Clean Plant Programme: India’s Big Step to Ensure Disease-Free Horticulture

India’s horticulture sector, which contributes significantly to agricultural GDP and rural livelihoods, has long faced a silent but devastating challenge: systemic pathogens in planting materials.

Viruses and other hidden infections spread through seedlings, often going undetected until crops show poor yields, inferior quality, or reduced shelf life. Once established, such infections are difficult — and sometimes impossible — to reverse.

In response, the Union Cabinet, in August 2024, approved the Clean Plant Programme (CPP) under the Ministry of Agriculture & Farmers Welfare. The initiative is designed to deliver high-quality, disease-free planting material to farmers while strengthening diagnostic, regulatory, and research infrastructure.

The National Horticulture Board (NHB) is leading the implementation in collaboration with the Indian Council of Agricultural Research (ICAR), with funding assistance that includes a loan from the Asian Development Bank (ADB).

Why Clean Plant Programme Matters

Horticulture’s Hidden Challenge

Before CPP, farmers largely depended on unregulated nurseries where plant health screening was often weak or inconsistent. Pathogens in mother plants and the lack of advanced diagnostic facilities meant that even healthy-looking seedlings could later fail, reducing yields and increasing production costs. For fruit crops like grapes, citrus, pomegranates, and apples, this created serious risks for growers, exporters, and consumers alike.

The CPP aims to transform this scenario by ensuring systematic production and distribution of certified, pathogen-free planting stock.

Key Features of the Clean Plant Programme

Establishment of Clean Plant Centers

The programme envisions nine Clean Plant Centers across India to supply disease-free planting material. Of these, three major centers are being set up in Maharashtra — Pune (for grapes), Nagpur (for oranges), and Solapur (for pomegranates) — with a combined investment of around ₹300 crore.

Nursery Support and Expansion

To ensure a steady supply of quality seedlings, modern nurseries are being supported with grants:

• Large nurseries: up to ₹3 crore each

• Medium nurseries: up to ₹1.5 crore each

The goal is ambitious — supplying nearly 8 crore disease-free seedlings annually.

National-Level Laboratory in Pune

A dedicated national laboratory in Pune will focus on research related to original plant species and support diagnostic work. Hazard analysis is already in progress, with:

• 578 grapevine samples tested across multiple states

• 535 apple samples studied in temperate zones

• Preparatory work underway for citrus crops

Institutional Strengthening and Technology Integration

Diagnostic Infrastructure

Teams from NHB, ICAR, and ADB have assessed the country’s diagnostic ecosystem, covering public and private laboratories. Their evaluations focus on readiness for high-throughput screening using advanced bioinformatics pipelines, lab oversight, and nursery ecosystem design.

Centralized Digital Platform

A CPP website has been launched to provide updates, resources, and guidance for stakeholders. The implementation framework follows a systematic cycle:

1. Testing planting material

2. Pathogen elimination through tissue culture or similar methods

3. Propagation of clean material

4. Maintenance of mother plants

5. Distribution via certified nurseries

Benefits for Farmers, Consumers, and Trade

Farmers’ Advantage

Adoption of clean, virus-free planting stock will help:

• Improve yields and crop quality

• Enhance fruit shelf life

• Reduce disease-related losses in the early years

• Lower input costs over the long term

Industry and Consumer Gains

Certified nurseries will benefit from stronger trust and more business opportunities. Consumers will access fruits with better taste, appearance, and food safety standards.

Export Competitiveness

Disease-free planting material aligns with international phytosanitary standards, enhancing India’s ability to export horticultural produce globally. This can reduce dependence on imports and strengthen India’s reputation as a reliable exporter.

Challenges and Road Ahead

Despite its promise, the CPP must overcome key challenges:

• Access for small and marginal farmers: Ensuring affordability and timely delivery of clean seedlings.

• Geographic equity: Extending infrastructure to remote or underdeveloped regions.

• Regulatory robustness: Strong certification, monitoring, and biosecurity protocols are critical.

• Mother plant maintenance: Preventing reinfection and ensuring high-quality propagation requires continuous oversight and skilled technical staff.

If addressed effectively, CPP can mark a shift from reactive disease management to preventive, science-driven horticulture systems in India.

Conclusion

The Clean Plant Programme has the potential to revolutionize Indian horticulture by ensuring that farmers plant crops with strong genetic integrity and free of hidden pathogens. By focusing on prevention rather than cure, CPP could increase productivity, stabilize farm incomes, reduce long-term costs, and enhance export competitiveness.

For a sector contributing over 33% of India’s agricultural GDP (2023-24), this preventive push is timely and crucial in making horticulture more resilient to climate change and global market demands.
