abstract = "After detection of glyphosate-resistant biotypes of sourgrass (Digitaria insularis) in Brazil, ACCase inhibiting herbicides have become an excellent choice for post-emergence control of this species. Therefore, this work was developed with the objective of evaluating the efficacy and interaction of haloxyfop-clethodim tank mixtures to sourgrass control. The experiment was carried out in a greenhouse of IFSULDEMINAS, Campus Machado, in 2017, with randomized block design and six replications. Plots consisted of 1L-plastic pots filled with a mixture of sieved clay soil and commercial substrate, properly fertilized. A 4x4 factorial scheme was adopted, in which four were the doses of clethodim (0, 27, 54 and 108 g ha-1), and four were the doses of haloxyfop (0, 15.6, 31.2 and 62,4 g ha-1). At the time of application, full tillering stage was registered for the plants. Percentage control was evaluated at 21 and 28 DAA, and residual mass of dry matter at 28 DAA. Haloxyfop was more effective than clethodim to control sourgrass, reaching 96.7% of control at 28 DAA, at the dose of 62.4 g ha-1. The contribution of haloxyfop in the mixtures was more significant than clethodim for controlling sourgrass, ensuring the effectiveness of the combinations. All mixtures evaluated were considered additive, suggesting this FOP-DIM combination does not promote efficacy problems. The mixtures of clethodim and haloxyfop were effective to control sourgrass.",
