The New Jersey Department of Agriculture's Plant Laboratory provides laboratory support for regulatory and service programs affecting the producers, dealers, and consumers of plant products in New Jersey. Our focuses are seed analysis, honeybee disease screening, and plant pathogen screening.

Analyses performed for seed quality include germination, purity, noxious weed, vigor, and varietal . These tests are performed either using microscopy techniques by trained laboratory technicians or conducted and housed in special climate-controlled growth chambers. Testing of seeds for phytosanitary export requirements is also done. Fees are charged for service tests.

Honey bee analysis includes disease screening for Nosema and Varroa using microscopy techniques and applied field techniques.

Plant pathology testing is performed for the identification of both seed-borne and nursery diseases. Both microscopic and enzyme linked immunosorbent assay (ELISA) tests are employed.

It is the responsibility of the individuals submitting the samples to see that the samples are representative of the lots from which they were takenSamples should be submitted using our submission form, which you can download here

    At least 1000 seeds should be submitted for a germination evaluation. A standard germination test requires 400 seeds; another 400 seeds are needed in the event that a retest is necessary.A New Jersey State noxious weed seed examination is conducted as part of the purity analysis.

    A seed test report, applying only to the sample submitted, will be provided to the sender along with an itemized bill. When requesting a test on seed that has been previously analyzed, a copy of this analysis should accompany the sample as well as the reason for requesting a new analysis.
