Q.Removing insects causing blight
I have had blight on winter squash (particularly), rutabaga and tomatoes (I think). Carrots and kale escaped the curse just fine. We had an early rainy, cool season. I likely overwatered, too. Question is: my garden is only 8’x12′, and there is no room to effectively rotate my crops. How do I get rid of the insects that bring the blight? (For coming year.)
Before growing anything in that area, I would recommend solarizing the soil in the planting bed. This should help kill off any leftover bacteria as well as any insects that may be overwintering in the soil.

During the growing season, you can also treat plants with neem oil, which is safe to use and effective against many types of insect pests. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
