Promotes Roots... Triggers Crop Defenses

Analysis (0-27-6 with 3.8% Zn & 1.5% Mn)

What Is It?

  • Seed dressing for application onto cereals, oilseed and pulses prior to seeding.
  • Unique formulation with high concentrations of Phosphorus, Potassium, Zinc and Manganese.
  • The Gel Rheology Technology™ keeps the highly concentrated product suspended and helps with seed adhesion and drying out.
  • The product is available in 10L jugs, 450L and 1000L IBC’s.

When & Why Use It?

  • Cold and wet conditions and when seeding into a dry soil.
  • High pH soils, heavy manure land, soils with low organic matter.
  • Sandy and light-textured soils.

What To Expect?

  • Primer Mn enhances secondary root development which maximizes the uptake of all nutrients.
  • Primer Mn triggers the crop’s natural defenses (i.e. Phytoalexins), which in conjunction with the fungicide seed treatment:
    • improves the quality and grade of the grains;
    • preserves yield.

Application Guidelines

  • Cereals: 3 mL/Kg of seed or 122 bu per 10L jug; 410L per 5000 bushel bin.
  • Oilseeds: 6 mL/Kg of seed or 73 × 50lbs bags per 10L jug.
  • Primer Mn can be used alone or in combination with other seed treatments. Check the best option for your targeted combinations (see compatibility charts).
  • Primer Mn can be diluted with water for a more uniform coverage onto the seed. Dilution improves the dry down time.
  • Primer Mn should NOT be used with liquid Rhizobia on pulses.
  • It is highly recommended to wash the seed treatment equipment with water after use.
