KSU Plant Disease Diagnostic Lab Update - 3/26/2020

The KSU Plant Disease Diagnostic Lab continues to remain open at this time. However, we are working under limited operations and staff, so turn around may take a little longer than usual. There have been a few changes to our submission procedures. Please read the information below:

  • No in-person sample delivery to lab. Instead, if you are in Manhattan please use the soil drop box located on the Northwest side of Throckmorton PSC.
  • USPS sample delivery to 4032 Throckmorton PSC, 1712 Claflin Road, Manhattan, KS 66506 is still available, but will be checked at a minimum of twice a week. Time sensitive samples such as Wheat should NOT use USPS and instead use the new temporary address below.
  • The best mailing option for samples to the plant disease diagnostic lab is BELOW. Please email us the tracking # so we know that a sample is coming to the lab.
