If, like I, you don't own a grill, and the plant is (or is very nearly) dead, put the pulled-up parts into a plastic bag and tie it off. Then throw the plastic bag into the trash.
If the only thing ailing the squash (fingers crossed for you) is Powdery Mildew, it's possible that you could fight back either with the milk solution (I've recently posted detailed instrux on making it) or the baking-soda solution (someone else--I can't remember who; sorry!--recently posted instrux for making that one). A Search will find the instructions for you.
In either case, place the solution into a spray bottle and get the plant's leaves wet on top and bottom. If you're in a humid location--Florida qualifies!--it's best to do this spraying early in the morning so that the leaves aren't wet for hours and hours, which compounds the problem. The milk and baking soda solutions change the fungal colonies on the leaves so that they're hostile to PM.
But, like gumbo says, if the enemy is Squash Vine Borers, the plants are very likely done. So sorry. Plastic-bag time.
