What Plant Health Care does

Plant Health Care plc is a UK-incorporated agricultural biological products company that develops and commercializes proprietary peptide- and protein-based crop inputs under two technology pillars: the patented Harpin αβ recombinant protein (sold globally as ProAct, H2Copla, Inceptive and Messenger) and the newer PREtec (Plant Response Elicitor) peptide platform, which spans the Innatus 3G disease-control family (commercialized as Saori in Brazil from 2021 and Obrona in the US from 2023) and the T-Rex 3G bionematicide family (commercialized as Teikko in Brazil from 2024). The company's products activate plants' natural defence and stress-response pathways rather than acting as direct pesticides, are classified by the US EPA as low-toxicity with zero residues, and are supported by an in-house Seattle pilot fermentation facility capable of producing approximately 100 kg of peptide per month, with commercial manufacture scaled to 5,000-litre fermentation through third-party producers. The portfolio also includes the Myconate family of mycorrhizal fungi promoters and a pipeline (including PHC68949) targeting a stated addressable market exceeding USD 5 billion across three PREtec products.

Plant Health Care generates revenue primarily through one-time B2B product sales to specialist agricultural distributors and direct sales via wholly owned subsidiaries in the UK, Spain, Mexico, Brazil and the USA; its Mexico subsidiary additionally distributes third-party biological products, generating distribution margin on complementary inputs. The commercial model is hybrid channel: exclusive and core distribution agreements with major industry partners including Nutrien (Brazil), Wilbur-Ellis (USA), Coplacana (São Paulo sugarcane), DuxAgri (22 sub-Saharan African countries), EDAF (Portugal), Talc U.S.A. (US corn) and AMVAC (China), supported by co-branded product launches such as H2Copla and Inceptive. End-customers are row-crop growers (soybeans, sugarcane, corn), specialty fruit and vegetable producers, and turf/ornamentals managers, with quantified field outcomes including up to 12% sugarcane yield uplift for H2Copla and up to 15% yield improvement for PREtec seed treatments.

Plant Health Care was AIM-listed in London from July 2004 under ticker PHC until 20 August 2024, when it was acquired by India's PI Industries Ltd and became a wholly owned subsidiary; in November 2025 PI Industries rebranded the business as PI AgSciences, its global agricultural arm. The company was historically funded through a combination of AIM share placings and post-IPO equity (approximately USD 10 million in 2021 and GBP 2.8 million in June 2023) against an aspirational USD 30 million revenue target for 2025, and operates with 101–250 employees across its subsidiaries.

Revenue model

1. Commercial Product Sales (Harpin αβ brands and PREtec peptide products): Sales of proprietary biological products (Harpinαβ, ProAct, Myconate, Saori, Obrona, Teikko and other branded products) to specialist distributors globally and direct through operating subsidiaries; sold via one-time product purchases by agricultural distributors and growers.
2. Distribution of Third-Party Biological Products (Mexico): In Mexico, the Group also distributes third-party biological products, generating distribution/mark-up revenue on complementary biological inputs alongside its own PHC branded range.
3. Equity Funding (Share Placings/Subscriptions): Historically raised growth capital via share placings and subscriptions on AIM (e.g., GBP 2.8 million raise in 2023 and a prior USD 10 million raise) to fund new product launches, inventory expansion and accelerated commercialization; aspirational revenue target of USD 30 million by 2025.

Core offering

Plant Health Care develops and sells proprietary agricultural biological products built on two technology pillars: the Harpin αβ recombinant protein (marketed globally as ProAct, H2Copla, Inceptive and Messenger) and the PREtec (Plant Response Elicitor) peptide platform, which includes Innatus 3G and T-Rex 3G families commercialized as Saori, Obrona and Teikko. Products are biostimulants, biofungicides and bionematicides that activate plants' natural defense and metabolic systems to improve yield, quality and stress tolerance, sold B2B through specialist distributors and direct subsidiaries in the UK, Spain, Mexico, Brazil and the USA.

Product overview

Plant Health Care offers a portfolio of proprietary agricultural biological products and technology solutions built on two main technology pillars: (1) the Harpin αβ recombinant protein, marketed globally under multiple brand names (ProAct, Messenger, H2Copla, Inceptive), and (2) the PREtec (Plant Response Elicitor Technology) peptide platform, which houses two peptide families — Innatus 3G (disease control, commercialized as PHC279/Saori in Brazil 2021 and Obrona in the US 2023) and T-Rex 3G (nematode control, commercialized as PHC949/Teikko in Brazil 2024). Other commercial offerings include the Myconate family (Myconate AS, Myconate HB) of mycorrhizal fungi promoters and the PREzym biostimulant. Following the August 2024 acquisition by PI Industries Ltd., Plant Health Care operates as a wholly owned subsidiary rebranded as PI AgSciences in November 2025. Plant Health Care does not sell a single unified software product — its offerings are a platform-plus-modules architecture spanning peptide active ingredients, branded end-products, regional distributor relationships, and subsidiaries in the UK, Spain, Mexico, and Brazil.

Direct peers

• Novonesis (formerly Novozymes): Global leader in industrial enzymes and microbial biological solutions for agriculture; comparable as a direct peer in agricultural biologicals/biostimulants with comparable B2B distributor-led go-to-market and overlapping crop input categories such as yield enhancement and disease management.
• Valent BioSciences: Specialist subsidiary of Sumitomo Chemical focused on biorational products (biostimulants, biopesticides, inoculants) for crop protection and yield; highly comparable as a direct peer in proprietary biologicals with similar crop segments (row crops, specialty fruits and vegetables) and global distribution model.
• Koppert Biological Systems: Dutch specialist in biological crop protection and natural pollination with biostimulant and biopesticide portfolios; comparable as a direct peer in sustainable agricultural biologicals serving specialty and row crops globally with strong distributor networks.

Broad incumbents

• Syngenta Group: Global agrochemical and seed major with a dedicated biologicals platform; comparable as a broad incumbent targeting the same row-crop and specialty-crop growers with overlapping biostimulant and biocontrol product lines, but with vastly greater distribution scale and R&D budget.
• Bayer Crop Science: One of the largest crop protection and seed companies, with a growing biologicals portfolio through its Biologics by Bayer group; comparable as a broad incumbent that overlaps with PHC's biostimulant/biopesticide/nematicide categories but operates at much greater scale across a full chemistry-and-seed portfolio.
• BASF Agricultural Solutions: Global agrochemical major with a biological crop protection and seed treatment portfolio; comparable as a broad incumbent operating in biostimulants, biological seed treatments and biocontrol categories that overlap with PHC's peptide and mycorrhizal offerings.
• Corteva Agriscience: Global seed and crop protection major with an expanding biologicals business (e.g., biologicals acquisitions and partnerships); comparable as a broad incumbent offering overlapping biological and biostimulant solutions alongside a much larger conventional chemistry portfolio.

Others

• PI Industries Ltd: Indian agrochemical parent company that acquired Plant Health Care in August 2024 and now operates it as PI AgSciences; included as an adjacent/parent comparator since it represents the ultimate owner and provides context on PHC's positioning within a larger sustainable crop solutions portfolio.

Emerging players

• Pivot Bio: US-based agtech company commercializing microbial nitrogen-fixing products for row crops (corn, sorghum, wheat); comparable as an emerging player in agricultural biologicals with comparable distributor-led model and a focus on replacing/reducing synthetic inputs such as fertilizer.
• AgBiome: US-based biologicals company developing microbial crop protection and crop nutrition products; comparable as an emerging player focused on biological disease and pest control with similar go-to-market through distributors and direct sales in row and specialty crops.
