Study of Carbendazin Residue Accumulation on Greenhouse and Field-Grown Strawberries, after Successive Treatments with Benomyl

Abstract

Benomyl, a systemic fungicide used In preharvest treatments to prevent Botrytls and other fungal diseases, metabolizes to carbendazlm (MBC). A study was undertaken to determine if the total residues of MBC of greenhouse and field-grown Douglas strawberries accumulate In fruits after successive fortnightly treatments with a commercial preparation of benomyl. Statistical analysis of the data obtained Indicates that residues of MBC do not accumulate In fruits; on the contrary, they decrease over time.

Analysis of Carbendazim in Agricultural Samples by Laser Desorption and REMPI Time-of-Flight Mass Spectrometry

“…Thus, its analysis is carried out in an indirect way by the detection of some thermally stable derivatives . Due to this unstability, the technique usually employed for the analysis of carbendazim is reversed-phase HPLC with fluorescence or ultraviolet detection; , this technique requires a long procedure for the separation and extraction of the compound prior to its analysis. ,, The detection limit of the conventional method for the analysis of benzimidazoles adapted to carbendazim is 0.02 mg/kg for 5-mg samples and 0.01 mg/kg for 8-mg samples . An easier supercritical fluid extraction (SFE)-HPLC method for the determination of carbendazim in lettuce samples has been described, but with higher detection limit …”

Study of Agricultural Samples by Laser Desorption Coupled With Resonance‐Enhanced MultiphotonIonization and Time‐of‐Flight Mass Spectrometry: Application to Carbendazim Analysis in Pepper

“…Carbamate pesticides have been mainly analysed by gas chromatography (GC) [8,9] and high performance liquid chromatography, (HPLC) [10][11][12]. Since carbendazim is a labile compound, the technique usually employed for the analysis of carbendazim is reversed phase HPLC with fluorescence or ultraviolet detection [13,14]; this technique requires a long procedure for the separation and extraction of the compound prior to its analysis [10,15,16]. The detection limit of the conventional method for the analysis of benzimidazoles adapted to carbendazim is 0.02mg/kg for 5mg samples and 0.01 mg/kg for 8 mg samples [17].…”
