[root disease]

Naturally fight against above ground-diseases (Botrytis and Didymella) and root or base rot diseases (Pythium, Phytophthora, Rhizoctonia and Fusarium).

Prestop® contains mycelia and spores of Gliocladium catenulatum strain J1446, a naturally occurring soil fungus, selected through Lallemand Research for its capacity to control a range of very important crop diseases.

The active fungus Gliocladium catenulatum strain J1446 operates through several useful modes of action:

  • hyperparasitism: production of enzymes which cause the breakdown of cell walls of plant pathogens.
  • competition: quick colonisation of root and aerial parts of the plant depriving pathogenic fungi of living space and nourishment. 

Composition: 2×108 CFU/g (320 g/kg of active ingredient) of spores and mycelium of Gliocladium catenulatum strain J1446. (CFU: Colony Forming Unit. Unit of measure for living microorganisms able to multiply).

Formulation: wettable powder

Organic culture: usable in organic production subject to certification body approval.

Harvest interval: none

Harmful residues: none

Storage: can be stored unopened for 12 months in a cool and dry place below +4°C. It is recommended that all of the contents of the package are used immediately once opened.

       1 kg bag


The most efficient way to use Prestop® is preventatively. The active microorganism survives in the rhizosphere and on the aerial parts of plants for several weeks, protecting them against pathogens.
