North America (Corn)

  • Harpin αβ is sold into corn through the second largest distributor in the USA. Farmers apply Harpin αβ 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.

Sales of Harpin αβ increased 142% to 157,000 ounces in 2021 due to increased sales into the California almond and grape markets. In-market sales into the fruits and vegetable markets since 2019 have grown at 116% CAGR.
  • In Spain, Harpin αβ is sold as ProAct AA, where sales into fruit and vegetable crops have now reached $1.2 million.
  • Sales growth in Spain was driven by Harpin αβ sales into citrus and expansion into the greenhouse market.
  • In the UK, Harpin αβ 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.
  • The Group signed an exclusive Harpin αβ distribution agreement with UK market leader Agrii in July 2021.
  • Plant Health Care Mexico sells a range of sustainable products to farmers in Mexico. Harpin αβ represented 23% of sales in 2021, with third-party products making up the remainder.

  • Sales in Mexico were held back in 2021 due to decreased domestic demand for fruits and vegetables and reduced plantings in Baja California due to adverse weather conditions.
