Application

Shake (stir) the Siarkomagpackage before use to ensure equal distribution of the suspension throughout the container. Apply foliarly in the form of water suspension or together with urea, monohydrate magnesium sulfate, foliar fertilizer and a proper tested pesticide in the lower dose recommended by the manufacturer.Apply the spray with the mixer turned on.

Preparation of the working solution:with simultaneous application of all permissible components – in the sprayer tank (filled up with water to around 2/3 of the capacity), with the mixer turned on, dissolve, one by one, the monohydrate magnesium sulfate, urea, Siarkomag, another foliar fertilizer and pesticide, according to its application instruction. Fill up the tank with water. Use the liquid immediately after preparation.Apply the spray with the mixer turned on.

Technical Details & Test Data

Significance

Sulfur and its significance :

  • conditions the correct utilization of nitrogen fertilizers and nitrogen transformation in the plant.
  • increased immunity to diseases and vermin
  • constitutes an important building block for protein amino acids
  • takes part in carbohydrate and fat formation processes
  • participates in photosynthesis, chlorophyll synthesis and many other structural compounds.

Magnesium and its significance:

  • basic building block of chlorophyll – plays a key role in the photosynthesis process.
  • indispensable for synthesis, transport and storage of stock substances
  • activates the operation of a number of enzymes
  • participates in the plant’s energy processes as a connector of the enzyme with the energy carrier (ATP)
  • helps to keep the right structure of ribosomes
  • controls the hydration of biocolloids, thus influencing the plant’s water management
  • strengthens the plant’s resistance to diseases

Symptoms of sulfur deficiency :

  • impeded plant growth
  • fragile and thin stalks
  • chlorosis of young leaves and shoot ends (distinctive whitening may occur)
  • spoon-shaped leaf bending
  • impeded lateral growth of leaves
  • formation of sterile ears.

Symptoms of magnesium deficiency:

  • wilted shape of the plant
  • marble-pattern chlorosis of older leaves
  • necrosis and dying of older leaves
  • fall of lower leaves
  • “pearl-like” or “bead-like” deformation of cereal plants
  • purple discoloration between the nerves in cherry leaves, later turning into necrosis.
