ResumoThe great growth of Salvina molesta can damage multiple uses of water.The use of herbicides may be an alternative of control and the addition of adjuvants to the spray solution can improve absorption by the plant, contributing to the effectiveness of the herbicide.The objective of this study was to evaluate the efficiency of the herbicide imazamox added adjuvants in the S. molesta control.Imazamox 900 g a.i.ha -1 was used, added to 0.5% of Dash ® , Veget'oil ® , Agral ® , Nimbus ® , Aterbane ® , and LI 700 ® and control, with 15 repetitions, totaling 7 treatments.The application was performed with a CO 2 pressurized sprayer, 206 kPa pressure, and a spray volume of 200 L ha -1 .The efficacy evaluation performs at 7, 15, 21, 30, 45, and 60 days after application (DAA) and 30, 45, and 60 DAA, destructive analysis of the plants and estimated fresh (g) and dry (g) weight were performed.Dash ® and LI 700 ® controlled 10% of the plants, Agral ® and Aterbane ® 15% and Veget'oil ® and Nimbus ® 20% at the 15 DAA until 60 DAA.All treatments caused regrowth and vegetative growth of the plants.At the 30 and 45 DAA, the more reduction in fresh
