Zinc deficiency

Oireet
Affected plants are paler in colour than normal and the leaves have a purplish tint. Necrotic spots (often light brown with dark margin) occur on the older leaves. Growth is also reduced due the affect of zinc on chlorophyll function. Internodes are shortened.

YaraVita GRAMITREL

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.
