Mancozeb Residue on Tomatoes in Central Uganda.

Background: Mancozeb belongs to a group of pesticides known as dithiocarbamates (DTC) that are a non-systemic group of pesticides extensively used in Uganda to protect crops from fungal diseases.

Objectives: This study was done in 5 selected districts of Central Uganda with a focus on markets and farms to investigate the current mancozeb concentrations on tomatoes and identify key areas of improvement to minimize human exposure.

Methods: Tomato samples were analyzed for mancozeb residue determined as carbon disulfide (CS) by gas chromatography-mass spectrometer (GC-MS).
