Em casa de vegetação, o delineamento foi o completamente casualizado, com 21 tratamentos compostos pela aplicação de clodinafop (0, 3, 6, 12, 24, 48 e 96 g ha-1) isolado ou em mistura com metsulfuron-methyl (2 e 4 g ha-1) ou 2,4-D (470 g ha-1). Em campo, o delineamento foi de blocos casualizados, com 12 tratamentos, arranjados em fatorial 6 x 2, composto pelos níveis de clodinafop-propargyl (0, 3, 6, 12, 24, 48 e 96 g ha¹) isolado ou em mistura com metsulfuron-methyl (2 g ha-1). A avaliação visual de controle, em casa de vegetação, revelou I50 das misturas de clodinafop-propargyl + metsulfuron-methyl (2 e 4 g ha-1) ou clodinafop-propargyl + 2,4-D (470 g ha-1), respectivamente, 33, 84 e 151% superiores ao de clodinafop-propargyl isolado. Já para matéria verde de azevém, o I50 das misturas supracitadas foi, respectivamente, 119, 244 e 72% superior ao de clodinafop-propargyl isolado.

In the greenhouse experiment, 21 treatments were tested, composed by clodynafop(0, 3, 6, 12, 24, 48 and 96 g ha-1) alone or tank-mixed with metsulfuron (2 and 4 g ha-1) or 2,4-D (470 g ha-1). In the field experiment, twelve treatments were set up in a factorial 6 x 2, composed by clodinafop (0, 3, 6, 12, 24, 48 and 96 g ha-1) alone or tank-mixed with metsulfuron (2 g ha-1). In the greenhouse experiment, the control (visual evaluation), I50 from the mixtures with metsulfuron (2 and 4 g ha-1) or 2,4-D (470 g ha-1) were 33, 84 and 151% higher than clodinafop applied alone. The I50 from the rye live matter from the mixtures cited above were, respectively, 119, 244 and 72% higher than clodinafop applied alone. In the field experiment, rye live matter reduction was observed with increase of the levels of clodinafop applied alone, but rye live matter did not decrease, changing the levels of clodinafop tank-mixed with metsulfuron. The results reveal the antagonistic effect of tank-mixtures of clodinafop and metsulfuron or 2,4-D.
