Bayer CropScience Inc..

Bayer CropScience's origins trace back to the 1863 founding of Bayer, originally a dyestuffs producer. The company later expanded into pharmaceuticals, including the development of Aspirin. Bayer's entry into crop protection occurred with the 2001 acquisition of Aventis CropScience, leading to the establishment of Bayer CropScience AG in 2002 as a legally independent subgroup.
