If one isn't worried about chemical applications, the following 2 articles have some suggestions, although it may end up with expensive multi-year chemical spraying projects. http://archive.lib.msu.edu/tic/golfd/article/2008mar80.pdf The best treatment was fenoxaprop-P plus triclopyr plus mesotrione. This combination reduced bermudagrass cover from 71 percent when the study started to 2 percent when evaluated mid-summer in the next season. The majority of the plots treated with this combination were completely free of bermudagrass. No previous selective bermudagrass control program has reduced bermudagrass populations this much in one growing season. Although this strategy does not affect bermudagrass in summer for about two months, we speculate that spring applications provide enough initial suppression to limit active growth through most of the summer, and then fall applications completely deplete energy reserves in rhizomes and stolons. Bermudagrass then succumbs to the combination of herbicide effects and winter kill. https://utextension.tennessee.edu/sullivan/Documents/Controlling% 20bermudagrass%20and%20turf%20grass.pdf Fluazifop (Fusilade II) and fenoxaprop (Acclaim Extra) are two effective products for bermudagrass control in tall fescue and zoysiagrass. When applied alone for selective bermudagrass control in established turfgrass, fluazifop, and fenoxaprop can be injurious to tall fescue and zoysiagrass. Triclopyr (Turflon Ester) safens the use of fluazifop and fenoxaprop while improving or providing similar bermudagrass control compared to the same products applied alone.
