dc.description.abstractThe emergence of Mucuna species in sugarcane plantations, even after herbicide spraying for weed management, allowed us to elaborate the hypothesis that these plants are tolerant to the herbicides commonly used in the culture. Thus, to prove this hypothesis, this work was carried out to study the tolerance of Mucuna aterrima, Mucuna cinerea and Mucuna deeringiana to application of herbicides with different mechanisms of action in pre- and postemergence. The experiment was arranged in a randomized block design with 9 treatments and five replications in a factorial 3 × 3, plus controls. At pre-emergence, the first factor was constituted by the herbicides sulfentrazone (800 g ha-1), imazapic (245 g ha-1), and amicarbazone (1,400 g ha-1), and the second factor by the Mucuna species, besides the additional control for each species studied. At post- emergence, the herbicides tested were clomazone (1,100 g ha-1), ametryn+trifloxysulfuronsodium (1,463 + 37 g ha-1), and 2,4-D (1,209 g ha-1). In the chemical management at pre-emergence, the species were sensitive to amicarbazone, followed by sulfentrazone, and tolerant to imazapic. At post-emergence, all species were sensitive to ametryn + trifloxysulfuron-sodium and 2,4-D, but tolerant to clomazone.en
