This article presents four years of field research into the commercialisation of genetically modified Bt cotton in Andhra Pradesh, India.

The author, Glenn Stone, challenges the assumption that the rapid spread of Bt cotton is due to farmers carefully assessing the technology on a small scale before adopting it more widely.

Instead, Stone likens the process to a "craze", arguing that Bt cotton technology has disrupted farmers' learning process, as they rely less on experimentation and observation and more on advertising and copying their neighbours.

The article includes critical commentaries by leading scholars from Europe and the United States.
