Diagnostic Lab

Cornell Cooperative Extension – Monroe County provides a range of diagnostic services to identify plant problems and make recommendations for actions concerning soil pH, plants affected by disease or insects and the identification of household insects. With correct identification of a problem, effective treatment can be recommended. Detection and treatment of the exact cause prevents spread of the problem and further loss of plants on your property.

  • Diagnosis takes place in the laboratory of the Monroe County office.
  • Our Diagnostic Lab is equipped with microscopes and key resource guides.
  • Other tests are offered through lab facilities at Cornell University.
  • Please take time to read the requirements for submitting samples BEFORE bringing materials to the office.

If you suspect that disease or insects are causing a plant problem, our lab will examine the sample and provide you with written recommendations.

Soil is an essential factor in plant development and health. Many but not all plant problems are caused by poor plant selections for the site. Soil tests are recommended to determine whether an area can successfully support plant development. Cornell Cooperative Extension – Monroe County can provide pH testing as well as a more comprehensive nutrient analysis (through Cornell University) offering more details.

If you wish to submit a household insect sample for our evaluation, please read about the submission process. Through this site you can download and fill out necessary forms before visiting our office.
