What is the Quick Test
The Quick-test is a simple method by which plants (grasses and some broadleaf weeds) growing in your paddock can be tested for herbicide resistance. The test takes 4 weeks to complete.
How old can the plants be?
The Quick-test will work on plants from seedlings to advanced tillering as long as the plants are green and healthy.
Transplanted plants with new leaves are sprayed in a cabinet sprayer.
When can plants be sampled?
Plants can be sampled either before a herbicide application (eg. break of season) or after herbicides have been applied and weeds aren’t killed.
Sampling for Quick-Test
It is important to provide accurate details where the plants were collected from during registration.
- Collect 50 to 100 plants per paddock, aim to collect 20 plants per herbicide test.
- Collect plants suspected of being resistant if collected after a herbicide application.
- Carefully pull out plants and shake off soil from roots.
- Wrap in a couple of sheets of paper toweling.
- Too much paper towel can dry small plants out.
- Do NOT wash plants.
- Place the wrapped plants in a waterproof plastic bag eg. a sealed sandwich bag.
- Keep in fridge until ready to post.
- Mail to P. Boutsalis using Australia Post (Express Post) at the address above.
- Aim to post at the beginning of the week so plants are received within the week.
