Abstract

Enhanced selectivity can be achieved for some herbicide treatments through the application of chemicals that reduce or protect plants from injuries. The objective of this work was to evaluate the potential to prevent herbicide yield losses in glyphosate-resistant soybean by the use of the biostimulant Fertiactyl PÓS. Based on results from two field experiments, the association of Fertiactyl PÓS with glyphosate applied post emergence of soybeans reduced foliar injuries and prevented yield losses caused by the herbicide, either when glyphosate was applied in one single application or when it was applied in two sequential applications. However, the application of the Fertiactyl PÓS was not enough to assuage the injuries caused by the mixtures of glyphosate+lactofen and glyphosate+chlorimuron-ethyl.

Key words: Glycine max, mitigation, selectivity.
