- Spray pattern visibility: Choose markers that clearly visualize coverage to prevent under- or over-application. Concentrated formulas may require less product per gallon, offering cost efficiency.
- Water-based compatibility: Ensure the dye works with water-based solutions and is not designed for oil-based products. This affects performance with common herbicides and fertilizers.

- Fade time and safety: Consider how quickly the dye fades after rainfall or sun exposure. Safety around people, pets, and landscapes is important for home use.
- Ease of use: Simple mixing instructions and compatibility with existing sprayers save time and minimize cleanup.
- Visible color options: Different colors (blue, green) help distinguish multiple treatments or zones without confusion.
- Maintenance benefits: Some markers can reveal clogged nozzles or sprayer issues, contributing to longer equipment life and more accurate applications.
