Fungus, spider mites, probably stem borers too. What zone are you in and when did you plant it? Squash seem to die very quickly around here. I've given up on them entirely.

Interesting. Thanks for the info. I live just outside of Orlando, Fl. Planted them in Sept i think

cmrauth, your plants to me look like they are ready to pull out. In my area, I had zucchini plants and they are already out after giving me plenty of squash, one was more productive than the other varieties and one was hit with the hurricanes and blown out.

Soon you can start new plants for the season, make sure that everything is cleaned and if possible start them in another place and if not put more soil.

In my garden, some of the ones that I grow

Great info all thanks. I didn't get a single fruit from the plant, they all turned to mush. I just cut a few remaining ones open and identified at least one problem as picture below

It looks like insect damage, maybe borers? In the future you can maybe use row covers when growing. In my organic garden I used Dipel dust only once in the season and did not get any borers or pickle worms.
