I’ve heard of Terminator Seed. Remember it was really bad, but the specifics I’m fuzzy about. I think it might include, crossbreeds with other seeds, making them sterile? Requiring everyone to buy seed every year. And they were trying to push this seed in Africa?
Yep, one time use seeds meaning if the farmer cannot purchase seeds the next growing season they are in a bad way as they have no seed in reserve to grow a crop the next season.
So a flood, a drought, what have you, and the farmer is wiped out.
