✦ Synopsis

The reduction in residue levels of fenpropathrin with time after treatment of tomatoes and green beans, grown in two types of commercial greenhouse in Almer• a, Spain, was investigated. Extracted residues were quantiÐed by GC-ECD and their composition veriÐed using GC-MS. Recovery of fenpropathrin from samples spiked with di †ering amounts of the compound were assessed. For statistical purposes, the loss of fenpropathrin with time was considered to follow a pseudo-Ðrst order reaction. The plant species and the season had a signiÐcant a †ect on rates of loss of fenpropathrin but the e †ect of the type of greenhouse and of the applied dose were not signiÐcant.
