ISU Plant & Insect Diagnostic Clinic

Have you seen any problems in your landscape or garden so far this spring? Not sure what's going on? Reach out to us! Feel free to comment below or email us at [email protected] with photos and information, or start at your local county Extension & Outreach office! Plant problem diagnostics are never certain with photos alone, so we may ask for a physical sample submission (fees apply). Don't get caught with your plants down!

This year, the PIDC had the pleasure of having Natalia as an intern, who came to us all the way from Costa Rica! Thank you for all of your help in the clinic. We will miss you!

The PIDC will be temporarily closed November 6-8 next week. We will be slow to respond to emails but will get back to you as quickly as possible. Thank you for your understanding.

Now's the time to scout for squash bugs! 🧑‍🌾

Handpick and discard egg clusters and nymphs as they appear. Use garden insecticides such as Sevin, permethrin or insecticidal soap according to label directions. Sprays are generally more effective than dusts, but must be reapplied frequently. Avoid spraying plants in bloom. If spraying during bloom is necessary, spray at night after honey bees have quit foraging for the day. Remove crop residues in the fall to reduce the number of squash bugs that survive the winter.
