Highly selective biological insecticide aimed at suppressing butterfly caterpillars


Bacillus thuringiensis ssp. kurstaki  spores and crystals






Biological fungicide with preventive action


Bacillus subtilis

D-STOP is applied in:





D-STOP is a highly selective biological insecticide which affects the digestive tract of a caterpillar, right after it is ingested.


The active component consists of δ–endotoksin of protein nature which is synthesized by a bacterium during the sporulation. After protein crystal is ingested, it dissolves into toxic subunits and causes lysis of the cells of intestinal walls. Intestinal paralysis and cessation of feeding happens in a short time and caterpillars die after a few days.


The highest efficiency is achieved by treating the early stadiums of the caterpillar development (second and third larvae stadium). The application is recommended short after the active hatch of the caterpillar, while the plant material onto which the preparation is applied is still not heavily damaged.

F-STOP is applied:

F-STOP is a preventive fungicide. It prevents germination of spores (destroying germ tube), growth and development of mycelium. It creates inhibition zone on the treated surfaces, making development of pathogens impossible.

F-STOP is intended for spraying the roses from the ground during the intensive growth, so that it protects the newly formed leaves. In a period from the late autumn until February, when the growth and development of roses is slow, the preparation should be sprayed in longer time intervals. However, keeping the preparation present is of extreme importance. It is intended for spraying the apple trees prior to picking.


F-STOP  protects your crops from the causers of:

  • Powdery mildew
  • Collapse and wilting of vegetables, flowers and decorative plants
  • Mold in the fields and on stored fruit and vegetables.
D-STOP is not classified as dangerous. F-STOP is not classified as dangerous.
