In its constant pursuit of advanced technologies for agriculture, in 2017 DIACHEM acquired PIRECO Productie B.V., a Dutch company based in Lelystad specialized in the research and production of natural biostimulants and plant extract-based products with “zero” environmental impact. With Pireco, Diachem has started to pursue the path of ecological and sustainable solutions for a wide range of crop pests and other issues of conventional and organic agriculture and horticulture.
