Product Overview: OzCrop Chlorothalonil 900 WG Fungicide is a protectant fungicide designed for controlling a range of diseases in fruits and vegetables. To ensure effective disease control, it must be applied before diseases occur or become established.

Application: For best results, apply before the widespread outbreak of diseases. Utilize disease warning services or past history to determine the timing of the first spray. If diseases are already present, use an eradicant product first, mixed with OzCrop Chlorothalonil 900 WG Fungicide.

Application Methods:

  • Dilute Spraying:

    • Use a sprayer designed for high water volumes up to the point of runoff.
    • Ensure even coverage throughout the crop canopy.
    • Apply sufficient water to cover the crop to the point of runoff, avoiding excessive runoff.
    • Adjust water volume and sprayer setup as the crop grows.
  • Concentrate Spraying:

    • Use a sprayer designed for concentrate spraying with water volumes less than those reaching the point of runoff.
    • Determine an appropriate dilute spray volume for the crop canopy.
    • Calculate the concentrate mixing rate based on the dilute spray volume and chosen concentrate spray volume.
    • Adjust settings as the crop grows.


  • Half-fill the spray vat and, with agitation running, add the required amount of product.
  • Top up with water to the required volume, keeping the product in suspension through continuous agitation.
  • Thoroughly re-agitate prepared spray mixes that have been allowed to stand.
