In vivo Antiphytoviral Activity of Essential Oils and Hydrosols From Origanum vulgare, Thymus vulgaris, and Rosmarinus officinalis to Control Zucchini Yellow Mosaic Virus and Tomato Leaf Curl New Delhi Virus in Cucurbita pepo L.

Abstract: In the last decades, the interest in biological activity of natural compounds has been growing. In plant protection, essential oils have been reported to exhibit antiviral, antimycotic, and antiparasitic activities, and are regarded as promising for the formulation of safe antimicrobial agents. Attention has also been focused on hydrosols, the by-products of hydro-distillation of essential oils. Their production is easy, fast, and cheap, and they seem to arise less concern for human health than essential oils.… Show more

“…Essential oils (EOs) are complex mixtures of volatile, lipophilic and aromatic low-molecular-mass secondary plant metabolites, usually obtained through steam distillation, that are usually associated with an important role in plant protection [ 14 , 15 ]. The bulk of EOs are composed of terpenes, but they also include non-terpene components such as phenols and alcohols.…”

“…However, effective crop protection with this method is possible only for a limited number of viruses. Additionally, it is possible to eliminate viruses in vitro, which is accomplished with different techniques (e.g., thermotherapy or meristem culture) which are all expensive, time-consuming, and are not suitable for all plant/virus pathosystems [ 1 , 2 ]. Thus, the search for alternative methods of crop protection against plant viruses is of great significance.…”

“…The detailed mechanism of such activity is yet to be fully explored. It has been hypothesized that EO components could either directly inactivate viral particles or induce resistance/tolerance response in the host [ 2 ]. The mechanisms of action of EOs are versatile due to the complexity of composition and synergism of bioactive compounds compared with synthetic antiviral substances (e.g., acyclovir) that act in a manner specific to a particular type of virus.…”
