Diagnostic Services

Current Massachusetts and University policy have the effect of temporarily suspending most of the on-campus services that we provide, including but not limited to:

  • Soil and Plant Nutrient Testing Lab
  • Plant Disease Diagnostics Lab
  • Weed, Insect, Turfgrass, and Invasive Plant Identification

These services are currently suspended. Until further notice, please do not send or deliver samples to the campus, as we cannot process them.

A UMass Laboratory Diagnoses Landscape and Turf Problems - When normal services resume, the UMass Extension Plant Diagnostic Lab is available to serve commercial landscape contractors, turf managers, arborists, nurseries and other green industry professionals. It provides woody plant and turf disease analysis, woody plant and turf insect identification, turfgrass identification, weed identification, and offers a report of pest management strategies that are research based, economically sound and environmentally appropriate for the situation. Accurate diagnosis for a turf or landscape problem can often eliminate or reduce the need for pesticide use.

Soil and Plant Nutrient Testing - When normal services resume, the University of Massachusetts Soil and Plant Nutrient Testing Laboratory is located on the campus of The University of Massachusetts at Amherst.
