Sensibilidade de biótipos de azevém a glyphosate, iodossulfurom-metílico e clethodim [PDF]

Revista Brasileira de Herbicidas, 2015
O azevém (Lolium multiflorum) é uma gramínea anual, tradicionalmente utilizada como forrageira que se tornou planta daninha em lavouras no sul do Brasil. Tem-se observado biótipos de azevém, resistentes ao glyphosate, sobrevivendo à aplicação de herbicidas inibidores de ALS e ACCase. Assim, objetivou-se avaliar a sensibilidade de diferentes biótipos de
