Fan tip for Ryobi model P2800BTL rec?

Georgia zone 8b. we are taking care of our zorro zoysia, 1000 sq ft, so small yard. I"m sruggling figuring out how to appropriately spray out one gallon at the correct walking space.

So we got the Ryobi sprayer and wanted to ask about a tee jet nozzle.

Do we need an adapter? Which nozzle would do a nice fan spray?

Thank you for helping a gal out!
