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.

powdery white mildew, I have to battle it every year. believe it or not if you get it early you can use milk, 1 or 2 parts milk to 8 or nine parts water. this is the organic ways to do it, the problems is you have to apply it after every rain.

the other way and it looks like you might have to do it is liquid copper, it will kill that powdery mildew, if you dont get it off it will kill the plant
