Sample questions
According to the label, when should CaptainXTR be applied to filamentous algae?
- During the dormant winter season
- Only when water is stagnant
- Early in the season or when regrowth begins
- Immediately after a high-density bloom occurs
Show answer
The timing/weather section states to apply for filamentous algae early in the season or when regrowth begins.🔗 Source
Which of the following is a required piece of Personal Protective Equipment (PPE) for handling CaptainXTR?

- Green and blue-green (cyanobacteria) algae
- Invasive aquatic insects
- Floating lily pads only
- Surface-dwelling snails
Show answer
The label states CaptainXTR is used to control a broad range of green and blue-green (cyanobacteria) algae.🔗 Source
What is the maximum allowable application rate for CaptainXTR in a single application?
- 0.2 ppm copper
- 1.0 ppm copper
- 2.0 ppm copper
- 9.1 ppm copper
Show answer
The restrictions state: 'Do not exceed 1.0 ppm copper in any single application.'🔗 Source
When treating flowing water, which method is suggested for application?
- Manual hand-spraying
- Aerial crop dusting
- Drip or metering pump systems
- Submerged injection rods
Show answer
The label states that for flowing water, the product may be applied via drip or metering pump systems.🔗 Source
CaptainXTR can be used to control submerged weed species, provided they meet which criteria?
- They must be floating species
- They must be susceptible to copper
- They must be in still water only
- They must be non-toxic
Show answer
The application notes state that submerged weed species must be susceptible to copper.🔗 Source
Under which condition does the toxicity of CaptainXTR to non-target aquatic organisms increase?
- High density cyanobacteria blooms
- Low pH or low DOC waters
- High flow rate canals
- High temperature reservoirs
Show answer
The restrictions note that in certain water conditions, such as low pH or low DOC, toxicity to non-target aquatic organisms increases.🔗 Source
What precaution must be taken regarding cyanobacteria blooms to prevent public health risks?
- Always apply at the highest possible rate
- Avoid application to high density blooms to prevent toxin release
- Only apply during high wind conditions
- Mix with additional chemicals to neutralize toxins
Show answer
The label warns to avoid application to high density cyanobacteria blooms to prevent toxin release and public health risks.🔗 Source
