Pumpkins are doing well. I gave my pumpkins a side dress application of nitrogen the first week of August and they have really taken off we have fruit starting to size nicely. I have not seen any signs of powdery mildew yet but have started spraying preventative fungicides, especially given the...

If you work with specialty crops or have experience with two-spotted spider mites, please complete a survey from Purdue University designed to determine the limit of detection of spider mite damage. All responses...

The Farmers Market Food Safety Guide was developed to provide standards, guidelines and consistent information to Illinois vendors and market managers to provide fresh, safe and quality food to...
