| Nota de conteúdo | ABSTRACT<br/>Background: Weed management is a challenge in paddy rice production,<br/>mainly due to the dispersal of a population resistant to herbicides.<br/>Objective: To assess the efficacy of chemical weed control in the offseason to <br/>reduce weedy rice and other species in water-seeded or drilled<br/>rice.<br/>Methods: Two experiments were carried out in a flat field to water-seeded<br/>or drilled rice, in randomized block design. The water-seeded system<br/>treatments were organized in a split-plot design. In the plot were evaluated<br/>two water management in the off-season (with or without continuous<br/>flooding), and in the subplot nine herbicides-treatments were evaluated<br/>(Check, clomazone at 0.72 and 1.08 kg a.i. ha-1, oxadiazon at 1.00 and<br/>1.50 kg a.i. ha-1, oxyfluorfen at 0.312 and 0.48 kg a.i. ha-1, S-metolachlor at<br/>1.44 kg a.i. ha-1, and flumioxazin a 0.075 kg a.i. ha-1). In the drilled rice<br/>experiment, the treatments were organized in a two-factor factorial. The<br/>factor A was nine herbicides treatments (the same herbicide and rates<br/>applied in water-seeded experiment) and the factor B was two application<br/>time (73 and 43 days before of rice-sowing).<br/>Results: Off-season management was efficient to reduce weedy rice<br/>infestation only on the paddy rice system using the pre-germinated seeds.<br/>In this assay, flumioxazin was an efficient alternative to giant arrowhead<br/>control, however the selectivity of this herbicide treatment needs to be<br/>studied. In dry-seeded system, herbicide sprayed in off-season reduced<br/>barnyardgrass infestation until the paddy rice sowing.<br/>Conclusions: The off-season management was efficient to reduce weedy<br/>rice and giant arrowhead infestation in water-seeded system, and<br/>barnyardgrass infestation in drill-seeded system.<br/><br/>Keywords:<br/>drill-seeded<br/>water-seeded<br/>residual herbicides<br/>pre-germinated<br/>Oryza sativa |
