intercostal chlorosis on young and medium old leaves. Green veins give the leaf surface a netlike appearance.
Zinc undersupply causes chlorosis on both younger and older leaves. Veins and the serrated leaf margins remain green.
Causes
Manganese and zinc deficiency
Deficiencies of both micronutrients occur often in some regions, occasionally even at the same time. They are hard to distinguish without further testing.
Iron deficiency can be a reason for chlorosis on the youngest leaves, while magnesium undersupply causes chloroses on older leaves.
Strawberry - Chlorosis
Symptoms
Manganese deficiency causes yellow-green intercostal chlorosis on leaves. Especially the medium aged, large leaves show distinct dark green veins and leaf margins. On the youngest leaves the chlorosis looks more uniform as the small veins are only slightly darker than the adjacent tissue.
Causes
Manganese deficiency on leaves
Symptoms can be confused with magnesium deficiency, but in this case interveinal chlorosis starts on old leaves.

Plant growth is stunted and fruits remain small.

Strawberry - Discolouration
Symptoms
Roots show a dull, dark brown discoloration. Their growth is poor.
Causes
Manganese deficiency on roots (right)
Strawberry - Chlorosis
Symptoms
Manganese deficiency causes yellow-green intercostal chlorosis on leaves. Especially the medium aged, large leaves show distinct dark green veins and leaf margins. With Zinc undersupply the leaves also show interveinal chlorosis, but the veins are less highlighted. The marginal area is diffusely tinted bronze to orange.

Manganese and zinc deficiency made worse by
- Organic soils
- Sandy soils
- High pH
- Cold wet periods
- Fluffy soils
Manganese is important for
- Stronger plants
- Healthier plants
- Gives plants more resistance to cold weather
