Standard analysis includes identification of most plant pathogenic fungi and bacteria as well as cultural and physiological conditions that are apparent and may be responsible for plant problems. If identification of genus and species is required of bacterial isolates see "Bacterial Identification" below.
Samples suspected of viral infections are tested for virus presence using serological test methods. These methods require a determination of the suspected virus to perform testing and very in cost. Each individual case needs to be discussed to determine the appropriate tests to be run and the final cost of the procedures. The procedure may take a number of days depending on the virus suspected. Please submit a number of leaves or other pieces of symptomatic tissue. The fee for this service is individually based.
The Clinic uses Biolog technology to identify any bacterial isolates needing identification to species level. A pure culture is required to perform the procedure with some incubation time. Please be aware that the isolation process and Biolog plating may ake 5-7 days to complete.
Phytopthora or ELISA Test:
The clinic uses an Enzyme-Linked ImmunoSorbent Assay (ELISA) to detect Phytophthora in some plant tissues. This test may be used where Phytophthora may not be readily isolated or where isolation may be time consuming, and a rapid diagnosis is desired. The test detects Phyophthora only to the genus level. ELISA testing is also available for a few other specific pathogens. Please contact the Clinic for details.
All parts of the plant, root, crown, and leaf blades, are examined on each turf sample submitted to the Clinic. Nematodes are a growing concern on many golf courses and turf farms, if they are suspected please see the nematode analysis area below. Each sample submitted will receive a written Diagnostic Reply which explains the findings and lists any available control recommendations.
The majority of our nematode analysis is performed using the pie pan method. This method requires a 5 day extraction period prior to identification of the nematodes present in the sample. Each sample submitted will receive a written Diagnostic Reply which explains the findings and lists any available control recommendations.
Turf & Nematode Analysis:
This procedure includes the standard turf analysis and the additional nematode analysis for a sample. See the descriptions for each of these procedures listed individually above.
Soil Testing or Nutritional Analysis:
For soil analysis or nutritional analysis would be useful, submit the sample directly to the Cornell Nutrient Analysis Lab.
If you suspect insect damage, submit the sample directly to the Insect Diagnostic Lab.
