Brand: Lallemand

LALSTOP K61 WP

LALSTOP K61 WP is a preventative biofungicide built on a naturally occurring, live bacterium that readily colonizes plant roots. It thrives in the plant rhizosphere for several weeks, giving plants a strong start for vigorous growth and development. It is designed for growers who want reliable, residue-free protection that fits into Integrated Pest Management programs and organic production.

LALSTOP K61 WP is applied as an aqueous suspension and protects vegetables, fruits, and ornamental plants against damping-off, wilt, and root rot diseases. It can be used via growing media treatment, drip irrigation, drench or spray onto the growing medium, dry seed treatment, and bulb and cutting dip. It works equally well in organic, mineral, and artificial growing media as well as field soils.
