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 & 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 identifying mushrooms, we focus on these found associated with plants or found in natural habitats. See our submission form and guidelines at Sample Submission Form.

White mold, with a focus on vegetables

Introduction and overview


White mold is caused by the fungal pathogen Sclerotinia sclerotiorum and can be devastating to a wide range of plant hosts. This fungus is a generalist, meaning that it has a wide host range. Hosts for S. sclerotiorum range from the large-scale production soybean to gardener-cultivated vegetables including tomato, pepper, beans, crucifers/cole crops (cabbage, Brussels sprouts, etc.) and more.
