Abstract: -The recent introduction of Palmer amaranth (Amaranthus palmeri) in Brazilian agricultural areas may promote several changes on weed management, especially in no-till systems and in glyphosate-resistant crops, since glyphosate-resistant biotypes of A. palmeri have been frequently selected in other countries.

“…In a paper done to verify susceptibility of A. palmeri to glyphosate in Brazil, the same population that was also used in the present paper, Carvalho et al (2015) saw that this is a glyphosate resistant population and it demands dosages above 4,500 g a.e. ha -1 in order to reach DL 80 , which are economically and environmentally unfeasible.…”

“…A. palmeri populations in these areas should be consider resistant to glyphosate and ALS herbicides when planning weed management strategies . A. palmeri resistant to glyphosate and ALS inhibitors was first detected in Brazil in Mato Grosso state 2015, but has been contained so far through cooperative efforts between the Brazilian government and local farmer associations . A 2016 survey of HR weeds in Uruguay found 3500 ha affected by GR A. palmeri…”
