Induced Systemic Resistance by Microbial Stimulants against Plant Diseases
Plants are exposed to different environmental stresses in their habitats (biotic or abiotic) which often resulted in several diseases and declined in crop production. These are major concerns to crop producers and scientists. Habitat-imposed biotic stress is one of the most common problems of crop p...

| Sumario: | Plants are exposed to different environmental stresses in their habitats (biotic or abiotic) which often resulted in several diseases and declined in crop production. These are major concerns to crop producers and scientists. Habitat-imposed biotic stress is one of the most common problems of crop production. The use of chemical-based pesticides had been earlier reported to control plant diseases, but the residual effects of excessive usage of synthetic inorganic pesticides necessitate the use of biological control agents which play important safety roles against causal agents of plant diseases. Symbiotic associations between diverse microorganisms and plant roots had been proven to have enormous impacts on their growths and survival; induced systemic resistance (ISR) is part of the mechanisms through which plant growth-promoting bacteria and fungi stimulate the plant growth and resistance to pathogens. Many of these microbes act as stimulants which can be exploited for boosting nutrient uptake and pest control and protect crops from environmental stresses for better growth. This chapter focuses on the plant diseases, the mechanism of infection of causal agents, and the microbial stimulants as nutrient enhancers in crop production as well as their potentials in biological control of plant diseases through ISR. |
