1. The plant material, as appropriate, shall be subjected to appropriate therapy procedures as laid down in FAO/IPGRI Technical Guidelines.

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. Plant material intended for approval for official release shall be held under conditions conducive to a normal cycle of vegetative growth and be subjected to visual inspection for signs and symptoms of harmful organisms including all relevant harmful organisms listed in Directive 2000/29/EC, on arrival and subsequently, at appropriate times, during the period of the indexing procedures.

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:

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:

(a)

Citrus greening bacterium

(b)

Citrus variegated chlorosis

(c)

Citrus mosaic virus

(d)

Citrus tristeza virus (all isolates)

(e)

Citrus vein enation woody gall

(g)

Naturally spreading psorosis

(h)

Spiroplasma citri Saglio et al.

(k)

(l)

Witches' broom (MLO)

(m)

Xanthomonas campestris (all strains pathogenic to Citrus).

3.2.

For diseases such as Blight and Blight-like for which there are no short-term indexing procedures the plant material must be subjected upon arrival to shoot-tip grafting onto seedling stock grown under sterile culture as set out in FAO/IPGRI Technical Guidelines, and the resulting plants subjected to therapy procedures according to point 1.

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.
