Observationer som gjorts i departementen Gard och Vaucluse i s\u00f6dra Frankrike visar en h\u00f6g niv\u00e5 av symptom fr\u00e5n mildiou, en sv\u00e5r svampsjukdom, p\u00e5 flera f\u00f6rmodat svampresistenta druvsorter, ibland kallade piwi<\/em><\/strong>.<\/p>

\u00c4r detta ett bakslag f\u00f6r svampresistenta druvor?<\/p>

Det beh\u00f6ver det inte vara. I \u00e5r har m\u00e5nga ving\u00e5rdar i Frankrike f\u00e5tt osedvanlig kraftiga attacker av mildiou och i stort sett ingen av de svampresistenta druvor som finns p\u00e5 marknaden \u00e4r 100 % resistenta. Analyser g\u00f6rs nu f\u00f6r att f\u00f6rvissa sig om att mildiou inte har kommit runt dessa druvors resistans. Det vore naturligtvis allvarligare.<\/p>

P\u00e5 de drabbade ving\u00e5rdarna rekommenderar IFV, Institut Fran\u00e7ais de la Vigne et du Vin<\/strong>, att vinodlarna genom besprutning skyddar de svampresistenta vinrankorna p\u00e5 samma s\u00e4tt som de skyddar sina icke-resistenta druvor, s\u00e5 l\u00e4nge smittorisken \u00e4r s\u00e5 h\u00e4r h\u00f6g (en rekommendation \u00e4ven utan dessa angrepp).<\/p>

Svampresistenta druvor<\/strong> (ibland kallade piwi) \u00e4r korsningar mellan europeiska och amerikanska vinrankor. De amerikanska \u00e4r resistenta mot mildiou och oidium, tv\u00e5 svampsjukdomar som kom fr\u00e5n USA till Europa p\u00e5 1800-talet och sedan dess har skapat problem f\u00f6r vinodlarna h\u00e4r.<\/p>

Korsningarna, som \u00e4r s.k. \u201dhybrider<\/strong>\u201d eftersom de \u00e4r korsningar mellan tv\u00e5 olika familjer, den europeiska (Vitis vinifera<\/em>) och en amerikansk vinranka (Vitis n\u00e5got-annat<\/em>) har s\u00e5 pass mycket europeiskt \u201dblod\u201d i sig att smakprofilen blir bra men de kan d\u00e4rmed f\u00f6rlora lite av sin motst\u00e5ndskraft.<\/p>
