Gordons Ornamec 170 Grass Herbicide is actually labeled as safe to use on zoysia grass as directed, so we do not recommend using this to try and kill zoysia in your jasmine. Unfortunately, there is not a grass killer herbicide that is labeled to control zoysia in groundcovers. You may hand pull the grass or consider spot treating it carefully using a non-selective herbicide such as Roundup QuickPRO.
