Powdery Mildew

So our squash have been looking sickly for a while, and we've finally narrowed it down to Powdery Mildew. It's a nasty little fungus that grows on the surface of rough leaves as a result of humid conditions and poor air circulation. We looked up some remedies, and decided to try a mixture of baking soda and water (one tablespoon per liter)*.

We sprayed all of the infected leaves and then let them dry in the sun. It seemed to kill the mildew on contact. If this fails us, we've also read about a milk solution that can be applied to the leaves.

*We later learned that this mixture was too strong and burned some of our leaves.
