Mold on My Cucurbits!

What you're experiencing is common on summer squash, less common on other
cucurbits (cucumbers, pumpkins, w. squash, melons, etc.). It's called
Choanephora Wet Rot. It likes soft fruit, just developing, especially if
it's touching soil and conditions are wet. If pollination is poor it can be
bad too. Using a fluffy mulch like straw, that provides good drainage helps
because it keeps the fruit elevated from the soil and dry. Clipping them off
and removing them will probably help later fruit avoid infection. Squash
produce so many fruit normally that losses from this disease are not usually
bad unless conditions remain good for the organism for a while.
