There is no post-application holding restriction against use of treated water for drinking or recreational purposes (e.g. swimming, fishing).
Treated water may be used for irrigation purposes on truf and landscape ornamental as outlined in the section on the label Irrigation Restrictions and application table.
When making solution, use dilution water having a pH of 5 to 7. Apply in early morning to actively growing weeds and early in the season. This product is a contact herbicide that quickly degrades in the water column. This product is repidly absorbed by target plants but also breaks down quickly in water with a pH greater than 8.5. The pH of water surrounding mats of submesed vegetation can exceed 8.5 by early to mid-day, due to photosynthetic processes. Application of this porduct under these conditions may provide only partial weed control, and regrowth is likely. Clean spray equipment according to instructions on label.
This product can be toxic to non-target plants and aquatic invertebrates. Do not apply directly to treated, finished drinking water reservoirs or drinking water receptacles when the water is intended for human consumption. Drift and runoff may be hazardous to non-target plants and aquatic organisms in water adjacent to treated areas. Do not apply where runoff is likely to occur. Do not apply when weather conditions favor drift from treated areas. Do not contaminate water when disposing of equipment washwaters or rinsate.
Treatment of aquatic weeds and algae can result in oxgen loss can cause fish suffocation. Therefore, to minimize this hazard, treat 1/3 to 1/2 of the water area in a single operation and wait for atleast 10 to 14 days between treatments. Begin treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas. Consult with State agency with primary responsibility for regulating pesticides before applying to public waters to determine if a permit is needed.
