We assist a wide variety of people experiencing problems with plants and pests. There are many things that cause plant problems. Our laboratory specializes in diagnosing problems caused by arthropods (insects, mites, ticks, etc.), pathogens (fungi, bacteria, viruses), and nematodes.

Here are some of the samples we accept for diagnosis:

  • Plants or plant parts for insect, pathogen and nematode analysis
  • Insects, mites, ticks, spiders and other arthropods for identification
  • Soil and tissue samples for nematode analysis
  • Weeds and plants for identification

Samples may be submitted to the lab by mail or dropped off at our facility.  We will analyze the sample for a nominal fee and provide a diagnosis or identification of the problem as well as recommendations for control.
