Before you start, ensure:
- you have the right safety equipment
- the weather conditions are good, that is, a sunny day
- all pets and children are safely away from the area
- you have read and heeded all of the herbicide labels and equipment manuals
The equipment you will need is:
- hat, safety eyewear, long-sleeved shirt, long pants, gloves, covered footwear
- chemical resistant gloves, face shield, mask, impervious apron
- herbicide, knapsack and measuring containers.
Herbicide mixing
Estimate the amount of mixture you will need - be conservative. It is easier to mix up more herbicide than it is to dispose of excess mixture.
Add the required amount of water to your sprayer. Then, measure out the required amount of herbicide. (The quantities are available on the APVMA off label permit.)
Add the herbicide to the water. Seal the lid tightly and agitate the sprayer to mix it through thoroughly.
Spraying
Spray close to the target plants to a reasonable distance avoiding drifting or splashing of the herbicide, potentially killing other plants. Ensure the breeze is not blowing any spray particles onto plants you value.
Spray to cover all leaves and stems to the point of visible wetness. Be systematic to avoid spraying the same area twice.
Ensure the treated area is not disturbed for 24 hours to allow herbicide uptake.
Clean up
The best way to dispose of any herbicide is to use it up as per label instructions until the product is gone. Any left over mixture should be used up on target weeds.
Never pour the product down the sink or storm drain as it can contaminate water sources and harm aquatic life.
All equipment and empty containers should be triple rinsed to remove all traces of herbicide. Use the rinse water from containers on target weeds.
