Pseudomonas sp. Proradix

The Bacterium Pseudomonas sp. Proradix is the active component of biological plant protection compounds for potatoes, vegetables and seeds. The term Proradix comes from the Latin „pro radice“, meaning “for the root”. And this is exactly where the soil bacterium populates after the plant has been treated.

Due to various impact mechanisms, the bacterium provides protection and optimal water and nutrient uptake. After application, the Pseudomonas-Strain works as follows:

It activates the plant’s own resistance mechanism. (Resistance induction)
It competes with soil-borne pathogens for root exudates and biosphere and comes through.
It produces a very potent iron-chelate (Siderophor)
It reinforces the root’s cell wall.

Thereby, a healthy and differentiated root system forms that helps the plant grow consistently and strengthens its resistance.

The Pseudomonas-Strain is a new description and administered with the Deutschen Sammlung für Mikroorganismen und Zellkulturen (DSMZ) under the name of Pseudomonas sp. Proradix (DSMZ 13134).

Pseudomonas trivialis

The living cells of the Pseudomonas trivialis-strain form the active component for the bacterial compound SALAVIDA, the biological soil enhancer for salad.

The SALAVIDA bacteria multiply on the root and grow along with it. They feed on root exudates and produce substances themselves such as iron-chelate which increases the soil fertility and microbial soil activity.

The positive influence on the soil root system promotes more intensive rooting with salad. This guaranties a better nutrient and water uptake. Simultaneously, stress on the plants from outer influence is reduced.
