Pesticide residue analysis of “Pinakbet type” vegetables in the municipality of Lal-Lo, Cagayan
Abstract
The study was conducted among the pre-identified major vegetable producing barangays in the Municipality of Lal-lo. It aims to determine the management practices of vegetable producers, the most common pesticides used, the level of pesticide residue, conformity of pesticide residue to ASEAN’s MRL, conformity of farmers practices to the pre-harvest interval (PHI) practices and to Geo-tag vegetable farms producing vegetables with positive detection to pesticide residue. Data were gathered through interview with questionnaire to the farmers. The information gathered includes production techniques, crop management practices, and marketing strategy. Vegetable sampling was done on-farm and on commercial market for the pesticide residue analysis. Analysis was conducted at Cagayan Valley Integrated Agricultural Laboratory (CVIAL) and Cagayan State University at Lal-lo using Rapid Test Kit. Lastly, Geo-tagging was done using Global Positioning System (GPS) application. Based on the results, most farmers practice mono-cropping in vegetable production with pesticide chemicals being used in managing pest infestation. Application of the chemical was done early in the morning and late in the afternoon with a frequency of twice a week and every after harvest. The most commonly used pesticide were malathion, lannate and magnum. Furthermore, results of pesticide residue analysis showed that most vegetable samples taken from public market and on-farm had positive detection both in carbamates and organophosphate test. The concentration level of pesticide residue is higher than the Association of South East Asian Nation on Maximum Residue Level/Limit (ASEAN MRL).
