What is a Knapsack Sprayer?
A knapsack is a type of sprayer that disperses liquid through a hand-held nozzle that is attached to a pressurised reservoir carried on the operators back. Knapsack sprayers can be used to apply liquids such as fertilisers, herbicides and fungicides for example and is suited to spot treating areas.
Method:
- Assemble your sprayer (if new) following the manufactures instructions.
- Ensure you are fully prepared with the appropriate PPE (Personal Protective Equipment) including rubber boots, coveralls, gloves and a face shield.
- Ensure the sprayer is calibrated to the required dosage – see our guide on How To Calibrate a Sprayer.
- Fill the spray tank with the required amount of water, we recommend always reading and following the manufacturers label and instructions before use and using the rate suggested.
- Measure the chemical needed in a mixing jug in a safe environment. If the chemical container is new and is sealed with a foil, simply turn the cap upside down, press onto the foil seal and twist to remove.
- Add chemical into the sprayer with the water. We recommend not mixing more than what is needed.
- Triple rinse the measuring jug.
- Agitate the sprayer to make sure the liquid is fully mixed.
- Now you are ready to spray. Put the sprayer on your back and adjust until comfy.
PPE Personal Protective Equipment must always be worn when using a knapsack sprayer. This includes Overalls, Rubber Boots, Chemical Resistant Gloves & a Face Shield.
