Regulation No. 2. No chestnut tree nursery stock shall be removed from
any nursery or other place where the same may be growing, for the
purpose of sale or shipment until said trees shall first have been
inspected by this Commission and the official inspection tag attached
thereto. “Removed” is here construed to mean the final tying up into
an original package, transporting from the premises where grown, or
offering same to a common carrier for shipment.
Regulation No. 3. All chestnut tree nursery stock intended for sale
or shipment must first be dipped into an approved fungicide prior to
delivery or shipment. The official inspection tag will not be attached
to stock unless first so treated.
Regulation No. 4. All chestnut tree nursery stock found to be infected
with the chestnut bark fungus must be immediately destroyed. This
regulation applies to diseased stock found at the time of inspection
for shipment, and also to inspections in the nursery before stock is
marketed.
Regulation No. 5. Nurserymen and common carriers, who, after receiving
notice of the above regulations, negligently or willfully fail to
refuse to be governed thereby, will, without further notice, subject
their chestnut stock and shipments to quarantine, which will be
maintained by this Commission.
All correspondence relative to nursery inspection should be addressed
to Dr. F. D. Heald, Pathologist, Zoology Building, University of
Pennsylvania, Philadelphia, Pa.
