Prestop contains mycelia and spores of Gliocladium catenulatum Strain J1446, a naturally occuring soil fungus, which is capable of providing a number of very useful disease control benefits to a wide range of cropping situations.
These include action as a hyperparasite, production of enzymes which cause the breakdown of plant pathogen cell walls and deprivation of pathogenic fungi – regarding living space and nourishment – by colonizing the surface of roots and aerial parts of the plants.
These functions are supported by indirect effects where stimulation of the plants’ own natural defence systems takes place.
To ensure best control of diseases apply PRESTOP in a protectant programme of treatments before infection occurs.
PRESTOP can give effective control of a wide variety of plant pathogens:
