Plant-Derived Essential Oils and Aqueous Extract as Potential Ingredients for a Biopesticide: Phytotoxicity in Soybean and Activity against Soybean Mosaic Virus
Resumen
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

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.

Relative incidence of cucurbit viruses and relationship with bio-meteorological variables
Pozzi, Elizabeth Alicia; Bruno, Cecilia Inés; Luciani, Cecilia; Celli, Marcos Giovani; Conci, Vilma Cecilia; Perotto, Maria Cecilia (Springer, 2020-02)Environmental heterogeneity can shape the plant-virus relationship, furthering the appearance of new diseases in crops, or altering disease incidence and severity. In this work, we studied the virus association with ... -

Striking differences in the biological and molecular properties of onion and garlic isolates of onion yellow dwarf virus
Celli, Marcos Giovani; Torrico Ramallo, Ada Karina; Kiehr, Mirta; Conci, Vilma Cecilia (Springer, 2013-06)Complete nucleotide (nt) and deduced amino acid sequences of two onion yellow dwarf virus (OYDV) isolates showing mild and severe symptoms in onion but being unable to infect garlic were determined. The genomes consisted ...
