The webinar examined the fungicide’s scientific attributes, its integration into disease management programs, regulatory trends, and its broader implications for farm profitability and food security. 

The virtually held discussions underscored that fungicide stewardship is no longer merely a technical matter; it is intricately linked to growers’ livelihoods, market access, and global food stability.

 Economic Lessons from Disease Modeling

The session commenced with a presentation by Dr Kaushik Banerjee, FRSC, FNAAS, Director of ICAR-NRC for Grapes and Honorary Professor at Queen’s University Belfast and the University of Laval, Canada. Dr Banerjee framed the discussion by highlighting the economic and systemic impacts of grape disease outbreaks.

Using advanced agronomic modeling, he demonstrated that fungal infections, particularly under high-pressure disease scenarios, can trigger cascading effects on farm profitability, regional supply chains, and even international markets. His analysis emphasised that targeted fungicide programs, including those employing Mancozeb, are not merely preventive measures at the field level but essential tools for stabilising grower income and maintaining global food security.

“Every outbreak of grape disease is not just a threat to individual farms—it sends shockwaves through regional supply chains, export markets, and farmer livelihoods. Strategic fungicide programs, including judicious use of Mancozeb, are critical investments. Timely, science-driven interventions safeguard yields, stabilize income, and ensure that agriculture continues to feed both people and economies sustainably.”

Dr Banerjee illustrated that under certain high-incidence conditions, the absence of an effective fungicide program could result in yield losses exceeding 30 to 40 percent, with downstream effects on pricing, processing capacity, and export viability. He stressed that investments in fungicide programs, though an upfront cost, are economically justified when considering the potential revenue losses avoided and the risk mitigation achieved.

 Ensuring Safe Access to Mancozeb Worldwide

Following Dr Banerjee’s presentation, the discussion shifted to regulatory science and risk assessment. Richard Mills, Global Director of Trade and Government Affairs at UPL, provided a comprehensive overview of the evolving global regulatory landscape for fungicides.

Mills articulated the distinction between risk-based and hazard-based regulatory frameworks, emphasising that risk-based assessments evaluate the probability and impact of exposure under realistic use conditions, whereas hazard-based approaches may restrict chemicals based solely on intrinsic properties without contextual application data. He further elaborated on the importance of personal protective equipment compliance, residue monitoring, and data-driven stewardship programs to maintain both domestic and international access to Mancozeb.

“Regulatory frameworks are only as effective as the practices behind them. Risk-based assessments let us evaluate real-world exposure, while hazard-based approaches can be overly restrictive. By combining compliance, PPE, residue monitoring, and proactive stewardship, we ensure safe, responsible use of Mancozeb, protecting both public health and growers’ market access across diverse international jurisdictions.”

Mills highlighted that harmonizing regulatory compliance across countries is essential for exporters, as maximum residue limits (MRLs) vary widely across jurisdictions. He stressed that proactive engagement with regulators, transparent record-keeping, and adherence to recommended application practices are vital to safeguarding market access while ensuring public safety.

 How Tech is Revolutionising Disease Control

Building upon the regulatory perspective, Sandeep Jagtap, Senior Business Development Manager at Ross LifeScience, addressed the integration of Mancozeb into Integrated Pest Management (IPM) strategies and the role of digital agriculture.

Jagtap elaborated on how precision tools, including digital disease forecasting models, remote monitoring platforms, and app-based advisory services, allow growers to optimise fungicide use, ensuring applications are timely and necessary, thereby minimizing both economic and environmental costs. He underscored that combining chemical interventions with cultural practices such as canopy management, crop rotation, and resistant varieties enhances the sustainability and effectiveness of disease control programs.

“Integrating Mancozeb into IPM isn’t just about spraying—it’s about precision, timing, and sustainability. Digital tools like disease forecasting and remote monitoring help growers apply fungicides only when necessary, reducing costs and environmental impact. When combined with cultural practices like canopy management and resistant varieties, these strategies optimize yield, protect the ecosystem, and make viticulture smarter for every scale of farming.”

By demonstrating case studies where digital tools helped reduce fungicide usage without compromising yield, Jagtap highlighted that technology adoption in viticulture can be scaled to support both large commercial growers and smaller farmers, providing actionable insights that translate into improved farm profitability and environmental stewardship.

  Collaborative Approaches to Fungicide Stewardship

Concluding the speaker presentations, Amiya Kumar Bartia, Strategic Marketing Head at Indofil, shared the industry’s perspective on stewardship and sustainable crop protection strategies.

Bartia emphasized that ensuring responsible access to Mancozeb requires multi-level collaboration among growers, industry stakeholders, and regulators. He described initiatives such as educational outreach programs, grower training sessions, and digital monitoring tools that reinforce proper application practices and adherence to safety protocols.

“Responsible access to Mancozeb demands collaboration across growers, industry, and regulators. Stewardship isn’t just compliance—it’s a strategic imperative. Through training, outreach, and digital monitoring, we ensure safe, effective application while safeguarding market continuity. By building trust and engagement, we balance crop protection, environmental responsibility, and social accountability, promoting sustainable practices in high-value horticulture.”
