Re: planting preparation

It can be used to clean up buffalograss in lawns but I don't think it will
address your specific problems. Buffalograss, though on the label, seems to
be particularly rate sensitive to Plateau. However, I have used a 3 ounce
rate for establishing Bison buffalograss with great results. The problem is
that it takes at least 10 to 12 ounces of Plateau to be effective on fescue.
I don't know about dandelions. If using Plateau on buffalograss use
absolutely no more than 4 ounces per acre, using accurate application
equipment. Apply it when the grass is not under any type of stress from
moisture or temperature.

2,4-D can be used on buffalograss with the same stress precautions listed
above. Don't apply it when air temperatures are above 80.

The good news about Plateau or 2,4-D on established buffalograss is that if
you get too much on and damage or top kill the plants, as long as it wasn't
extremely too much, the plants will come back though you lawn will be ugly
for a while.

Regarding fescue in buffalograss lawns, I'd use Roundup in the dormant
season.

Stock Seed Farms in Murdock, NE is a good resource for information regarding
managing buffalograss lawns. Their number is 402-867-3771. They also have a
web site but the address escapes me now.
