  • English abstract
  • In the State of Parana in Brazil, the survey we conducted revealed that 21%, 34% and 45% of producers were respectively having no, total and partial adoption of RoundUp Ready soybean (RRS). Coexistence within the same farm holding pertains to various levels of RRS adoption ratio. It indicates a management approach, at least on the part of the producers involved, in using RRS according to weed infestation levels in soybean plots. Continuation of the balanced coexistence depends on various factors, namely the purity of Conventional soybean (CS) seeds with regard to GMO content, Monsanto's strategy on royalties, and increase of the market premium to CS producers.
