- 2. It's been a week since the last rain fell in the Quincy area, some have gone a bit longer. As much as I hate to say this, before the week is out, we'll probably be wanting a rain. The soil is extremely dense and very little oxygen is available. You begin to notice the soil cracking soon, which can be beneficial to allow oxygen to reach root systems. But the root system of most plants is extremely shallow, and we'll need more moisture in the upper portion of the soil horizon to support continued plant growth. Check those plants under plastic for the need to irrigate.
- Dr. Mohammad Babadoost, U of I Plant Pathologist issued a notice late last week concerning Downy Mildew on cucurbits. This can be a very devastating disease if it hits in your area. You'll need to be scouting for powdery mildew as well, as I've seen powdery mildew with some frequency of late. See the attached document from Dr. Babadoost on downy mildew.
