Resumo: | ABSTRACT: Persistence of an herbicide is defined as the ability to maintain the integrity of its molecule and chemical, physical, and phytotoxic properties in the environment where it was applied. Knowledge of persistence has implications both for the toxicity generated on species grown in succession and for the period in which the herbicide controls weeds. This study aimed to assess the persistence of the herbicide saflufenacil in an Oxisol by means of bioassays. Two experiments with the application of 29.4 g ha-1 of saflufenacil were carried out under field conditions: the first in the 2011/2012 season and the second in the 2012/2013 season. Soil samples were collected at depths of up to 10 cm at different times after application. Subsequently, two bioassays were carried out in a greenhouse by using beet (Beta vulgaris L.) and cucumber (Cucumis sativus L.) as bioindicators. The studies were carried out in a completely randomized design with four replications. Treatments consisted of periods after saflufenacil application (0, 5, 10, 15, 25, 35, 50, and 100 days). The crop was also considered as a factor. Stand, height, and phytotoxicity of plants were assessed in both agricultural seasons at 14, 21, and 28 days after sowing (DAS), as well as shoot fresh (SFM) and dry matter (SDM) at 28 DAS. In general, saflufenacil persistence was between 25 and 35 days. Beet was more sensitive to the presence of saflufenacil in the soil when compared to cucumber. Herbicide effects were higher in the 2012/2013 season when compared to the 2011/2012 season. |
