Recently,one of the most indispensable methods has beenthe usage ofimidacloprid(Konfedor® ) and Abamectin (Vertimk®) in crops, which made great improvements towards crops such as tomatoes, cucumbers and peppers. On the other hand there are disadvantages demerits of using such pesticides toward the human health. In this study, two types of pesticides were chosen:imidacloprid and abamectin, for many reasons.First of all they are the most commonlyused among farmers in Palestine, second, these pesticides are the most effective in destroying spiders and many insects. Imidaclopridand abamectin(Vertimk®) where sprayed on tomato, cucumber and pepper crops in three greenhouses using the same concentration that farmers used to spray their crops, with a concentration of 14.5mg /L for imidaclopridand a concentration of 29 mg /L for abamectin.The residues showed that bothimidacloprid and abamectin were higher in quantity than those of residues determined by previous researchers. Also, results obtained from this study showed that the quantities of residues were higher than the maximum residue levels (MRLs) in the samples that were collected on the first, the fifth and the tenth day of spraying. Furthermore, this study showed that the residues of abamectin are higher than imidacloprid, and residues of both abamectin and imidacloprid are higher in soil than in plant parts.The rate of degradation for both pesticides followed the first order with more than 0.97 fitting correlation.
