ABSTRACT
The consistent introduction of a wide variety of diseases to plant life, such as fungal species, microbes, nematodes and viruses, necessitates the development of an advanced immune response for its survival. The hormone levels of salicylic acid, Jasmonic acid and ethylene play a major role in controlling how defense responses and associated indicators are activated in plants. Numerous biotic and abiotic agents could indeed make plants resistant to pathogen attack. In programs for incorporated disease management, the use of abiotic plant defense enhancers has long been taken into consideration. Natural activator substances, like alginates, has also been emphasized because of their ecologically responsible genetic makeup, capacity to activate plant defense systems and ability to promote growth. Ecofriendly substances that can stimulate plant growth even while causing pathogen tolerance and influencing the exclamation of the salicylic acid-dependent defense pathway include polysaccharides and the oligosaccharides derived from them.
