Boxwood Lovers: Beware of the Blight

Although boxwoods (Buxus sp.) are not native to the U.S., their versatility has made them one of the most popular shrubs for edging, hedges, and topiaries in classic and modern landscapes. We at Iowa Plant and Insect Diagnostic Clinic see few foliar diseases of boxwood, but most commonly we receive photos and samples with symptoms of winter injury.

Mycology for Kids- Part 1

During mid-April, our Diagnostician Lina was interviewed by a young gentleman for his school project. He wanted to learn about Mushrooms, mushroom identification, Mycology and meet with the diagnostician to understand what she does at the Plant and Insect Diagnostic Clinic 

This video is part of a series of videos from that interview. We discussed how do we identify mushroom in the clinic, and how the clinic helps train Iowa citizens to recognize true morel mushrooms, avoid false morels and be certified to sell true morel in the state of Iowa legally.

Complete Nematode (Corn/Turf) Sample Submission

The PIDC provides identification and counts of the nematodes that feed on grasses (corn and turfgrass).  We provide information about the nematode species, thresholds, and management information.  We can also identify nematodes on other plants, but please contact us for specific sampling instructions.  If you are looking for information on submitting SCN (soybean cyst nematodes) samples please click here.   

Digital Photography (Plant problems)

Digital images of plant problems symptoms and mushrooms (causing rots on woody plants) can be very useful for diagnosis and identification. Digital pictures are free and easy to submit. We do not provide diagnosis or identification on an image only because it is not feasible in most cases to make even a good guess, but we will accept images in order to assist in determining what type of sample is most appropriate. Here are tips to help send better pictures.
