Pam Marrone is energetic, innovative and frustrated. She’s the founder and background force for Marrone Bio Innovations, a Davis, Calif., firm that has been a trendsetter in a growing area of technology: biologicals. And why is Marrone frustrated? Because environmentalists and regulators start talking about banning a traditional crop protection product, but never consider ways to bring alternatives to work on the issues, she says. For example, there’s talk of banning chlorpyrifos in crops.
