The objective of this study was to evaluate the tolerance of sunflower (Helianthus annuus) to acetyl-coenzyme A carboxylase (ACCase)-inhibiting herbicides and to temporarily delay the growth of the forage grass (Brachiaria ruziziensis), avoiding competition and allowing the reestablishment of pasture. A randomized block design with four replicates was used in both experiments. The following treatments were applied in Experiment 1: I) 10 g ai ha-1 tepraloxydim; II) 20 g ai ha-1 tepraloxydim; III) 12.5 g ai ha-1 fluazifop-p-butyl; IV) 25 g ai ha-1 fluazifop-p-butyl; V) 12 g ai ha-1 clethodim; VI) 24 g ai ha-1 clethodim; VII) 6 g ai ha-1 haloxyfop-methyl; VIII) 12 g ai ha-1 haloxyfop-methyl; IX) unhoed check, and X) hoed check. The treatments applied in Experiment 2 were: I) hoed check; II) unhoed check; III) 10 g ai ha-1 tepraloxydim; IV) 20 g ai ha-1 tepraloxydim; V) 12.5 g ai ha-1 fluazifop-p-butyl, and VI) 25 g ai ha-1 fluazifop-p-butyl. All herbicide treatments were selective for the sunflower crop. The use of reduced rates of graminicides is a feasible option to delay the growth of B. ruziziensis, reducing its ability to compete the sunflower. All herbicide rates applied suppressed the growth of B. ruziziensis, permitting subsequent pasture reestablishment. However, tepraloxydim (20 g ai ha-1), clethodim (24 g ai ha-1), and haloxyfop-methyl (12 g ai ha-1) promoted poorer recovery of the forage grass. |
