Lantmännen BioAgri develops and markets biological seed treatments for cereals, peas and carrots. These seed treatments are being used in Sweden, Finland and Germany today. BioAgri customers consist mainly of seed producers who, based on trial results, treat their seed with our seed treatments.

Lantmännen BioAgri’s biological seed treatments have the benefit of over ten years of intensive research, testing, and product development, initially at the Swedish University of Agricultural Sciences and subsequently at Lantmännen BioAgri itself.

The dressing agents Cedomon®, Cerall® and Cedress®, with the active substance Pseudomonas chlororaphis MA342, a naturally occurring bacterium in soil, have been available since the late 1990s. Products based on MA 342 can be applied to seed with standard seed treatment machinery.

Advantages of Cedomon®, Cerall® and Cedress®

  • Naturally occurring soil bacterium as the active substance in these products
  • Can be used in organic production
  • Biodegradable
  • Improve root growth
  • Increased harvest
  • Treated seed can be stored for 12 months without any loss of effect

The bacterium has several modes of action. For example, it competes with other microbes for nutrition and space.
