PRESTOP WP

Effective protection for your greenhouse plants with a biocontrol solution
  • Biofungicides

PRESTOP WP is a concentration of mycelium and spores from the J1446 strain of Clonostachys rosea, a fungus naturally found in soil and decomposing organic matter.

The J1446 strain was produced by researchers at Lallemand Plant Care and was isolated due to its fungicidal properties, particularly against grey mould caused by Botrytis cinerea on strawberries, tomatoes, cucumbers and peppers, against gummy stem blight of cucumbers caused by Didymella bryoniae, and also against seedling damping-off and root diseases caused by a complex of pathogenic soil fungi on vegetable crops and ornamental plants (Pythium spp., Fusarium spp., Phytophthora spp. and Rhizoctonia spp.).
