ABSTRACT The research work was carried out in the province of Otuzco, La Libertad region in the month of June with the objective of evaluating the effect of the adjuvant polyether- polymethylsiloxane on the efficacy of systemic herbicides in the control of the weed Rumex acetosella. The experiment used a randomized complete block design, with 3 blocks; 6 treatments which were glyphosate, metribuzin, atrazine, glyphosate + adjuvant, metribuzin + adjuvant, atrazine + adjuvant and an absolute control without applying. Treatments T5 (glyphosate + adjuvant) and T2 (glyphosate) stood out in phytotoxicity index with an average of 9 and 8 respectively 30 days after application, which indicates "permanent damage". In terms of plant mortality for Rumex acetosella, the most efficient treatment was T5 (glyphosate + adjuvant), where total plant death occurred 22 days after application. In percentage of regrowth, T2 (glyphosate); T5 (glyphosate + adjuvant) and T7 (atrazine + adjuvant) maintained efficient control by not having regrowth until the end of the trial; and the least efficient was T3 (metribuzin) that reached an average of 3.7% regrowth since it lost its residual effect 15 days after application. There is an improvement in the efficiency of atrazine and metribuzin when using adjuvant but they did not stand out in the trial. The adjuvant did not improve the action of glyphosate, being toxic it had similar results when applied alone.
