The wash water is distributed over a substrate of soil and straw in a waterproof container 1. Potential product residues are degraded biologically 2. and the clean water evaporates 3. The straw in the Phytobac 4. serves to feed the microorganisms and is stocked up once a year. Once set up, a substrate can be used over many years.
In laboratories of Bayer, scientists develop effective breeding methods for wheat. To achieve this, they perform extremely precise work: For example, the breeders use sterile tweezers to remove stamens from wheat ears. This process ensures that the plants cannot self-pollinate and that they can, therefore, be selectively crossbred.
