You can use any Roundup product to kill the Fescue quickly and allow you to reseed with the Zoysia within 1-2 weeks usually at most. Keep in mind that zoysia seed is best put down in the spring as it thrives on warmer weather where as in the fall you normally seed with cool season grasses that thrive in the cooler temps like Fescue and bluegrass.
