Traditional Whole Plant Resistance Screening
Fresh plant samples should be mailed to the following address:
UT Weed Diagnostics Center
112 Plant Biotechnology Building
2505 EJ Chapman Drive
Knoxville, TN 37996
Attention: Jose Vargas
Plants will be
cultured in a germination chamber in order to
produce seed for resistance screening. Samples will be
seeded along with known resistant and susceptible standards and exposed to a
discriminatory rate of a single herbicide. All tests will be
replicated three times. In the event a
known resistant standard is not available for the weed submitted, samples will
be screened with known susceptible sample of the same species and exposed to a
discriminatory rate of herbicide.
In most cases, a report detailing results and providing control recommendations will be provided 16-20 weeks after sample
submission.
Cost
$1499 per sample for Tennessee residents / $1599 per sample for non-Tennessee residents
Molecular Resistance Confirmation
Fresh plant samples should be mailed to the following address:
UT Weed Diagnostics Center
112 Plant Biotechnology Building
2505 EJ Chapman Drive
Knoxville, TN 37996
Attention: Jose Vargas
Plants will be cultured in a germination chamber and DNA will be extracted from plant tissue and analyzed for target site mutations associated with herbicide resistance. In most cases, individuals submitting a sample will receive a report detailing results that also provides control recommendations within 3-5 weeks of sample submission.
