What this is based on

Each point below names the source it comes from and what that source actually says.

Pesticide certification is the hard entry gate

EPA's certification-and-training material sets the framework for certified applicators, and states administer the commercial applicator categories and exams. For lawn treatment, herbicides, insecticides, fungicides, weed-and-feed, and other pesticide products generally put the operator in the pesticide-applicator lane rather than ordinary yard work.

The economics are recurring-program economics

The owner-income and lawn-care margin sources support the idea that treatment programs can carry strong gross margins, but they are business-guide and trade-source numbers rather than public owner earnings. The page haircuts the owner band for renewals, callbacks, product cost, route density, insurance, and compliance.

Sources

Fertilizer-only rules can still matter

Pesticide certification is the clearest gate, but fertilizer application, nutrient runoff, product labels, and local water-quality rules can add limits. The state category has to match the actual products and target sites.

What’s not known
Treatment-only owner take-home

No clean public dataset gives owner take-home for fertilizer and treatment-only routes separate from mowing, landscaping, tree care, and franchises. The page uses a directional owner band.

Exact local category and fertilizer rules

State pesticide categories and fertilizer or runoff rules have to be checked locally. The page treats certification as the hard class of requirement, not a single national form.
