Abstract

The use of pesticides for pest control is a common practice in agricultural production systems of Nicaragua. In this study 21 pesticides (7 organophosphorus insecticides, 1 organochlorine insecticide, 3 pyrethroid insecticides, 7 herbicides and 3 fungicides) were studied and determined in samples of tomatoes, peppers, lettuce and cabbage collected in 2 popular markets and 2 supermarkets of Managua. The analysis reflects that 55,0% of the samples contain pesticides, managing to identify residues of chlorpyrifos, mocap, cypermethrin, chlorothalonil, imazalil, diazinon, deltamethrin, simazine and 2,4-D, in concentrations between 0,005 mg/kg up to 5,3 mg/kg.  20,0% of the samples contain residual variables that exceed the values established in the Codex Alimentarius in the matrices lettuce (diazinon), cabbage (chlorpyrifos and diazinon), tomato (mocap and deltamethrin).
