Hello Marvin,

You are asking for two things here:

FOR GRASS SAMPLES:

To get an accurate description you would have to send this to the Plant and Pest Diagnostic Lab and have their turf experts look at it - Link:

https://www.canr.msu.edu/pestid/submit-samples/

First, send those images to <personal data hidden>. In your e-mail provide a detailed description of cultural practices (irrigation, fertilization, pesticide application, etc.) and include your contact information (phone, address, and e-mail information)

DO THIS BEFORE YOU SEND THE SAMPLE!! BECAUSE IF YOU NEED TO SEND A SAMPLE THEY (THE LAB) WILL TELL YOU

If you need to send a sample here is how you do it.

Residential Turf: Include a square of turf from the margin of the diseased area so that both healthy and diseased turf is included. Minimally, the turf square should be 6 inches x 6 inches. An intact layer of soil should remain on the root system. Wrap samples in newspaper and pack them in a box for shipment. Do not add moisture to the turf prior to shipment. Provide a detailed description of cultural practices (irrigation, fertilization, pesticide application, etc.) and images of the symptoms in the lawn with the sample.

Ship or Deliver Samples Directly at:
