Eradicating guinea grass in bermuda.

[whitewing]

I'll be visiting a client in the morning to look at his bermuda and am pretty sure what I'll find....lots of guinea grass and other bunch-grasses in the bermuda. I looked at this place last year while delivering bales to them (a horse riding, tourist-type place) and found plenty of guinea grass and other unwanted visitors invading their bermuda.

I've had the same stuff at my place but keep it under control with regular harvesting of my bermuda.

Any suggestions?

I recommended to them last year that they get aggressive with it, like mowing everything and then spraying the guinea grass bases with glyphosan. Since the owners have told me they didn't produce a single commercial bale of bermuda last year, I doubt they were very aggressive with the bunch grass.

Thanks in advance for your responses.
