Fungicide Activator

CHAPERONE™ is a highly concentrated fungicide activator with Performance Enhancer Technology and proven efficacy in activation of and residual control of contact, systemic, and translaminar fungicides.

CHAPERONE™  is designed  to enhance the performance and efficacy of fungicides and help increase the percentage of diseases controlled, driven by the below properties:

1) Non-ionic Surfactant: Carbohydrate-based with excellent humectant-adherent-sticking properties that reduce the surface tension of the spray droplets. These properties promote greater surface contact on the leaves to get improved coverage of fungicide spray droplets as well as increased absorption and translocation of fungicide once they reach the cell membrane of the fungi.

2) Penetrant: Modifies the waxy cell wall of fungi, ensuring faster and more efficient penetration of fungicides through the intercellular walls of fungi. This allows a selective response to diseases without causing damage to the crop’s leaf.

3) Permeabilizer: Reacts with the sodium and calcium ions of the cell membrane of fungi, destabilizing and puncturing it, leaving points of entry for the fungicide.


  • Helps to prolong residual activity of fungicides, hence, increasing its percentage of control.
  • Provides superior fungicide spray coverage and deposition.
  • Assists the fungicide spray deposit to adhere or stick to the leaf surface and slow chemical residue loss.
  • Helps prevent dew formation and promotes faster drying of the leaf surface following rainfall or irrigation.
  • Improves foliar absorption and stomatal entry of fungicides.
  • Increases and potentiates the efficacy of contact, translaminar and systemic fungicides.
  • Accelerates the speed of droplet spray penetration on the leaves, enhancing performance on treated surfaces.
  • Reduces fungicides spray evaporation, hence increasing efficacy and control.
  • Increases fungicides permeabilization, which accelerates its action and allows the possibility of reducing fungicide rates use.
  • The majority of its components are of organic origin. It is not a pesticide and has no PHI restrictions hence it can be applied up to harvest date.
