Plant and Insect Diagnostic Clinic Update – May 23, 2018

The following are highlights and updates about sample submissions for our different services (identification or Plant problem diagnosis from fruit, vegetables, and ornamentals), and questions recently received in the Plant and Insect Diagnostic Clinic. Visit the PIDC's Facebook page for updates and more pictures. For more information on a particular disease or insect problem listed, follow the article cited.

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.  

Submitting Conifers

Needle drop/tip blight samples: collect 2-3 branches approximately 1.5-2 feet in length showing both symptomatic and healthy needles. Watch our video here Collecting Tip and Needle Blight Samples

Plant Nematode Sample Submission

The PIDC provides soybean cyst nematode egg counts, information about thresholds and rotation information.  We also provide complete nematode counts for corn, turf, and other grassy plants.  

If your sample is from outside of Iowa do not submit it without contacting us we have strict limitations on soil movement.

Form and fee, do not send payment with your sample.  You will receive a statement from Iowa State University.

Digital Photography (Plant & Mushrooms)

Digital images of plants, plant problems and mushrooms 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.

Submitting a Mushroom for Identification

We are happy to assist in identification of fungi, see our submission form and guidelines at Sample Submission Form.

Wax paper or paper bags are the best material for packing mushrooms.
