(b)

no potato cyst nematodes have been found during the last two successive official investigations in samples of 1 500 ml soil/ha and no potatoes or other host plants listed in point 1 of Annex I, other than those for which an official investigation is required according to Article 4(1), have been grown after the first official investigation;

or

(c)

no potato cyst nematodes or potato cyst nematode cysts without live content have been found in the last official investigation which must have consisted of a sample size of at least 1 500 ml soil/ha and no potatoes or other host plants listed in point 1 of Annex I, other than those for which an official investigation is required according to Article 4(1), have been grown in the field since the last official investigation.

Results of other official investigations carried out before 1 July 2010 may be considered as official investigations as referred to in subparagraphs (b) and (c).

6. By way of derogation the standard size of the soil sample referred to in paragraph 1 may be reduced to a minimum of 200 ml of soil/ha provided that the field is situated in an area declared free from potato cyst nematodes, and designated, maintained and surveyed in accordance with the relevant International Standards for Phytosanitary Measures.

ANNEX III U.K.

SECTION I U.K. VERIFICATION

With reference to Article 5(2), the official investigation referred to in Article 4(1) shall establish that at the time of verification one of the following criteria are met:

• no history of potato cyst nematodes in the field during the last 12 years, based on the results of appropriate officially approved testing,

or

• a known cropping history in which no potatoes or other hosts plants listed in point 1 of Annex I have been grown in the field in the past 12 years.

SECTION II U.K. SURVEYS

The official surveys referred to in Article 6(1), shall be conducted on at least 0,5 % of the acreage used in the relevant year for the production of potatoes, other than that intended for the production of seed potatoes. The results of the surveys shall be notified to the Commission by 1 April for the previous 12 month period.

SECTION III U.K. OFFICIAL MEASURES

(A) The officially approved measures referred to in Article 4(4)(c), 9(1)(b) Article 10(1)(c) and in paragraph 2b of Annex I are: U.K.

1.

disinfestation by appropriate methods such that there is no identifiable risk of the potato cyst nematodes spreading;

2.

removal of soil by washing or brushing until practically free of soil such that there is no identifiable risk of the potato cyst nematodes spreading.

(B) The officially approved measures referred to in Article 10(1)(b) are delivery to a processing or grading plant with appropriate and officially approved waste disposal procedures for which it has been established that there is no risk of the potato cyst nematodes spreading. U.K.

(C) The officially approved measures referred to in Article 13 are an official re-sampling of the field officially recorded as infested as referred to in Article 8(1) or 8(2), and testing using one of the methods specified in Annex II, after a minimum period of six years counting from the positive confirmation of potato cyst nematodes, or counting from the growing of the last potato crop. This period may be reduced to a minimum of three years if appropriate officially approved control measures have been taken. U.K.

ANNEX IV U.K.

SECTION I U.K. DEGREE OF RESISTANCE

The degree of susceptibility of potatoes to potato cyst nematodes shall be quantified according to the following standard scoring notation as referred to in Article 9(2).

The score 9 indicates the highest level of resistance.

Relative susceptibility (%)	Score
< 1	9
1,1-3	8
3,1-5	7
5,1-10	6
10,1-15	5
15,1-25	4
25,1-50	3
50,1-100	2
> 100	1

SECTION II U.K. PROTOCOL FOR RESISTANCE TESTING

1. The test shall be performed in a quarantine facility either outside, in glasshouses, or in climate chambers. U.K.

2. The test shall be performed in pots each containing at least one litre of soil (or suitable substrate). U.K.

3. The soil temperature during the course of the test shall not exceed 25 °C and adequate watering shall be provided. U.K.

4. When planting the test or control variety one potato eye plug of each test or control variety shall be used. Removal of all stems except one is recommended. U.K.

5. The potato variety ‘Désirée’ shall be used as a standard susceptible control variety in every test. Additional fully susceptible control varieties of local relevance may be added as internal checks. The standard susceptible control variety may be changed if research indicates that other varieties are either more suitable or more accessible. U.K.

6. The following standard populations of potato cyst nematodes shall be used against pathotypes Ro1, Ro5, Pa1 and Pa3: U.K.

• Ro1: population Ecosse

• Ro5: population Harmerz

• Pa1: population Scottish

• Pa3: population Chavornay

Other potato cyst nematode populations of local relevance may be added.

7. The identity of the standard population used shall be checked using appropriate methods. It is recommended that at least two resistant varieties or two differential standard clones of known resistance capacity are used in the test experiments. U.K.

8. The potato cyst nematode inoculum (Pi) shall consist in total of five infective eggs and juveniles per ml of soil. It is recommended that the number of potato cyst nematodes to be inoculated per ml of soil is determined in hatching experiments. The potato cyst nematodes may be inoculated as cysts, or combined as eggs and juveniles in a suspension. U.K.

9. The viability of the potato cyst nematode cyst content used as the inoculum source shall be at least 70 %. It is recommended that the cysts are 6-24 months old and are kept for at least four months at 4 °C immediately prior to use. U.K.

10. There shall be at least four replicates (pots) per combination of potato cyst nematode population and potato variety tested. It is recommended to use at least 10 replicates for the standard susceptible control variety. U.K.

11. The duration of the test shall be at least three months and the maturity of developing females shall be checked before breaking up the experiment. U.K.

12. Potato cyst nematode cysts from the four replicates shall be extracted and counted separately for each pot. U.K.

13. The final population (Pf) on the standard susceptible control variety at the end of the resistance test shall be determined by counting all cysts from all replicates and the eggs and juveniles from at least four replicates. U.K.

14. A multiplication rate of at least 20 × (Pf/Pi) on the standard susceptible control variety shall be achieved. U.K.

15. The coefficient of variation (CV) on the standard susceptible control variety shall not exceed 35 %. U.K.

16. The relative susceptibility of the tested potato variety to the standard susceptible control variety shall be determined and expressed as a percentage according to the formula: U.K.

Pf_{test variety}/Pf_{standard susceptible control variety} × 100 %.

17. If a tested potato variety has a relative susceptibility of more than 3 %, cyst counts will suffice. In cases where the relative susceptibility is less than 3 %, eggs and juveniles shall be counted in addition to cyst counts. U.K.

18. Where the results of tests in the first year indicate that a variety is fully susceptible to a pathotype, there is no requirement to repeat these tests in a second year. U.K.

19. The results of the tests shall be confirmed by at least one other trial performed in another year. The arithmetic mean of the relative susceptibility in the two years shall be used to derive the score according to the standard scoring notation. U.K.
