Dilute Spraying:

  • Use a sprayer designed to apply high volumes of water up to the point of run-off and matched to the crop being sprayed.

  • Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of run-off. Avoid excessive run-off.

  • The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from industry guidelines or expert advice.

  • Add the amount of product specified in the Directions for Use table for each 100L of water. Spray to the point of run-off.

  • The required dilute spray volume will change and the sprayer set up and operation may also need to be changed, as the crop grows.

Concentrate spraying:

  • Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of run-off) and matched to the crop being sprayed.

  • Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.

  • Determine an appropriate dilute spray volume (see dilute spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate.

  • The mixing rate for concentrate spraying can then be calculated in the following way:

    • i) Dilute spray volume as determined above: For example 1500L/ha

    • ii) Your chosen concentrate spray volume: For example 500L/ha

    • iii) The concentration factor in this example is: 3 x (i.e. 1500L ÷ 500L = 3)

    • iv) If the dilute label rate is 10mL/100L, then the concentrate rate becomes 3 x 10, that is 30mL/100L of concentrate spray.

  • The chosen spray volume, amount of product per 100L of water, and the sprayer set up and operation may need to be changed as the crop grows.

  • For further information on concentrate spraying, users are advised to consult the relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

Half fill spray vat and with agitation system running, add the required amount of product. Top up with water to the required volume. The product must be kept in suspension at all times by continuous agitation. Where prepared spray mixes have been allowed to stand, thoroughly re-agitate before using.


  • Low Volume: 200 or more litres per hectare.

  • High Volume: 500 or more litres per hectare.

  • Aerial Application: 20 litres or more per hectare.

  • Mister: 75 - 255 litres per hectare.
    The volume of water applied should increase as the plants grow in size to maintain adequate cover.

This product is compatible with wettable powder and flowable formulations of most commonly used fungicides, insecticides and miticides. Unless experience in your area has shown other combinations to be physically compatible and non-injurious to your crop do not combine with other chemicals, especially oil based emulsifiable or flowable pesticides. This product should not be mixed with spraying oils or sprayed onto crops that have been sprayed with oil for at least 10 days after the last spray.
Wetting Agents: The addition of surfactants does not improve this product’s efficiency and under some conditions may cause plant injury.

Smart Chlorothalonil 900 WG Fungicide is a member of the multi-site activity group of fungicides. For fungicide resistance management, the product is a Group M5 fungicide. Some naturally occurring individual fungi resistant to the product and other Group M5 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungal population if these fungicides are used repeatedly. These resistant fungi will not be controlled by this product or other Group M5 fungicides, thus resulting in a reduction in efficacy and possible yield loss. Since the occurrence of resistant fungi is difficult to detect prior to use, Crop Smart Pty Ltd accepts no liability for any losses that may result from the failure of this product to control resistant fungi.
