Carrots are part of the carrot species of the ‘Daucus carota’ family, of which chervil, parsnip, dill and caraway are members as well. The carrot fly is a feared degenerative in carrots, and may already be treated from the end of April. Although the plant defends itself against damage by wound root formation, this blocks the food and juice flows.
From rough grounds, bushes and other sheltered places, the insects spread over large distances and lay their elongated eggs at the base of the crops. Carrots that have been in the fields for a longer period of time often need to be protected against damage by the carrot fly twice. The Wingssprayer spraying technique works extremely efficient and penetrates deep into the dense carrot leafage where these attackers are hiding.
