A new mobile
lab gives University of
Nebraska-Lincoln Extension the ability to diagnose crop
diseases on-site.
The Mobile
Plant Diagnostic Lab was funded by the U.S. Department of
Homeland Security and UNL Extension, said Loren Giesler, plant
pathologist in the university’s Institute of Agriculture and
Natural Resources.
”The goal of
the mobile lab is to be available to respond to any potential
agrosecurity threat,” he said. This includes detecting and
reporting new or unusual pathogens in Nebraska crops whether
they occur intentionally, accidentally or naturally.
In addition,
the lab will be available at UNL Extension field days throughout
the state for farmers to bring in plant samples.
”This will
increase public awareness of plant pathogens and aid farmers in
diagnosing plant diseases,” Giesler said. Before the mobile lab,
farmers had to mail plant samples to the university’s Plant and
Pest Diagnostic Clinic in Lincoln, a process that could take
several days before results are known. The mobile lab eliminates
the wait for test results.
“If a grower
brings a plant sample to a field day, it most likely can be
diagnosed on-site before they go home,” he said.
Among the
diseases the mobile lab could detect is soybean rust, which
first was detected in the United States last fall in several
southeastern states. If soybean rust would enter Nebraska, the
mobile lab would allow UNL plant pathologists to test for the
disease on-site.
”We could
know within two hours if the plant sample tested positive for
soybean rust,” Giesler said. The lab is equipped with the latest
technology and equipment, including molecular diagnostic tools
and satellite transmission, which would allow UNL to inform
state and federal agencies quickly about detection of any
disease as well as link them to national experts through digital
media.
”Whether
detecting a disease as serious as soybean rust or identifying a
more common disease, such as brown spot in soybean, stripe rust
in wheat or gray leaf spot in corn, the lab gives extension a
valuable resource for controlling and containing plant
diseases,” Giesler said.
