Use for

Use for

Cerall is a biological seed treatment that protects seeds against fungal diseases, hence supports growth and development of young cereal plants up to the five-leaf stage. Suitable for organic and conventional cultivation.


Seed-borne fungal diseases; Fusarium (Fusarium spp.), common bunt (Tilletia caries), glume blotch (Septoria nodorum) and foot rot (Microdochium nivale).


Winter wheat, summer wheat, spelt, rye, triticale.

How it works

How it works

Mode of action

Cerall offers both an immediate and long-lasting control on a wide variety of seed-borne diseases.

How does it work?

  • Cerall contains a high concentration of the P. chlororaphis strain MA342 bacteria, which produce metabolites.
  • After the application of Cerall, a biofilm is created around the seed.
  • The metabolites already present in Cerall have a direct inhibitory effect on various fungal diseases present on the seeds.
  • The bacteria present in Cerall will stay inactive when the seeds are stored dry.
  • After sowing, when water availability increases, the bacteria will become active and will rapidly start to multiply. This ensures that the seeds and first developing roots are quickly colonized.
  • Subsequently, the bacteria will start to compete with other pathogens for nutrients and space and continue to produce metabolites. This will further inhibit the growth of other pathogens.
  • Furthermore, the bacteria will stimulate the plant to start resistance reactions which, in turn, prevents other pathogens from successfully infecting the young plant.
  • Cerall not only protects the seeds against seed-borne diseases. It also empowers the plant to speed up seedling emergence and reduces abiotic stresses, which results in improved crop yields.
