Powdery Mildew

Yuck, powdery mildew has devastated our squash and pumpkin efforts. This common fungus first started in our cucumber patch in late July, we didn't catch it early enough and then the air born spores migrated their way to our zucchini plants. We still were able to harvest a substantial amount of zucchinis but it definitely cut our season short. By mid August the powdery mildew ravaged our blue ballet squash and small sugar pumpkin plants (part of our Iroquois Three Sisters Garden). The fruit of the squash and pumpkin plants are still hanging on but we are not sure for how much longer. We were hoping to harvest the squash in mid October but we might have to pick it sooner in order to save it. We will try to "keep" it for as long as we can so the second grade can use it in their Harvest celebration in November.

We treated the effected leaves by spraying them with a mixture of baking soda(natural fungicide) and water. This seemed to slow down the spread but next year if this happens we will start our treatment earlier and more aggressively. In the meantime we will look into ways to prevent this from happening next year.
