El Salvador bans Roundup and gets record harvest!

1. In September 2013, El Salvador passed a ban on 53 crop protection products for agricultural use. Among them, the large coffee, cotton, maize and sugarcane producing country was pulling off Roundup (glyphosate), a Monsanto star herbicide, recently listed as a "probable carcinogen" by the World Health Organization (WHO).
2. GMO seeds cannot be saved from old crops, they must be purchased every year, leading to an increased cost for the farmers.
3. The GMO seeds were not adapted to the locality. 
4. They are using H-29 maize instead.
