EXPLORING PESTICIDE APPLICATION PRACTICES FOR MANAGING PROMINENT AGRICULTURAL PESTS IN AND AROUND TENKASI

This study, conducted between November and March in the Tenkasi district, examined pesticide usage in relation to crop cultivation in Shencottai, Sundarapandiyapuram, Sambavarvadakarai, Panboli, Kadayam, and Surandi. Sunflower, coconut, raw banana, paddy, and potato were the prominently cultivated crops. Pesticides like neem oil, FAME, carbaryl, coragen, malathion, and dimethoate were employed based on specific crops, showcasing diverse pest management strategies. Analysis revealed Dimethoate as the most extensively used pesticide, underscoring its significance in pest management during the study period. The study highlighted the broader ecological impact of pesticides, emphasizing risks to wildlife and plants. Ecotoxicology, focusing on pesticide impacts, was introduced. The study noted the far-reaching effects of pesticides, considering runoff, wind drift, and the persistence of certain pesticides like DDT and chlordane. Plants' absorption of pesticides through roots and leaves indicated their susceptibility. The cumulative impact on individual plants and animals underscored the need to address potential ecological consequences. In the study urged a careful evaluation of pesticide usage, considering environmental impacts. Adhering to label instructions and exploring alternatives with lower toxicity was advised. Integrated pest management (IPM) and proactive measures to prevent contamination in crucial locations were recommended. The study proposed organic farming as a sustainable alternative, contributing to a healthy environment and human well-being.
