On the occasion of the 2nd International Symposium on Carrot and Other Apiaceae (Poland, 19 - 22 September), Vilmorin - Mikado, the world leader for carrots, presents an innovative and environmentally friendly solution to combat the cyst nematodes Heterodera carotae. Currently in the research phase, this new “soil cleanup” variety could be brought to market in the next 2 to 3 years.
OBJECTIVE: TO REPLACE THE USE OF DICHLOROPROPENE
For a number of years, carrot producers have been making use of a dichloropropene - based nematicide for controlling the nematodes Heterodera carotae. Banned by the European Union in 2009, dichloropropene had been granted use exemptions in France, Spain, Italy and Portugal. In June 2018, the French Ministry of Agriculture definitively banned the use of this molecule. At present there are several thousand hectares in France and Italy that continue to be affected by Heterodera carotae.
APPROACHING 20 YEARS OF COLLABORATIVE RESEARCH
The “AOP Carotte de France” (a French National Association of Carrot Producing Organisations) initiated a collaborative project in 2002, which has since mobilised various partners : INRA ( French National Institute of Agricultural Research) that undertakes fundamental research ; technical partners for the field implementation and definition of the technical protocols (CTIFL: French Interprofessional Technical Centre for Fruit and Vegetables ; and SILEBAN: Investment and Development Company for Vegetable and Horticultural Crops in Lower Normandy, France), and Vilmorin - Mikado for the breeding of varieties. "Vilmorin - Mikado with the involvement of the partners has undertaken to develop a cleaner and more environmentally friendly solution by focusing research efforts on resistance to the nematodes Heterodera carotae" says Jacques - Yves Gueguen, Marketing Portfolio Lead for Roots and Bulbs at Vilmorin - Mikado.
The cyst nematode, Heterodera carotae, is responsible for causing significant yield losses due to a high number of short, split carrots or carrots having a hairy appearance due to excessive production of lateral roots. In production zones in sandy terrain, commercial losses can reach up to 90%.
A WILD TYPE VARIETY THAT WORKS AS A TRAP CROP
Selected from more than 3700 wild plants, this new variety is not a consumable carrot. White in colour, resembling a type of wild carrot, it has a
