Hmm...well, to her the verbal instruction means nothing right now. It sounds like she is convinced that the only safe place to go is the strip of fake grass.
I feel your pain. My dog was 7 months old when we got her, and refused to go to the bathroom on leash at all for several days. We don't have a backyard. It was unpleasant and stressful for everyone. But, we got past it! I think some dogs, especially females, are naturally pee-shy. And I think punishment/aversive/traditional housetraining methods compound the problem for these dogs. Not sure if you tried that sort of thing.
How long have you had her? What methods have you used to housetrain her? Did you ever punish her, yell at her, or scare her for having an accident in front of you? What happens if you take her to the strip of fake grass on a leash?
