Conscious of the constant reduction in the number of products available to farmers and growers, Certis has been diligent in its efforts to advocate careful stewardship of products. This has involved the use of monitoring systems to guide decisions about product usage and the development of optimum application methods to help protect the environment, workers and neighbours to help ensure the sustainability of products.
