plans to integrate ACS with its own Crop Protection Business Group, creating a new company to be known as Bayer Crop Science.
Bayer's New Zealand subsidiary, Bayer New Zealand, supplies a variety of products, including crop protection and animal health products, pharmaceuticals, plastics and speciality chemicals.
Bayer New Zealand's business manager of crop protection, Phil McSweeney, said the acquisition could mean expansion in the crop division's products and services.
