A Decision Support System for Sustainable Pesticide Management in Brinjal Production

Abstract

Brinjal (Solanum melongena) is a major vegetable crop in Pune, extensively cultivated for both consumption and earnings. Farmers generally control pests like the shoot and fruit borer using chemical pesticides, which are applied in excess of recommended doses. This study examines the effect of pesticide application on brinjal yield, fruit quality, pesticide residues, ecological balance, and farmer practices. Field surveys were carried out at 20–30 brinjal farms on an integration of crop sampling, GC/LC-MS residue analysis, ecological evaluation of beneficial insects, and formal Knowledge–Attitude–Practice (KAP) questionnaires from farmers. Outcomes indicated that although intense pesticide application moderately enhanced yield, it did not regularly enhance quality in fruit. Residues were present in every sample with 10% above Maximum Residue Limits (MRLs). Beneficial insect populations were reduced significantly in highly sprayed fields, reflecting ecological disruption. KAP surveys showed farmers knew of pesticide hazards but poorly practiced safety measures. The research emphasizes the importance of adopting Integrated Pest Management (IPM), safe use of pesticides, and training farmers. Findings add region-specific knowledge to sustainable brinjal production and advise minimizing environment and public health hazards.
