There are chemicals with long names that suppress plant growth but I imagine they suppress all plants not just grass. Green-keepers put it where there is only grass growing.
Gardening is a relentless process of removing what you don't want and encouraging that which you do want. The yellow rattle would die if you got rid of all the grass.
Raining again so won't be removing that which I don't want today
