- A water flow rate monitoring
- A FaSTest
- An environmental safeguard assessment
- A target vegetation analysis
Show answer
The text states: 'Always perform a FaSTest before applying near potable water intakes to ensure concentration limits are not exceeded.'🔗 Source
What is the concentration of the active ingredient trifluralin-methyl in Sonar H4C?
- 0.027 lbs active ingredient per pound of product
- 150 ppb per annual growth cycle
- 0.15 lbs active ingredient per pound of product
- 150 ppb per application site
Show answer
The text states: 'The active ingredient is trifluralin (as trifluralin-methyl), which is present at a concentration of 0.027 lbs active ingredient per pound of product.'🔗 Source
Which of the following is a specific restriction regarding non-target organisms when using Sonar H4C?
- Do not use if fish are present in the water body.
- Do not use in areas where non-target organisms (fish, etc.) are at risk without following environmental safeguards.
- Do not use in rivers if fish are being managed.
- Do not use if water flow exceeds 150 ppb.
Show answer
The text states: 'Do not use in areas where non-target organisms (fish, etc.) are at risk without following environmental safeguards.'🔗 Source
In what environments is Sonar H4C effective for managing plant growth?
- Only in still water environments
- Only in moving water such as canals and rivers
