I posted this on the squash forum but got no response so I'm asking again here.

I've got Bt in powder form. Having seen my first squash bugs and knowing that the SVBs are close behind I want to be ready.

How much powder do I mix with how much water to make the liquid to inject into the vines?

How much to I inject into said vines?

How often along each vine should I do the injection for the vines that run along the ground?
