    Hi Susan,


    Go to Google and look up "companion plants", it will tell you what to plant with your squash that will naturally repel pests. We do this all the time and have great results without any pesticides.

      This is not from a pest. It is called powdery mildew and will spread rapidly. They make a specific spray for it but you must coat the entire plant under the leaves etc. Pick off the bad leaves and treat AS SOON AS YOU SEE IT APPEAR. The longer it is on the plant the quicker it will kill the vines. You can also use milk. Yes plain old milk in a spray bottle. if caught early it will really help.

    YOU HAVE POWDERY MILDEW. You could try spraying with a bit of baking soda in water. Leave for a few minutes and then rinse again. Do not do this in the hot sun.

    Hi Susan Combine one tablespoon baking soda and one-half teaspoon of liquid, non-detergent soap with one gallon of water, and spray the mixture liberally on the plants. Mouthwash. The mouthwash you may use on a daily basis for killing the germs in your mouth can also be effective at killing powdery mildew spores.
