Abstract: In Brazil, soybean production has increased with an annual growth of 7.2% since 1996. The adoption of transgenic soybean, rendered tolerant to glyphosate herbicide, has contributed to this remarkable increase. After the presentation of soybean production in Brazil, this article introduces the results of a survey conducted to capture the use of transgenic soybean, during the 200708 campaign in Paraná, one of the main producing States. The survey indicates that producers may show no, partial or total adoption of glyphosate-tolerant varieties of transgenic soybean. The allocation of transgenic soybean to most weedy plots is one reason of the coexistence of transgenic and non-transgenic soybean within the same farm holding. The continuation of the observed coexistence depends particularly on the evolution of royalties on transgenic soybean, and on the measures to ensure the non-transgenic purity of conventional soybean seeds.
