France is the second largest European producer, behind Germany, of radishes. Each year, France produces 48,000 tons of radishes. Damage to radishes from root maggots must be prevented in order to produce a marketable crop. But since 2007 no insecticide has been registered in France for use against root maggots. Emergency uses of unregistered insecticides have preserved the industry. A recent analysis calculated the economic costs of not having effective insecticides available.

“The additional costs caused to replace a chemical treatment by a manual operation (manual sorting at harvest) is calculated at 6,905 €/ha. At the sector level, the lack of availability of a registered plant protection product against vegetable flies would thus lead to a direct loss of 18,600,000 €. This loss in profitability seriously impacts the viability of the radish production sector in France and puts at the stake the employment directly and indirectly involved in this sector. To give an indication, in Loire-Atlantique this sector has significant weight representing 2,500 FTEs (Full Time Equivalent). … The risk of distortion of competition in the French radish production sector is real vis-à-vis other European countries where pressure of the vegetable flies is less.”
