According to The Organic and Non-GMO Report, April 2010 :

At least seven US state attorneys general are investigating whether Monsanto Company has abused its market power to lock out competitors and raise prices on seed. Iowa, Illinois, Ohio, Texas, Virginia, and two other unidentified states are in a working group to investigate the biotech giant.

The states are probing whether Monsanto violated laws by offering rebates to seed distributors for excluding rival seeds, imposing limits on combining the product with other genetic modifications, or offering cash incentives to switch farmers to more expensive generation of seed varieties.

The state investigations add to pressure on Monsanto. The US Justice Department is investigating the company’s marketing practices, and DuPont Company has accused Monsanto of anti-competitive practices in licensing litigation.

And Monsanto’s stock price is down more than 30%, from $93.35 in May to a 52 week low of $63.75 Friday.

Interesting developments.
