| The use of scab resistant apple varieties is the best way to prevent infections of apple scab (Venturia inaequalis). In 1995 the then 10 most promising resistant apple varieties for Denmark where planted at Research Centre Årslev, Denmark in an organic production system. Three different cover crops where established in the alleyways. Weed cleaning in the tree row was done mechanically and the trees were kept unfertilised. The annual shoot growth, nutrients in leaf sample, mineralised nitrogen in soil, content of water in the upper 50 cm soil, fruit yield and fruit quality were assessed. The annual cover crop caused the longest shoot growth, the highest content of nitrogen in leaves and soil, the smallest competition with the trees concerning soil water... |

| In a questionnaire send out in the mid 90’ties, organic growers estimated a yield reduction of at least 86 per cent compared to conventional production. The estimation was based on production of the most common conventional grown varieties. The main reason for this low productivity is lack of control methods against diseases and pests, especially apple scab (Venturia inaequalis) (Lindhard et al., 1998). In Denmark, most organic pesticides are not registered. For instance, copper has not been on the market for 7 years. |

| Økologisk dyrkning stiller særlige krav til sortsvalget, som bør bestå af sorter, som er modstandsdygtige over for æblernes mange skadevoldere. I mange år har de professionelle sortsforædlere derfor satset på at udvikle sorter, som er resistente over for æbleskurv, der er den værste svampesygdom på æble. Desværre er skurvresistensen i de seneste år blevet brudt, og de tidligere resistente sorter kan nu angribes af skurv. Det betyder fornyet fokus på at finde egnede sorter til økologisk dyrkning, og det har været et mål for projekt "Fruitgrowth" som har løbet i perioden 2010-2014. |

| Den danske produktion af æbler er lille og ustabil pga. udbytte- og kvalitetstab forårsaget af skadedyr og sygdomme.Projektet FruitGrowth fokuserer på robuste sorter, nye innovative metoder til ukrudtsbekæmpelse og ny lagringsteknologi. Der arbejdes med løsninger på kort og langt sigt for de alvorligste skadevoldere, bl.a. nyttedyr i blomsterbræmmer og naturstoffer til bekæmpelse. |

| Hvilken sort er bedst til økologisk dyrkning? Intet sted er sortsvalget mere vigtigt end i æbledyrkning. Valget har konsekvenser mange år frem, da træerne optimalt set skal dyrkes 12-15 år for at få en effektiv og rentabel produktion. Sorterne skal vælges, så problemerne med de mange skadevoldere, som i varierende grad angriber sorterne, kan holdes i skak uden den store indsats af bekæmpelsesmidler. Oveni kommer krav til sortens produktivitet, træets dyrknings lethed og ikke mindst æblernes udseende, kvalitet og holdbarhed. I mange år har der til økologisk produktion været fokus på sorter, som var resistente overfor skurv, der er den mest dominerende sygdom på æbler. Desværre har denne strategi vist sig at være en blindgyde, da en ny race af... |
