Answer: Sounds like your plants have a bad case of powdery mildew. Older leaves on plants generally do turn yellow as they age, but it's less common on squash family plants. The humid summer we've had in the northeast has created a mold's paradise! You can try to stop the spread of the disease with Soap Sheild, a new product introduced by Gardens Alive (5100 Schenely Rd., Lawrenceburg, IN 47025, ph# 812/537-8650). And keep your fingers crossed!
It's normal for squash family plants to produce some "eager males" before the female blooms appear.
