Abstract

The objective of this work was to carry out a technical analysis of the biotechnologies that confer resistance to herbicides in soybeans. Two experiments were carried out (I and II) in the agricultural years 2016/17 and 2017/18, using a randomized block design with six  and four  replicates. In experiment I, two forms of management in weed control were evaluated for each technology studied (Roundup Ready® and Liberty Link®) and for conventional soybeans, as well as grain yield. In experiment II, the efficiency of using different herbicides to control voluntary soybeans (with and without technology) was evaluated. The pre-emergent herbicides in both managements proposed for the cultivars controlled the weeds from the emergence of the soybean crop to the application of the post-emergent herbicides in both crops. Likewise, all post-emergent herbicides showed weed control above 90% at 14 and 28 days after application. In the evaluation of the chemical control of Garra IPRO voluntary soybean, the herbicide 2,4-D stood out among the others for being more efficient in both agricultural years (above 90%). The herbicides glyphosate, 2,4-D and metsulfuron-methyl are the most effective in controlling voluntary soybean cultivars BRS 284 and CZ16B39LL.
