It depends on what caused the dead patches. Could be shade, could be overwatering, could be dog urine.
Give us more details.
Norma, since burmuda grass is so hard to kill it could also be lack of water in those places.

Thanks for the answers, but I'm still hoping for more ideas.
Can you post pix?
one day new brumuda sod green . next day brown patches in spots all over
Maybe it is grubs as they can kill grass. I'm not sure if you have them where you are in Georgia. Google grub worms and you may find a lot of info such as if they are in your area and maybe will
have pictures of lawns with grub infection.
