NoroTec Manganese
Manganese deficiency gives “grey-spot disease” in cereals. The leaves get grey to brown spots on the lower part and often the leaves breaks in the middle, decay and dye. The grain setting will be weak and green shoots develop. Dicotyledonous crops get yellow veins, often with dark spots between the veins.
NoroTec™ Manganese shall be used at an early stage to achieve the best effect. Experiences have shown, that sandy soils, high pH, organic matter and after cold, wet weather are conditions favouring manganese deficiency. The most susceptible crops are oat, wheat, rape-seed, sugar beets and potatoes. Peas and barley are less susceptible, while rye has a relative little need of manganese.
Content per litre:
150 g manganese, 80 g sulphur.
The content is chelated.
Recommended dosage rates and time of application:
- Cereals - 0,5 l/ha at rsk of deficiency (3-4 leaves-tillering),
1,0 l/ha at deficiency (3-4 leaves-tillering).
- Sugar beets - 1st spray: 1,0 l/ha (6-10 leaves),
2nd spray:0,5 l/ha (after 10 days).
- Potatoes - 1st spray: 1,0 l/ha (2-3 weeks after emergence),
2nd spray: 0,5-1,0 l/ha (before flowering).
- Rape seed – 0,5 - 1,0 l/ha (4-6 leaves - before flowering).
- Peas, beans - 1,0 l/ha (esant 4-6 leaves).
Amount of water (l/ha) - 200-300.
