2. Surface Sampling and Automated Liquid Membrane Extraction of Fungicides
Abstract : A number of approaches for fungicide determination are presented. A surface sampling technique is utilised for the determination of fungicide foliar residues on greenhouse surfaces, mainly leaves. The procedure is based on solvation of the fungicides on the leaf surface with ethanol and HPLC analysis. READ MORE
