Three Main Areas:
1. Nursery Certification Program
2. Export Certification Program
3. Survey & Detection Program
Entomology Program *Responsible for regulatory activities
NDA is charged with administering and enforcing
the standards and restrictions spelled out in the
Plant Protection and Pest Act.
Nursery Certification
Nebraska law requires all persons that distribute perennial
or woody plant material to be licensed with the Nebraska
Department of Agriculture
In 2014, NDA licensed
approximately 1250 Nursery
Stock Distributors in
Nebraska.
Additionally, about 300
licensees requested
certification of Nebraska
Grown Nursery Stock.
Export Certification
Many foreign countries and other state have specific pest
freedom requirements that must be met so plants and plant
products are able to enter those countries or states.
NDA conducts inspections in order to determine if the
products meet the entry requirements set by the receiving
entity.
If requirements can be met, NDA will
issue the appropriate export certificate.
In 2014, NDA conducted roughly 600
phytosanitary inspections and issued over
4,700 export certificates.
Several states have enacted state
exterior quarantines regulating
European Corn Borer. NDA
issued ECB licenses to 134
firms, and reviewed over 4,000
certificates for loads of corn
shipped to states with ECB
quarantines.
Export Certification
NDA also conducts Growing Season inspections of seed
fields in the state, to determine presence or absence of
various diseases and weeds.
Survey & Detection
Surveys for exotic and invasive plant pests are conducted by
NDA for several reasons:
• Determine presence or absence of a pest
• Delimit a known infested area
• Determine the feasibility of an eradication effort
• Maintain pest free status
• Facilitate trade

Jessica Schueth
Export Certification Coordinator •Native to Asia.
•First discovered in Detroit,
MI in June 2002.
•Likely introduced to the
US on solid wood packing
material 20+ years ago
•Now found in 25 states and 2
Canadian provinces.
•Closest infestations to Nebraska are
in the Kansas City, KS/MO and
Boulder, CO metro areas.
•EAB has resulted in the loss of
millions of ash trees in infested
areas
•Ash firewood •Ash nursery stock
•Ash logs/lumber
•Agrilus planipennis
•Adults are approximately
¼” to ½” in length
•Small, shiny metallic-green beetle
•Larvae grow to about 1” in length

•D-shaped exit holes
•Serpentine galleries
under bark
•Small, vertical splits in the bark
•Thinning & die-back
of canopy
•Epicormic shoots sprout from main trunk
•Woodpecker damage
CHEMICAL—Preventative treatments
may protect trees
Treatments are only recommended if
within 15 miles of a known infestation
ERADICATION—Trees found to be
infested are removed
Chemicals include:
Imidacloprid & Emamectin benzoate
QUARANTINES—State & Federal
quarantines are put in place to prevent
movement of regulated articles
• TCD is a pest complex causing
decline & death in black walnut.
• Caused by a fungal pathogen carried on the walnut twig beetle.
• Currently found in all
states west of Nebraska,
from Colorado to California
plus Indiana, Maryland,
North Carolina, Ohio,
Pennsylvania, Tennessee
and Virginia.
• The walnut twig beetles are
exceptionally small. Over
23,000 beetles are in this 2” vial!
• Adult beetles may be present from
late winter to late fall.
• Symptoms of TCD include flagging,
yellowing & thinning of canopy, death of
branches, wilting foliage, & death of tree.
• The beetle attacks in large numbers.
The fungus infects the beetle galleries,
causing the cankers.
•No known cure.
•No known preventative treatment.
•Mitigation treatments are being developed.
•Approximately 12 states, including Nebraska, have
