SAN VICENTE, MISIONES, ARGENTINA – NOVEMBER 2012: Fabian Rodgriguez suffers from hydrocephalus. His mother, Candida Rodriguez, works in the tobacco industry, as does her husband. They use agrochemical products for the cultivation of their fields, following the guidelines set out by the cooperatives of large local producers, who require the use of such agrochemicals as a condition to the purchase of their crop. Among the agrochemicals required are glyphosate and 2.4 D, a product found in Agent Orange. The financial costs of these products always fall on small producers, who only retain 40% of the value of the crop, which is unilaterally fixed by the cooperatives of large producers.
