How do I mix my pesticide and load my knapsack sprayer?
Review the advice below on how and where to mix your product, and how to load your product safely. See how to triple rinse emptied pesticide packs and how to avoid unwanted pesticide spills.
Before you start
Before you mix your pesticide product, make sure that you:
- are fit to spray
- have advised your neighbors where and when you plan to spray
- have checked and calibrated your knapsack sprayer
- are spraying at the right time to control the pest and that the weather conditions are right for spraying
- are wearing the right personal protective equipment (PPE) for mixing this product
- know the total amount of pesticide product and water that you will need
- know how much pesticide and water to load into each full knapsack sprayer and any part knapsack sprayer load. The spray mix calculator will help.
Check the scale on your tank
Look at the intervals to see which units are used (e.g liters of spray mix). The tank gauge on better knapsack sprayers will leave a 10% gap between the top of the gauge and the tank lid.
Have your spill kit ready to use
Use a spill kit to clean up pesticide spills and drips when they happen. Whether you buy or make a spill kit, your spill kit must cope with the worst spill that can happen with the pesticide volumes under your care.
Your spill kit must contain at least:
- sand, sawdust, soil, clay, cat litter or vermiculite to absorb pesticide spills
- shovel, broom and dustpan
- strong bag for waste e.g. polluted sawdust or single use personal protective equipment
- label and pen
- strong plastic leak-proof drum or box able to contain the largest pesticide pack you have in your store
- emergency telephone numbers.
