Safety First

AQ200 is an Aquatic Herbicide therefore it is important to wear the correct PPE when handling and applying.
PPE: Safety glasses, gloves, mask, non-absorbent clothing, waterproof boots

10-Day Withholding Period

After safely applying AQ200 there is a 10-day withholding period meaning you cannot use the water for any purpose for 10 days: no irrigating, no stock watering, no recreational activities for 10 days.

Will AQ200 affect fish and wildlife?

The risks involved with using AQ200 are as follows:

  • Direct Spray – moderately to practically nontoxic to fish and aquatic invertebrates. There is low risk to fish in ponds being treated with AQ200. There is no risk to birds that feed on fish in the treated pond. Use the lower application rate in areas where fish are present.
  • Off-Site Drift to Non-Target Terrestrial Plants – This risk can be greatly minimised by taking care when spraying, only spraying on wind free days and only using a course droplet spray.

Nonselective contact herbicide

AQ200 is a nonselective contact herbicide for the control of aquatic weeds. This herbicide is a cell membrane disrupter that causes damage to cell membranes. AQ200 neutralises when in contact with sediment particles therefore it does not affect the roots of plants. When treating submerged weeds, ensure the water is clear and not cloudy otherwise treatment may be ineffective. If there is algae present, you may need to apply an algaecide prior to using AQ200 or use the heavier dosage rate.
