No, no software on earth can "correct" backlash. Only mechanical changes to your mount can.
But PHD can reduce the effect backlash has on its ability to guide, by measureing it and anticipating it when guiding in declination. So the consequences it has for its operation is greatly reduced. PHD does this automatically, so you don't have to worry about it. Its behaving true to its name here.
You could also NOT guide the mount. Or at least not guide in declination - which is likely what most simple tracker have to do anyways, as they have no drives on that axis. Then backlash has zero consequences, is entirely irrelevant, you would never know your mount has any.
