“…However, it was found that the control effect of the mixtures haloxyfop + 2,4-D was slower than the individual applications of haloxyfop or mixtures with fluroxypyr form, and less effective than the control applied at V 5 . Trezzi et al (2007) observed the antagonistic effect of mixing clonadifoppropargyl + 2,4-D (20 670 g ha -1 ) in control of ryegrass (Lolium mutiflorum) regarding the application of the graminicide isolated, as well as higher rates of control with the mixture as the clonadifop-propargyl concentration was increased. As to Velloso & Dal'piaz (1982), they reported the existence of incompatibility mixture diclofop + dicamba + 2,4-D (720 + 576 + 97 g ha -1 ) used in the control of ryegrass (Lolium mutiflorum) and Gorga (Spergula arvensis) on wheat, barley and rye.…”

-The loss of grains during the harvest of glyphosate tolerant corn may generate volunteer plants, which can interfere in the conventional or glyphosate crop in succession. The current work aim to evaluate the control of the volunteer corn glyphosate tolerant under two weed stages. Aimed to evaluate the control of volunteer glyphosate tolerant corn in two stages of development. There were conducted two experiments with hybrid 2B688 HR (lepidoptera and glyphosate tolerant), the application were at V 5 and V 8 stage. The experiment was randomized block design with four replicates, using the treatments: haloxyfop at 25, 50 and 62 g ha -1 alone and associated with 2,4-D at 670 g ha -1 or fluroxypyr at 200 g ha -1 . The standard was clethodim at 84 g ha -1 with 2,4-D and fluroxypyr at same rates. The applications of haloxyfop and clethodim both isolated or in a mixture with 2,4-D and fluroxypyr at V 5 stage showed total control (100%) at 32 and 39 days after the application, except for haloxyfop + 2,4-D (25 + 670 g ha -1 ) mixture, which did not provided adequate control.

“…According Trezzi et al (2007), antagonistic effect of 2,4-D may occur on the graminicides ACCase inhibitors action. Consequently, it becomes necessary to evaluate mixtures and formulations that reduce this effect.…”

“…Associations which result in synergism arouse interest as they allow to improve control or the use of lower doses, which represents production costs reduction. Instead, associations that produce antagonism can result in hindering herbicides performance, requiring dose increase, leading to higher production costs or requiring herbicide application separately (Kruse et al, 2001;Trezzi et al, 2007).…”

-This study was conducted to evaluate the efficacy of joyweed (Alternanthera tenella) control and antagonistic or synergistic potentials of saflufenacil herbicide applied alone or tank mixed with paraquat, metribuzin and clomazone. The experiment was conducted in a greenhouse in a completely randomized design with four replications. Treatments consisted of saflufenacil herbicide doses (0, 0.4, 0.7, 1.4, 2.1 and 2.8 g ha -1 ) applied isolated or associated with paraquat (0, 1 and 3 g ha -1 ), metribuzin (0, 38.4 and 105.6 g ha -1 ) or clomazone (0, 288 and 504 g ha -1 ). Visual control was determined at 14 and 21 days after spraying the herbicides (DAA) and shoots dry matter at 21 DAA. Colby's method was used to calculate the response from herbicide interactions. Saflufenacil associations with paraquat and metribuzin were promising to control A. tenella, due to the high levels of control achieved and because they demonstrated compatibility, especially in some combinations. Tank mixing saflufenacil with clomazone was not promising for the control of A. tenella due to the low efficacy of joyweed control and because it demonstrated herbicide incompatibility.Keywords: Alternanthera tenella, tank mixture, protox inhibitors, photosystem I inhibitors, photosystem II inhibitors, carotenoids synthesis inhibitors.

O experimento foi realizado em vasos, em casa de vegetação, em delineamento inteiramente casualizado com quatro repetições. Os tratamentos foram constituídos de doses do herbicida saflufenacil

“…O manejo de plantas daninhas é ainda mais complexo quando numa mesma área há infestação de plantas daninhas monocotiledôneas (folha estreitas) e eudicotiledôneas (folhas largas) resistentes e/ou tolerantes a herbicidas, ou ainda, plantas em diferentes estádios fenológicos. Nesses casos, há necessidade do uso de herbicidas de diferentes mecanismos de ação utilizados em mistura ou sequencial para controle um efetivo (TREZZI et al, 2007;ZOBIOLE et al, 2016).…”
