Zucchini Stem rot - I believe Squash vine borer is responsible

My zucchini have been a great source of greens over the summer but i am having a problem with them. Their base is rotting and when I was picking dead leaves off of one of the plants the whole stem split in half. From waht I can tell this is due to the extensive rain and humidity of the recent weeks and it really seems like the problem is the Squash vine borer so I don't need a diagnosis I just wonder if anyone has a solution or if my zucchinis are fucked.
