Biotech giant Aventis is expected to reveal today that it is in exclusive talks with German firm Bayer over the sale of its Aventis CropScience operations.


The French/German group has been trying to sell the business for some time now but only decided on a valuation last months, when it slapped on a price tag of around US$3bn.


Market watchers may also hear today whether Germany’s Schering, which owns a minority stake in CropScience, has decided to sell and participate in the talks.
