Abstract
The reference studies showed that the farmers of Batticaloa district are using synthetic and cocktailed pesticides in high frequencies and high dosages. In order to evidence that the present study was undertaken in the Batticaloa district. Okra and brinjal are major crops cultivated in the Batticaloa district. A questionnaire survey was conducted by using 1200 farmers (2% of vegetable farmers from each DS Division) to aware of the ways adopted by farmers during the application of pesticides. Results of the questionnaire survey revealed that 90% of the farmers didn’t follow the recommended practices while applying pesticides. Further, they did not get recommendations about pesticides from an appropriate source/center. In addition, Okra and brinjal pod samples were randomly collected from 40 farmer fields and 10 markets in the Batticaloa district to determine pesticide residues by using Gas Chromatograpgy/Mass Spectrometry/Mass Spectrometry (GC/MS/MS). The samples were extracted according to the AOAC official method 2007.01. The presence of pesticide was confirmed by using retention time and mass spectrum. Reported residue levels were compared with EU MRL. Analyzed reports revealed that there were no okra samples contaminated with pesticide residues, which were analyzed during the study period. However, one brinjal sample collected at the Kaluwanchikudy market and 4 brinjal samples of Kaluthavalai farmer fields were contaminated with Profenofos residues. The study recommended that analyze the residue of pesticides which frequently used by farmers including banded and restricted pesticides in Sri Lanka for major cultivating vegetables in the Batticaloa district and expand it into other districts in Sri Lanka.
