“…Also, it was observed that, when a high dose of nitrogen fertilizers were used, suppression of virus disease symptoms occurred but without an effect on the virus concentration [19]. Significant efforts have been made to find components that can be used as inhibitors of virus infection and replication that works as fungicides and give direct protection to the crops against fungi, but such substances are not available yet [20].…”

“…For field application, using the antiviral chemical substances as a spray on the foliar parts is the most common way in application, because this method is easy, simple and inexpensive equipments are not needed [20,44]. Granular method is convenient, promising, and most importantly it is safe on the environment, because the substance kept at the same spot of application [20]. Seed treatment is ignored and is not being used anymore as one of the application methods [45].…”

“…Many antiviral natural substances have been obtained during the previous fifty years. Some have been used as a crude extract that may contain a number of non-active substances, while others have been used as purified or partially purified, thus the chemicals included are not identified, nor the mechanism of these compounds [20]. The kind of solvent that is used in plant extraction depends on the kind of the chemicals needed to be obtained, the purpose of use, the conditions of extraction and the storage medium [21].…”

Viruses are microorganisms that infect all kinds of living organisms including plants, and cause remarkable lose in crop production. Although pesticides showed that they can protect plants from pest infections, there are no effective substances that can be used as potent virucides. Therefore, there is a continuous demand to produce chemicals in order to stop and cure viral infections in plants. However, toxicity and carcinogenicity issues were always attributed to chemical pesticides. Screening of natural products shined in the dark to find new safe virucides. The philosophy of selecting those plants is oriented towards plants that can protect themselves from viral infections. Plants have been reported as virus inhibitors and are able to prevent infection of viruses by inducing systemic resistance in noninfested parts of the plants, such as Boerhaavia diffusa, Clerodendrum aculeatum. Other plants defend themselves against virus infections; these plants contain ribosome inactivating proteins [RIPs], such as Phytolacca Americana, Mirabilis jalapa, Dianthus caryophullus. The methods used for extraction, separation, identification of those antiviral compounds are documented and discussed in this review.

“…A large number of wild and cultivated plants are known to contain endogenous proteins that act as virus inhibitors [1][2][3][4][5][6][7][8][9]. These antiviral substances ,mostly of protein nature, are referred as ribosome-inactivating proteins [6,10].…”

Antiviral proteins were isolated, from host plants, following treatment with an antiviral glycoprotein, extracted from the roots of Boerhaavia diffusa plants. It was found to be active against isometric as well as an isometric viruses in their respective hypersensitive and systemic hosts. The biologically active principal was isolated and purified. Estimation of proteins, from the leaf samples of N.glutinosa plants, indicated higher concentration of new proteins in plants whose two basal leaves were treated 24 hours earlier with an aqueous solution of the glycoprotein. SDS-PAGE analysis studies on partially purified antiviral principal of protein nature revealed that the size of band in L 3 (after 24 hours) was 30 Kda along with very dark and prominent bands. The size of band recorded in rest treatments was of 36 Kda and 50 Kda.

Parštein F., Sedlák J., Svobodová L., Polák J., Gadiou S., 2013. Results of in vitro chemotherapy of apple cultivar Fragrance -Short communication. Hort. Sci. (Prague),.Th e eff ect of the chemotherapy with ribavirin on the elimination of the pome fruit viruses from in vitro grown plants of infected apple cv. Fragnance has been investigated. Th e results of ELISA and RT-PCR testing proved the presence of mixed infection of Apple stem pitting virus (ASPV), Apple chlorotic leaf spot virus (ACLSV) and Apple stem grooving virus (ASGV) in the initial fi eld-grown tree of this apple cultivar. Obtained actively growing in vitro shoots with welldeveloped leaves and shoot tips were subsequently used for chemotherapy with ribavirin. Attempts to fully eliminate viruses by ribavirin in lower concentration 20 mg/l were not successful. However in vitro plants of one mericlone (FR1R20) sanitated from ASPV and ASGV, which were infected with ACLSV only after the fi rst chemotherapy cycle, were subjected to repeated treatment on medium with higher ribavirin concentration 100 mg/l. Th e success of chemotherapy with ribavirin at 100 mg/l was 76% for ACLSV elimination after the second round. In the course of both chemotherapy cycles (20 mg/l and 100 mg/l), in vitro plants did not display symptoms of phytotoxicity.
