2. The plant material, following the therapy procedures carried out pursuant to point 1, shall be subjected to indexing procedures in its entirety. All plant material including indexing plants, shall be held at the approved facilities under the quarantine containment conditions laid down in Annex I.

U.K.

3. For the purposes of point 2, the plant material shall be indexed for harmful organisms (tested for and identified) according to the following procedures: U.K.

3.1.

The testing shall use appropriate laboratory methods and, where appropriate, indicator plants, including Citrus sinensis (L.) Osbeck, C. aurantiifolia Christm. Swing, C. medica L., C. reticulata Blanco and Sesamum L., in order to detect at least the following harmful organisms:

4. The plant material subjected to the visual inspections referred to in point 2 and on which signs and symptoms of harmful organisms have been observed shall be subjected to an investigation including testing where necessary, to determine, as far as possible, the identity of the harmful organisms causing the signs and symptoms.
