How it works

How it works

Mode of action

The bacteria Pseudomonas chlororaphis, present in Cerall, multiply on the seed and compete with pathogens attached to the seed. The bacteria produce substances that have a lethal effect on the fungal diseases on the seed. After sowing, the Pseudomonas bacteria continue to multiply. On the roots of the crop, the growing bacteria compete with the pathogens for space and nutrients, inhibiting pathogen development and thus protecting the roots and the plant. The bacterium induces systemic resistance, this strongly increases the defense capacity of the young plants. Growth is especially promoted under stress conditions.
