Cereals - Deformation
Ears of Cu deficient plants are often trapped in the sheath and emerge with white tips and blind spikelets.
Plants show dry, white and twisted or curled leaf tips (white tip). Young leaves wilt on their tips, whereas the basal leaves remain dark green.
Copper deficiency
Severe drought, heavy frosts and herbicide damage can cause blind ears, too.
Cereals - Wilting
Young leaves show dry, white and twisted or curled leaf tips (white tip). The basal leaves remain dark green.
The complete plant growth is stunted.

Copper deficiency
Cereals - Deformation
Ears of Cu deficient plants are often trapped in the sheath and emerge with white tips and blind spikelets.
Less severe symptoms may be seen as curved ears which do not ripen with an accumulation of the dark coloured melanin.

Copper deficiency
Cereals - Size reduced
Ears of Cu deficient plants show blind grain sites (blind spikelets) or poor grain formation. As the ears are lightweight they stand more upright than sufficiently supplied ones and give the plant a different habitus.
Copper deficiency
- Organic soils
- Chalky soils
- Sandy soils
- Reclaimed heathland
- High nitrogen applications
- Increased fertility (number of grains per ear)
- Better grain quality
YaraVita GRAMITREL
Cereals: 1 to 3 l/ha from the 2 leaf stage to second node detectable (Zadok's G.S. 12 to 32). Repeat applications at 10 to 14 day intervals, within this timing, if necessary. For autumn sown crops, an application prior to winter dormancy may also be beneficial. In addition, 1 l/ha from second node detectable to flag leaf fully emerged (Zadoks G.S. 32 to 39). Water rate: 50 to 200 l/ha. Seed Dressing: 3 to 6 litres per tonne.
YaraVita MANCOZIN
Cereals: 1 l/ha at 2 leaf stage to second node detectable (Zadok's G.S. 12 to 32). Water rate: 200 l/ha. For severe deficiency, increase to 2 l/ha or repeat at the above rate. For autumn-sown crops, an application prior to winter dormancy is strongly recommended. Seed Dressing: Typically 3 litres per tonne. Rate can be increased up to 6 litres per tonne if necessary.
