Abstract

This study aims to 1) calculating residual insecticide chlorpyrifos active substance in long beans, 2) determine the physical characteristics of the beans, and 3) calculating the correlation between residual insecticide chlorpyrifos active substance and physical characteristics long beans that was sold in Denpasar traditional market. Based on purposive sampling method, 43 long beans seller obtained from 9 subdistrict. Insecticide residues correlated with some physical characteristics of the product moment correlation by using a computer program package Statistical Product and Servise Solution 17.0 for Windows.
