When tank mixing Sonar Genesis with other aquatic herbicides or algicides, what instruction must the applicator follow?
- Always use the most dilute concentration
- Only mix with products containing Fluridone
- Follow the most restrictive directions
- Do not tank mix with any other aquatic herbicides
Show answer
The label states: 'Can be tank mixed with other aquatic herbicides/algicides; follow most restrictive directions.'🔗 Source
What is the required thickness for chemical resistant barrier laminate when used as part of the required PPE?
- At least 10 mils
- At least 14 mils
- At least 20 mils
- At least 5 mils
Show answer
The label states: 'chemical resistant barrier laminate, butyl rubber ≥ 14 mils, natural rubber ≥ 14 mils, neoprene ≥ 14 mils, nitrile rubber ≥ 14 mils, polyethylene, or polyvinyl chloride (PVC) ≥ 14 mils.'🔗 Source
If an applicator intends to use Sonar Genesis for the irrigation of greenhouse or nursery plants, what condition must be met?
- The concentration must be verified below 1 or 5 ppb
- The concentration must be exactly 90 ppb
- The plants must be submerged in a reservoir
- The water must be sourced from a drainage canal
Show answer
The label states: 'Do not use for irrigation of greenhouse/nursery plants unless concentration is verified below 1 or 5 ppb.'🔗 Source
What is the specified application restriction regarding potable water intakes?
- Do not apply within 1/2 mile of potable water intakes
- Do not apply within 1/4 mile unless specific concentration requirements are met
- Do not apply to any potable water sources
- Do not apply within 100 feet of potable water intakes
Show answer
The label states: 'Do not apply to potable water intakes within 1/4 mile unless specific concentration requirements are met.'🔗 Source
When determining the correct application rate for Sonar Genesis, which factors must be considered according to the product label?
- Water temperature, sunlight exposure, and water movement
- Target plant species and water depth
- The size of the pond and the volume of water
- Current wind speed and the salinity of the water
Show answer
The label states: 'it is critical to determine the target plant species and water depth to select the correct application rate'🔗 Source
What is the specific mechanism of action by which the active ingredient Fluridone works to manage aquatic vegetation?
- It inhibits the formation of carotene, leading to chlorophyll degradation
- It prevents the absorption of sunlight by the plant's leaves
- It destroys the cell walls of submerged plants directly
- It interferes with the plant's ability to absorb nutrients from the sediment
Show answer
The label states: 'It works by inhibiting the formation of carotene in plants, which leads to the degradation of chlorophyll.'🔗 Source
