A study in February that found pesticide residues in 90 percent of the French wines tested created an uproar. Pesticide residues were even found in organic wines, indicating contamination from neighboring vineyards or other sources. French vines are susceptible to a contagious bacterial disease, flavescence dorée, transmitted by a leafhopper. Treatment with pesticides is required by French law in several winegrowing regions, including Burgundy. One organic producer in Burgundy has now been charged with breaking the law for refusing to use Pyrevert, a pyrethrin pesticide. He says there is no evidence that his vines are infected, and argues that Pyrevert, a neurotoxin, is nonspecific to leafhoppers and kills beneficial insects as well. He faces six months of prison time and a fine of 30,000 euros, or about $41,000. Another organic grower was fined 1 euro after he agreed to use pesticides.Update here.
