Abstract

Considering the effectiveness of glufosinate in the pre-harvest desiccation of soybeans, but with little comparative information between the formulations of this herbicide, the objective of this study was to evaluate commercial products based on glufosinate in the pre-harvest desiccation of soybeans. The experiment was carried out in Palotina, Paraná state (PR), Brazil, 2020-2021 crop season. A randomized block design with four replications was used. The treatments were composed by the application, in the pre-harvest soybean desiccation, of the glufosinate formulations (400 g ai ha-1): Finale®, Gamonium®, Off Road®, Patrol® SL, Fascinate® BR, Trunfo®, in addition to of the control without application. The percentage of defoliation and maturation (focused on the evaluation of pods), grain moisture and yield were evaluated. No differences were observed between the glufosinate formulations in the defoliation and maturation of the pods of soybean plants, in the application in pre-harvest desiccation. However, further studies are needed so that any differences in performance between glufosinate formulations can be better characterized. None of the glufosinate formulations differed from the control without application in yield, and all reduced grain moisture without differences between them. This indicates the feasibility of applying glufosinate in R7.2, as a pre-harvest desiccation management of soybeans.
