Herbicide resistance technologies in soybean cultivars

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