Sample questions
If using SonarSRP for greenhouse or nursery plant irrigation, what condition must be met regarding water intake?
- Water intake must be verified to be below 1 ppb or 5 ppb depending on plant type
- Water intake must be verified to be below 90 ppb
- Water must be tidal saltwater
- Water must be at least 2 feet deep
Show answer
Do not use in greenhouse or nursery plant irrigation unless water intake has been verified to be below 1 ppb or 5 ppb depending on plant type.🔗 Source
What is the maximum total annual application rate for SonarSRP when used in lakes and reservoirs?
Show answer
The label states a maximum total application rate of 150 ppb in lakes/reservoirs per annual growth cycle.🔗 Source
Which condition could potentially reduce the effectiveness of the herbicide application?
- Increasing water depth to over 2 feet
- Applying during plant growth stages
- Rapid water movement or heavy rainfall
- Using it in freshwater reservoirs
Show answer
Rapid water movement or heavy rainfall can dilute product and reduce effectiveness.🔗 Source
When applying SonarSRP to ponds, canals, or rivers, what is the applicable application rate range?
- 16 to 150 ppb
- 1 to 5 ppb
- 45 to 90 ppb
- 7 to 10 ppb
Show answer
The label provides application rates of 45 to 90 ppb (ponds/canals/rivers).🔗 Source
Approximately how long after application do results typically appear?
- 1 to 2 days
- 45 to 90 days
- 7 to 10 days
- 16 to 150 days
Show answer
Apply according to plant growth stages; results appear in 7 to 10 days.🔗 Source
In which of the following environments is the use of SonarSRP restricted?
- Potable water sources
- Irrigation canals
- Tidal saltwater
- Fresh water rivers
Show answer
The label explicitly states: 'Do not use in tidal saltwater.'🔗 Source
According to the product description, how does the herbicide enter the target plants?
- Through the leaves only
- Through plant shoots and hydrosoil by the roots
- Through the stems and flowers
- Through the leaves and roots only
Show answer
The product is absorbed by plant shoots and hydrosoil by the roots.🔗 Source
What is the minimum water depth required for application, except under specific FIFRA Section 24(c) registrations?
- 1 foot
- 2 feet
- 5 feet
- 10 feet
Show answer
Do not use in waters less than 2 feet deep (except under specific FIFRA Section 24(c) registrations).🔗 Source
