(2) The department will propagate and maintain pathogen-infected material for the purpose of testing or shoot-tip grafting.

Such plant material will be kept in enclosed structures on department-owned sites and destroyed when removed from the structure.

(3) Sites for dooryard citrus will be exempt from the nematode certification requirements.

(4) Nurseries producing citrus trees from cuttings or seed for the export trade or as boxed souvenirs shall be exempt from source tree registration as contained in Rule 5B-62.012, F.A.C., provided the cuttings come from a tree grown in a structure in accordance with Rule 5B-62.010, F.A.C., and the source tree has been tested annually and found free of citrus greening and severe strains of citrus tristeza virus. They shall not be exempt from annual testing fees.

(5) Registered tissue culture laboratories producing citrus in an approved lab environment shall be exempt from citrus nursery site approval as contained in Rule 5B-62.008, F.A.C. Tissue culture laboratories will also be exempt from the citrus nursery sanitation and structure requirements contained in Rules 5B-62.009 and 5B-62.010, F.A.C., provided the lab environment maintains standard operating procedures to minimize the spread of serious graft-transmissible diseases and other pathogens of citrus. This exemption only applies to plantlets maintained in the laboratory environment.
