(a) For the purpose of meeting the USDA-APHIS-PPQ requirements
for movement of citrus plants out of an area quarantined for citrus
greening or citrus canker by USDA and the Department, and for interstate
movement in accordance with USDA requirements, the Texas State Certified
Clean Citrus Stock Program, consists of:
(1) All citrus plants that have been propagated in
accordance with subchapter D of this chapter (relating to Citrus Nursery
Stock Certification Program), or in a structure that meets the requirements
of USDA-APHIS for interstate movement from an area quarantined for
citrus greening or citrus canker; and
(2) Propagated with certified budwood from a recognized
and approved budwood source;
(3) Propagated from budwood that originated from a
certified increase tree;
(4) Propagated in a continuous progression of certified
trees from generation to generation wherein that the original trees
were propagated using certified budwood and all progeny propagated
and/or used as a source of budwood are identified in a manner to clearly
trace the original source of budwood, the year the original budwood
was purchased and labeled in accordance to §21.36(j) of this
title (relating to Increase Trees and Increase Blocks); or
(5) For noncommercial varieties for which certified
budwood is not available and which are not to be moved into the Citrus
Zone, budwood source trees must have been tested for citrus tristeza,
citrus greening or any other pest of regulatory concern within 12
months prior to use for budwood. Nursery stock resulting from the
budwood of these varieties shall be sampled and tested according to
the USDA-APHIS-PPQ requirements for movement of citrus plants out
of a quarantined area. The Department will inspect trees for citrus
canker and other pests of regulatory concern during facility inspection.
(b) Samples will be collected by the Department for
testing in accordance with the sampling plan, "Survey Protocol
in Exclusionary Facilities for the Interstate Movement of Citrus and
Other Rutaceous Plants for Planting from Areas Quarantined for Citrus
Greening, Asian Citrus Psyllid, and Citrus Canker," developed
by the CPHST Plant Epidemiology and Risk Analysis Laboratory of the
Plant Protection and Quarantine branch of USDA-APHIS. The cost of
the laboratory analysis of the samples shall be borne by the owner
of the citrus nursery.
