Vegetable Protection
Dr. Arvind Nath Singh
Principal Scientist & Head
Division of Vegetable Protection
The Division is committed to safeguarding vegetable crops through development of eco-friendly, sustainable solutions for pest, disease, and nematode management that ensure safe and residue-free produce for consumers. The Division operates a comprehensive research portfolio of 6 Institute and 8 externally funded projects addressing integrated pest management, pathogen diagnostics and characterization, nematode biocontrol, pesticide residue dynamics, and fungicide resistance monitoring.
Research Focus
Central to all research activities is the guiding principle of reducing chemical pesticide dependency while sustaining crop productivity through bio-intensive and knowledge-based approaches, directly supporting India’s ‘Natural Farming Mission’ and ‘Atmanirbhar Bharat’ vision.
The Division has identified effective newer molecules and integrated modules for managing sucking pests, lepidopterans, and mite complexes in key vegetables while conserving beneficial natural enemy populations. Crop-specific IPDM modules validated in cabbage and cowpea have achieved substantial pest suppression while maintaining pollinator safety and natural enemy conservation.
Pathogen & Pest Characterization
Molecular characterization of important fungal pathogens including Alternaria and Diaporthe species has been accomplished with sequences deposited in international repositories. Indigenous biocontrol agents, particularly Trichoderma asperellum and rhizobacterial strains, have demonstrated remarkable efficacy against root-knot nematodes under field conditions.
Innovative environmental remediation approaches using invasive weed-derived biochar have shown exceptional capacity for removing pesticide residues from contaminated soils.
Pesticide Residue & Food Safety
Dissipation kinetics and waiting periods have been established for commonly used insecticides. Simple household decontamination methods using sodium bicarbonate have been standardized for removing pesticide residues from market vegetables, enhancing consumer safety and public health.
Impact & Stakeholders
Farmers gain access to cost-effective, environmentally sound pest management strategies producing safer vegetables with better market acceptance. The scientific community benefits from well-characterized pathogen and pest isolates, standardized screening protocols, and validated residue analytical methodologies.
Agri-industries leverage bioformulation technologies and multi-residue testing capabilities for product development and quality assurance. Policy makers receive scientific evidence supporting MRL compliance frameworks, pollinator protection guidelines, and export-quality standards—collectively strengthening India’s credibility in international vegetable trade.
