Use for

Use for

Cedress is a biological seed treatment that protects seeds against fungal diseases, hence supports growth and development of young vegetable plants. Suitable for organic and conventional cultivation.

Diseases

Seed-borne fungal diseases; fusarium wilt (Fusarium spp.), grey mold (Botrytis spp.​), blight (Ascochyta pisi​). Controls also Acrothecium rot (Pseudocercosporidium carotea).

Crops

Carrots, peas.

How it works

How it works

Mode of action

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

How does it work?

  • Cedress contains a high concentration of the P. chlororaphis strain MA342 bacteria, which produce metabolites.
  • After the application of Cedress, a biofilm is created around the seed.
  • The metabolites already present in Cedress have a direct inhibitory effect on various fungal diseases present on the seeds.
  • The bacteria present in Cedress 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.
  • Cedress 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.
