Powdery Mildew on Squash

Two of my squash had definite powdery mildew. This one looks like it was just about to go into full bloom with it. I wasn't sure if it would be able to fight it off but I pulled it anyway. This was a few days ago, I checked them the remaining squash plants and they look ok so I think I got it before it spread to the rest of the plants.



I found a good answer about powdery mildew on Plant Answers:

Q. My squash leaves are covered with a white, powdery substance. The plants die rapidly.

A. This is powdery mildew. It is a fungal disease that attacks squash, killing the plants. Some varieties tolerate this disease better than others. Powdery mildew is more of a problem in the fall than in the spring. The material benomyl, or Benlate, is the most effective fungicide for the control of powdery mildew. Mildew occurs most often on old foliage of declining plants. Succession plantings of squash will provide vigorous, productive plants and allow removal of older, more susceptible plants.
