| Sumario: | Soybean mosaic disease, caused by the soybean mosaic virus (SMV), is responsible for major
losses in yield and seed quality worldwide. Although resistant cultivars are used for its prevention
and control, an alternative strategy could consist of applying environmentally friendly antimicrobial
agents, such as extracts and essential oils (EOs) of aromatic plants. This study assessed an extract of
Achyrocline satureioides and EOs of Minthostachys verticillata, Origanum vulgare, and Thymus vulgaris
in terms of their phytotoxicity in soybean. Since all the concentrations tested were found to be safe,
the activity of each product against SMV was then assayed in vivo, i.e., in experimentally infected
soybean plants. The parameters measured were plant height, wet weight, and virus titer. All the
treated plants had a greater height and weight than those in the viral control group. The EOs of M.
verticillata (0.80 mg/mL) and T. vulgaris (0.71 mg/mL) inhibited the production of viral antigens, as
determined by an ELISA test. These findings could encourage further studies aimed at developing
an effective biopesticide against SMV. |
