General Instructions: WHACK 900 WG Fungicide

Overview: WHACK 900 WG is a protectant fungicide designed for the control of various diseases in fruits and vegetables. Achieving a good leaf cover is crucial for effective disease control, especially before a widespread disease outbreak occurs.

Application:

Dilute Spraying:

• Use a sprayer designed for high water volume applications up to the point of run-off.
• Set up and operate the sprayer for even coverage throughout the crop canopy, avoiding excessive run-off.
• Determine the required water volume by conducting tests or consulting industry guidelines.
• Add the specified product amount for each 1000L of water according to the Directions for Use. Spray to the point of run-off.
• Adjust the dilute spray volume and sprayer setup as the crop grows.

Concentrate Spraying:

• Use a sprayer designed for concentrate spraying (e.g., low volume air blast) matched to the crop.
• Operate the sprayer for even coverage throughout the crop canopy using the chosen water volume.
• Determine the appropriate dilute spray volume (refer to dilute spraying) for the crop canopy to calculate the concentrate mixing rate.
• Calculate the concentrate mixing rate based on the concentration factor.
• Adjust spray volume, product amount per 100L of water, and sprayer setup as the crop grows.
• Consult industry guidelines and undergo competency training for concentrate spraying.

Mixing:

• Half fill the spray vat and, with the agitation system running, add the required amount of the product.
• Top up with water to the required volume, ensuring continuous agitation.
• Keep the product in suspension at all times. Thoroughly re-agitate prepared spray mixes before use.

Application Rates per Hectare:

• Low Volume: 200L or more
• High Volume: 500L or more
• Aerial Application: 20L or more
• Mister: 75-255L

Compatibility:

• WHACK 900 WG is compatible with wettable powder and flowable formulations of most commonly used fungicides, insecticides, and miticides.
• Do not combine with other chemicals, especially oil-based emulsifiable or flowable pesticides.
• Do not mix with spraying oils or spray onto crops sprayed with oil for at least 10 days after the last spray.
• The volume of water applied should increase as plants grow to maintain adequate cover.

Resistance Warning: FUNGICIDE RESISTANCE WARNING

• WHACK® 900 WG belongs to the multi-site activity group of fungicides and is a Group M5 Fungicide.
• Some naturally occurring fungi resistant to WHACK 900 WG and other Group M5 Fungicides may exist.
• Continuous use may lead to resistant fungi dominating the population, reducing efficacy and causing potential yield loss.
• Detection of resistant fungi before use is challenging, and Imtrade Australia Pty Ltd assumes no liability for losses resulting from the failure of WHACK® 900 WG to control resistant fungi.
