 Pre-treatment and planting
                            Pre-treatment and planting
                            - Annabelle has a short dormancy.
                            - Keep the seed in refrigerated storage to prevent physiological aging and
                              dehydration of the seed.
                            - Allow the seed to acclimatize to the local conditions before planting.
                            - Planting with small white sprouts produces the best results.
                            - Plant 3 cm deeper than for normal use. This effects the rooting system and the
                              absorbtion of nutrients favourably.
                            - When product is grown for long term storage, the fungicide Azoxystrobine is preferred. This
                              will prevent Silver Scurf.
                            - Always treat SEEDS AND SOIL against Rhizoctonia.
                            - Cutting of the big sizes can be done, in that case, be sure of dry cricumstances.
                            - Be sure of dry cricumstances. Let the seed cure direct. Optimum results from 3-4
                              weeks prior to planting.
 Growing attentionpoints
                            - Post-emergence, use Metrubuzin (Sencor) the low doses system.
                            - Annabelle seems susceptible to Centium, also in combination with other herbicides.
                            - Keep the foliage vigurous until tubers have reached 45 mm.
                            - Top dressing should only be given in limited quantities.
                            - Over fertilisation will restults in a higher sensitivity of Late Blight.
                            - Ensure early treatments against Late Blight (Phytophthora)
                            - Later on during the season, switch over to remedies with a better tuber protection.
                            - Irrigation provides a regular growth and uniform product with better cooking quality.
                            - Don't overirrigate, as it will result in poor quality and on some soiltypes a higher risk
                              of Powdery Scurf.
 Haulmkilling and harvest
                            - For an optimum dormancy, haulm killing should take place on a mature crop.
                            - Aim for a product with a dry matter content of 19,7 %
                            - Ensure at least 3 weeks between haulm killing and harvest to have a better skin set.
                            - The tubers should be fully skin set before harvest.
                            - Avoid harvest damage at all times.
                            - Micro - damage will end in more dehydration and early sprouting.

                            - Because of the short dormancy and susceptibility to Fusarium,extra attention
                              should be paid on storage.
                            - If harvested under normal conditions, refregiration can begin very shortly after curing.
                            - For storage longer than 2 months, refregiration is required.

                            REFRIGERATED STORAGE
                            - Refrigerate with a small difference between cooling temperature and product
                              temperature to limit loss of weight.
                            - Cooling regime of 0,5 - 0,7 degrees a day, to a stable temperature of 4-5 degrees.
                            - Storage lower than the advice results in increased sweetening.
                            - Ventilate regularly but shortly to avoid Co2 accumulation.
                            - Every fluctuation in temperature, in combination with formation of condensation, results in
                              earlier sprouting and an enlarged risk of silver scurf.

                                                                                                                          23 Mar 2012
