India finds it difficult to suffice the requirements of ever growing population and use of pesticides in vegetables has increased several folds within the last several years. In tropical conditions, fruits and vegetables are grown throughout the year and cauliflower is very nutritious and fibrous, helps in scavenging free radicals from the body to stop incurable diseases. Vegetable samples of cauliflower collected from Ramanagara district and subjected to gas chromatography equipped with ECD and FTD. Recovery studies performed at fortification levels of 1.0, 0.5 and 0.01 mg/kg and therefore the average recovery rates ranged from 77.3 to 94.7 %. Variation in acephate, chlorpyriphos, dichlorvos, monocrotophos, phorate, cyfluthrin-β, cyhalothrin-λ, cypermethrin, deltamethrin and fenvalerate residues in cauliflower samples is recorded. It is found that 12.5 % of samples from Ramanagara district were having phorate residue value above the MRL of 0.05mg/kg. Pesticides though present in cauliflower sample in Ramanagara district and not exceeded the MRL
