Primo Ultra

Multi-Action, Premium Soybean Inoculant



Give every soybean seed the best possible chance

Primo Ultra offers up to two times more rhizobia per seed, with multiple strains (Brradyrhizobium japonicum), for consistent performance. The addition of plant health-promoting chemical compounds enhances the soybean root mass, allowing plants access to more nutrients, creating more growth and greater yield potential.

Benefits

  • Lower rate allows you to treat more units with the same amount of product
  • Can be treated via traditional methods or enabled with FlexConnect inoculant delivery system
  • Performs well even in harsh conditions
  • Extended planing window
  • Bulk packaging to treat up to 1000 units

Primo GX2

Primo GX2 is an in-furrow, multi-action granular seed inoculant that brings more nitrogen to the plant and performs well in harsh planting conditions. When used under these conditions, Primo GX2 helps ensure improved water and nutrient uptake for healthier plants by combining high levels of nitrogen-fixing rhizobia with an organic biological growth promoter.

The formulation maximizes the effectiveness of the rhizobia, boosting plant health from the start and enabling the seed to reach its full genetic potential to maximize yield. Primo GX2 leads to increased seedling vigor, improved stand count, enlarged root mass development and additional nodulation.

Benefits
  • Increases seedling vigor - noticeable height difference during early growth stages
  • Improves stand count for quicker canopy development and increased yield potential
  • Enlarges root mass development, leading to improved water and nutrient uptake
  • Additional nodulation means improved nitrogen uptake to increase the potential number of pegs and pods that are set
Primo Power CL

Primo Power, a higher concentration liquid seed inoculant for peanuts, is designed to maximize plant growth with specially selected strains of rhizobia. Primo Power CL enables healthier plants right from the start and maximizes yield potential with increased nodulation.
