Answer: Wire grass is also called devil grass but it is botanically Cynodon dactylon, and grown as bermuda grass - an oft used turfgrass in the southern states. If bermudagrass seeds germinate in areas around ornamental plantings, the seedlings can be controlled with shallow cultivation, hoeing, or a thin layer of mulch.
Herbicides such as Round Up (glyphosate) will kill the plants but not the seeds they leave behind. And, Round Up is a contact vegetation killer so anything it touches will also be damaged. You might have some success by using a pre-emergent such as the corn gluten based product called Concern. Pre emergence products should be applied in February, prior to germination of bermuda grass seeds.
