Drone Application for Bahiagrass Control

Bahiagrass Control

Bahiagrass (Paspalum notatum) is a tough perennial that invades and out-competes improved forage and hay stands.

How to identify it

Bahiagrass is easiest to name by its seed head: a tall, bare stalk splitting into two (sometimes three) slender, spreading branches in a distinctive V or Y, each lined with rows of seed along one side. Below it sits a tough, low mat of coarse runners that shrugs off close grazing.

Why it’s a problem

Where it isn't wanted, bahiagrass spreads by rhizome and seed, tolerates close grazing, and crowds out higher-quality improved forage, dragging down hay value and pasture productivity over time.

When a drone is the right tool (vs. a ground rig)

Coverage lands evenly across the whole field, soft and wet spots included, which keeps the pass tied to the grass's growth stage in a week when a truck would still be waiting for the field to dry.

Best time to treat

Treat while the grass is actively growing and green, generally late spring through summer, so a systemic herbicide can move through the plant to the roots. Dormant or drought-stressed turf barely takes it up, which is why the growth stage sets the date. Restoring the field to better forage is part of the longer plan.

Treatment cost

Field size is the main driver, and the growth stage we catch the grass at is the other. Tell us about the pasture or hay field and we'll quote it.

A note on results: a treatment reduces an infestation, and no application can guarantee a percent kill. We scope every job to the site in front of us and tell you what a pass is likely to do.
