What is the maximum percentage of vegetation that can be sprayed in the zone 10-30 meters from an open body of water?

• A. 0% (no spray allowed)
• B. The regulations do not specify a maximum percentage for the zone 10-30 meters; must follow general guidelines.
• C. 50%
• D. 100%

Answer: (B)

Understanding spray near open water focuses on protection through setback distances and drift control rather than a fixed share of vegetation you’re allowed to treat. In Alberta, there isn’t a stated maximum percentage you can spray within the 10–30 metre zone from open water—the rules require you to follow the general application guidelines and the product label, plus apply drift-reducing practices and maintain the appropriate buffer. This means the correct approach is to rely on the established buffer distances and guidelines rather than a numeric percentage. The other options suggest a fixed cap, which the regulations do not specify. If in doubt, always check the product label and provincial guidelines for the exact buffer and drift-control requirements.
