Pseudomonas chlororaphis

The soil bacteria Pseudomonas chlororaphis is the active microorganism in Cedomon®, Cerall® and Cedress®. The bacterium has undergone studies in accordance with the EU directive EEC 91/414. In October 2004, the bacteria was approved for use within the EU and listed on Annex I. In October 2014 an application to reinclude the bacteria into Annex I was submitted. S

Several factors are involved in the mode of action:

Pseudomonas chlororaphis

The effective mechanisms involved can be briefly described according to the following:

  • Competition for nutrients and space
  • Growth stimulation
  • Induced resistance (the plant’s own immune defences are strengthened)
  • Antibiosis (secretion of biochemical products onto the seed in the soil)

Stimulates growth

The products stimulate early development in the plants. Recent studies indicate that the bacterium stimulates root growth. A good start makes the plant viable and more resistant. to different forms of stress.
