The goal of sustainable and organic agriculture is to optimize the health and productivity of interdependent communities of soil life, plants, animals, and people. Organic plant production uses natural products and natural self-regulation processes occurring in the ecosystem. The availability of innovative applications and molecular techniques opens up new possibilities in the approach to plant protection for sustainable and organic agriculture. New strategies not only directly protect plants against pathogens but can also induce enhanced immunity that permanently protects against pathogenic strains. This review focuses on the bioactive properties of selected natural compounds (of plant and animal origin), their action on pathogens, and their roles in the mechanism of inducing plant resistance. The author presents selected activities of organic bioactive compounds, such as allicin, naringin, terpenes, laminarin, carrageenans, chitin and chitosan, and outlines the possibilities for their application in protecting crop plants against diseases. In addition, this mini review describes the mechanism of action of the above compounds as elicitors of defense reactions in the plant and the possibility of their utilization in the production of biological preparations as elements of a new plant protection strategy.

“…The antiviral activity of chitosan in animals, microorganisms, and plants has been reviewed (Chirkov 2002;Wang et al 2012). Chitosan inhibited viral infections in animal cells and prevented the multiplication of bacteriophages in infected cultures of microorganisms (Chirkov et al 2001;Chirkov 2002). In plants, chitosan induced resistance toward viral diseases and inhibited the systemic spreading of viruses and viroids so that most or all plants treated with chitosan did not develop systemic viral infection (Chirkov 2002;Rabea et al 2003).…”

In agriculture, current control of pathogens relies mainly on chemical fertilizers and pesticides. However, alternative solutions are needed due to concerns for public health, environmental protection, and development of resistant pests. Chitosan is a nontoxic, biodegradable biopolymer showing antimicrobial and plant-immunity eliciting properties. Here, we review chitosan antimicrobial activities, modes of action, and the elicitation of plant defense responses. The major points are the following: (1) Chitosan exhibits various inhibitory efficiency against bacteria, fungi, and viruses;(2) the five main modes of action of chitosan are electrostatic interactions, plasma membrane damage mechanism, chitosan-DNA/RNA interactions, metal chelation capacity of chitosan, and deposition onto the microbial surface; (3) the elicitation of plant defense responses by chitosan may be related to various pathogenesis-related proteins, defense-related enzymes, and secondary metabolites accumulation, as well as the complex signal transduction network. The facing problems and strategies for antimicrobial mechanism research and agricultural application of chitosan are also discussed.

“…Chitosan affects the plant itself inducing resistance to the plant with a phytopathogen and chitosan induces a wide spectrum of defensive reactions in the plant,1–3 which limit a systemic spread of the viruses and viroids over the plant and lead to the development of the systemic acquired resistance 4. Chitosan applied by spraying or inoculating leaves protected various plant species against local and systemic infection caused by alfalfa mosaic virus (ALMV), tobacco necrosis virus (TNV), tobacco mosaic virus (TMV), peanut stunt virus (PSV), cucumber mosaic virus (CMC), and potato virus X (PVX) 3, 6. Chitosan possesses an antiviral activity by its ability to induce resistance toward viral diseases in plants, to inhibit viral infections in animal cells, and to prevent the multiplication of bacteriophages in infected cultures of microorganisms 6, 7.…”

In this study, guanidinylated chitosan hydrochloride (GCH) was synthesized and its structure was characterized by UV-vis and FTIR. The degree of substitution of guanidinylated chitosan was confirmed by elemental analysis. In vitro antiviral activity of guanidinium derivative on local infection and systemic infection of tobacco mosaic virus (TMV) inoculated were evaluated by semileaf method using different modes of GCH application and antiserum assay. Meanwhile, the morphological characteristic of virus treated by GCH was performed by transmission electron microscope. The results showed that GCH had better antiviral activity than chitosan. The average inhibitory rate of GCH on local infection was 84%, which was much higher than that of chitosan hydrochloride. It was shown that the guanidinylated chitosan was an efficient passivator, and its antiviral effect decreased after mechanical inoculation. The guanidinylated chitosan increased the resistance of plant against TMV and decreased the infection of the virus. The electron microscope photograph exhibited that GCH not only directly altered the configuration of TMV but also congregated and reduced the virus.
