Pat,
Perhaps the best and safest product for clover control (zoysia or any other grass I am familiar with) is MCPP. It is an old product. Most 3-way mixes have some MCPP in them. I have not seen any injury spraying 3-way products on Meyer zoysia any time of year. That does not mean it can't happen and perhaps someone has seen damage from spraying this time of year. 2,4-D alone is not very good for clover control but MCPP alone is very good. However you may have some other winter broadleaf weed that MCPP is weak on, therefore a 3-way mix is probably your best option.
