<br/><br/> <br/><br/>Abstract<br/><br/>This study aimed to assess the effectiveness of four weed control strategies in forest setting stands linked by a set of Atlantic<br/>Forest tree species. Four treatments were employed: mechanical – manual hoeing and mowing; chemical – glyphosate<br/>herbicide application in the total area; chemical – cultural – herbicide spraying and herbaceous legume intercropping;<br/>chemical-mechanical – herbicide planting in rows and mowing in the interrows. Diameter, crown area and soil cover<br/>percentage of the eight tree species were assessed at 18 months. Herbicide spraying in total area promoted the greatest<br/>reduction in weed populations, as well as superior growth in height, diameter, crown area and soil cover of the tree<br/>species. More interventions were necessary in the treatment of mechanical weed control that has also shown the least<br/>growth of the tree species. The chemical method was the most effective in weed control and promoted the greatest<br/>growth of the tree species.<br/><br/>Keywords: weed control, competition, mechanical control, chemical control and glyphosate.
