Rückstände von Carbendazim und anderen Fungiziden im Bienenhonig aufgrund der Blütespritzung von Winterraps

摘要: During 2000 to 2002, 91 Hessian spring honeys from regions with an extended cultivation of canola were analysed for residues the registered fungicides Carbendazim, Iprodion, Metconazol, Tebuconazol and Vinclozolin. The samples included 15 certified ecological apiaries. While Iprodion Metconazol not detected at all Vinclozolin only sporadic maximum levels 0,018 mg/kg, Carbendazim was found in 35,2 % up 0,118 mg/kg. eco did differ other samples. In May 2002 two isolated fields (9,8 resp. 5,5 ha) treated 11/ha Derosal® (active ingredient: 360 g/l Carbendazim) 600 l water/ha 1,5 l/ha Folicur® 251,2 Tebuconazol) 400 during full blossom while a third field served as untreated control. Three honey bee colonies placed close each four days before treatment. From hive, fresh taken seven after treatment Tebuconazol. one six control contaminated 0,080 mg/kg showed (average: 0,145 range: 0,061 - 0,227 mg/kg) five positive < DL- 0,025 mg/kg). Due its specific characters (slightly hydrophilic compared fungicides) application can result extremely high residue honey. meantime, manufacturers Thiophanate-methyl acknowledged these findings and, irrespectively toxicological relevance, stopped their deal such products on German market.
