Manganese sulfate 32%

On leaves, manganese deficiency is manifested by a slight chlorosis internervuraire. At first, it may be confused with iron deficiency. Symptoms begin with a light chlorosis of the young leaves and ribs in adult leaves. The leaves develop dark spots and necrotic areas along the veins. A purplish luster may also appear on the upper leaf surface. Grains such as oats, wheat and barley are extremely sensitive to manganese deficiency. They develop a slight chlorosis and gray speckles that extend and converge. Eventually, the entire leaf that withers and dies.

Good observation of the symptoms must be sufficient to characterize the deficiency.

Stage of appearance: In severe cases it can start as early as 3-leaf stage, but the most common is the beginning stage of the run (late tillering to 2 knots).

Form in the plot

Affected plants are divided into irregular homes
• areas where the soil is blown are most affected.
Symptoms may be localized in bands related to tillage and / or wheel arches. Vegetation is sometimes greener on packed areas (headlands, wheel arches).

plant

Sometimes the plants have a collapsed port withered soft. They crash to the ground and show symptoms of verse in every way.

Corn on the internodes are shortened, weak root system and a very poor fertilization.

sheet
In young and middle leaves, white to beige withering aligned between the ribs, especially on the curvature of the sheet is observed. This phenomenon appears in the most severe cases, it is more common on barley.
Older leaves are affected first, and are usually completely dry. When the deficiency is early (so serious) all leaves are gradually affected and plants may disappear.
Risk situations

     Highly aerated soils, soufflés (bad contact root cellar)
     Soils rich in MO (> 4%) who received organic inputs (compost, manure) massifs.
     Acid soils whose pH has been increased too liming (pH> 7.0)
     Fall and winter low rainfall favoring implantation blown soil and maintaining this state for winter conditions.

 
harmfulness

In the most serious (early deprivation) cases culture can be destroyed in the most affected households.
curative solutions

Foliar applications are effective if they intervene quickly dice the onset of symptoms (current tillering to early stem elongation). All products are equivalent, provided they make by passing the dose of 500 g / ha minimum Mn. Bring foliar fertilizers containing only manganese.

Dose contribution:
- 1000g to 1500g / ha Mn metal early onset which can be at the 3-leaf stage (in the worst case).
- Renew the contribution a month after the first intake.

- In cases of severe deficiency, 3 inputs may be necessary, the third will be made aware bolting
