Our innovative, patent-protected biological products help growers to protect their crops from stress and diseases, and to produce higher quality fruit and vegetables in an environmentally sustainable manner while maintaining compatibility with mainstream agricultural practices.


Plant Health Care’s Commercial business is driven by sales of Harpinαβ, a recombinant protein which acts as a powerful biostimulant, promoting the yield and quality of crops, and PHC279, a novel harpin-derived peptide that amplifies a plant’s natural defense against a range of diseases, increasing plant health and yield. A number of our important brands are shown below.

Cost-effective products for sustainable agriculture

  • Harpinαβ is sold as H2Copla into sugar cane in Brazil, through Coplacana, the largest distributor of inputs for this crop. Sales in Brazil sugarcane continued to grow under challenging conditions throughout 2023, up 45% compared to 2022. Overall, our Brazil business was up 42%
  • The Group received registration for Harpinαβ in Argentina for use in corn and soybeans in August 2021 with first year sales through our partner TROPFEN S.A. occurring in the 2022 cropping season.

  • In North America, total revenue was down 45%. The decline was primarily due to the impact of an exceptional destocking by US distributors to reduce the impact of price volatility in an uncertain market. Higher interest rates prompted distributors and farmers to lower their inventories to manage their working capital.
  • Having received an expanded California label for our Employ product in early 2024, we expect strong performance in fruits, nuts, vegetables and row crops through Wilbur-Ellis and our pre-plant seed treatment for corn (Fastand®) through the second largest distributor in the US.
  • In corn, farmers apply Fastand to the seed prior to planting; the crop comes up stronger and taller and better able to resist stress such as drought. Higher yields result.
  • 2024 will be the first full season of sales for the Obrona biofungicide and we expect Obrona to provide significant revenue over the coming years.
            • In Spain, the UK and parts of Europe, Harpinαβ is sold as ProAct AA and under other brands, where sales into fruit, vegetables crops and turf reached $1.5 million in 2023.
            • In the UK, Harpinαβ is sold through Headland, a major distributor supplying to the professional turf market. Many leading golf courses and football fields are greener and more resilient to abiotic stress as a result.

            • Plant Health Care Mexico employs a staff of 16, including sales and technical specialists in the field, selling to retailers throughout the country.
            • With the recent registration approval of PHC279 for disease control and PHC949 for nematode control we expect a significant shift in revenue to these proprietary products resulting in greater revenue and higher margins.
