A radio program about a conspiracy theory

In Recently I listened to an online radio program about a conspiracy theory. It is was an episode content about the a Sustainable Agriculture Company. These presides discuss It showed that the company have had made GM(Genetically modified) seeds and bought sold them to farmers. They said it is the GM seeds will grow to into non seedless plants. So these farmers will be would need to buying seeds on next each season, and furthermore in the field where they had planted that the GM seeds, there  do not they cannot plant other seeds. because it is has already changed the field material soil. Therefore these farmers need to trade with this company in the future. The prices and quality was were under the control at of the company.
