Section 3015.3 - Inspection and Testing Procedures for Prunus Species(a) Generally. Inspection and testing procedures prescribed in this article for an applicant's plantings will be made by the Department and shall be conducted at times determined as suitable by the Department. In the indexing procedures required in this section, the Department may approve the substitution of other indicator plants, if equally suitable, or may approve other procedures for testing for virus infection if determined equally suitable. Additional inspections or tests other than provided in this section may be required by the Department if seasonal conditions or other factors tend to obscure virus symptoms or make adequate inspection impossible, or when virus infection is suspected, or when virus symptoms may be masked in a particular variety. (1) At the Department's discretion and under its close supervision, the applicant may provide the Shiro-fugen cherry indicator trees and the labor to collect budwood from selected trees and to perform the budding and related testing tasks. However, the Department shall make all of the disease readings and determinations.(b) Qualification of Stock. (1) Registered Trees--Mother Block. Each registered tree in the mother block shall be tested each year by indexing in Shiro-fugen cherry or by other methods approved by the director for the detection of Prunes ring-spot virus and prune dwarf virus and shall be visually inspected prior to stock distribution.(2) Registered Trees--Scion Orchard. Registered trees in a scion orchard shall be indexed in Shiro-fugen cherry or by other methods approved by the director for the detection of Prunes ring-spot virus and prune dwarf virus and visually inspected each year in which scion wood is harvested.(3) Seed Source Trees. A Prunes species tree may be registered as a seed source tree after being tested by indexing in Shiro-fugen cherry or by other methods approved by the director for the detection of Prunes ring-spot virus and prune dwarf virus and at least one visual inspection.(4) Nursery Increase Block, Certified Block. At least one visual inspection shall be made each year of plants in a nursery increase block or in a certified block.(5) Information regarding other methods approved by the director in (1), (2) and (3) may be obtained from the Department's Pest Exclusion Unit.(c) Refusal, Suspension or Cancellation of Registration or Certification. Registration or certification may be refused, suspended or canceled for any plants in part or all of a planting if: (1) The requirements of this article have not been met.(2) The plant is found to be virus-infected or off-type.(3) A registered tree is found virus-infected and it is determined that plants propagated from it also are liable to be infected.(4) Yellow leaf roll virus disease of peach is found within 300 feet.(5) The pest cleanliness requirements for nursery stock in the nursery inspection regulations, Section 3060.2, have not been met.(6) An accumulated percentage of more than 1/2 percent of the trees of the same variety on the same kind of rootstock are found virus-infected in an increase block or more than 2 percent in a certified block unless all such virus-infected trees are removed under the supervision of the Department. Either visual inspections or the results of indexing or both may be used as a basis for calculating the number of trees that may be infected.(7) For any reason the identity of a plant becomes uncertain or has not been properly maintained.(8) A registration number is misused or misrepresented.(9) Registered stock is not used primarily to produce certified nursery stock.Cal.
