Potassiumiodide + potassiumthiocyanate


ENZICUR is a natural anti-microbial system for control of powdery mildew (Erysiphe spp, Leveillula taurica, Oidium spp, Spaerotheca spp) in various crops. The product is based on naturally occurring salts (potassiumiodide and potassiumthiocyanate), enzymes (lacto-peroxidase) and substrates.


The effect is based on the formation of reactive oxygen ions, that inactivates micro organisms by oxidation. ENZICUR has a curative effect on powdery mildew, and kills both spores and mycelium on the treated surface. It works only when dissolved. Activity stops when spray solution has dried up.


ENZICUR is safe for humans and environment, development of resistance is not possible


Unit of packaging

  • 1 bag with 3 compartments containing powders, total 300 resp. 1,500 gram
  • 1 bottle with additive based on emulsifiable vegetable oil, resp. 500 and 2,500 ml.

This quantity is sufficient to prepare 200 resp. 1,000 liter spray solution.



  • Apply ENZICUR when first signs of the fungal disease are observed
  • Use regular high volume spray equipment
  • Ensure good leaf coverage, specially target the parts where fungal disease occurs
  • Repeat treatment after 5-7 days if necessary


Preparation of solution

  • Fill the spraytank up to 75% of the required amount of spray solution using water with pH between 5.5 and 6.5
  • Empty the entire content of the bag slowly while stirring the spray solution. Make sure all 3 compartments of the bag are totally empty
  • Never dissolve the powders in a small amount of water since this inactivates the system
  • First dissolve the powders thoroughly in the spraytank, then add the emulsifiable vegetable oil based adjuvant
  • Use the entire content of both powders and additive at once
  • Flush bottle and stir spray solution
  • Add the final 25% of water to the spray solution, then stir once more
  • Apply the spray solution onto the crop
  • Use the solution within 8 hours after preparation

  • Storability: see package for expiry date
  • Keep dry at temperature lower than 10°C, prevent freezing
  • Closed in original packagaging



  • Use at least 1,000 l/ha spray solution for low crops and 2,000 l/ha in high crops for sufficient wetting of the crop


Empty packaging is normal (not chemical) waste, if flushed properly

Visual effect

the fungus dies approximately 24 hours after application of ENZICUR, then becomes greyish. Powdery mildew can even dissappear completely, just leaving a light green spot on the place where the fungus has attacked the leaf.
