NoroTec Manganese/Copper
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.
The symptom of copper deficiency is well known as yellow tip disease. The youngest leaves turn pale in the tip and along the borders, fold and break to a whiplash. Ear formation will be incomplete and grain setting fails. A strong formation of green shoots is usual.
NoroTec Manganese/Copper shall be used at an early stage to achieve the best effect or when manganese and copper deficiency occur.
The low rate in the table below is used for prophylactic treatment and the high rate at symptoms of deficiency. The treatment may need to be repeated. The first treatment can be done at the same time as the weed control spray.
