Aleahmad P, Ebrahimi L (2020) Biological control method of postharvest fungal diseases of apple. Plant Pathology Science 9(2):95-107.     DOI: 10.2982/PPS.9.2.95.
Apple postharvest diseases are usually caused by a wide range of pathogenic fungi. Postharvest rot of this crop is one of the most important economic diseases and also one of the main factors in reducing the lifespan of this crop. In contrast, our current knowledge of the occurrence and latent contamination during storage and its epidemiology is limited. The pathogenic fungi Botrytis cinerea and Penicillium expansum causing gray mold and blue mold, respectively, are the most common pathogens in the cultivation areas, which are usually inhibited by the use of synthetic fungicides. However, due to the growing concern over the use of synthetic fungicides, alternative control measures such as using physical treatments, natural compounds, and biocontrol agents are highly desired. Although no method has been approved as a definitive method of postharvest diseases management, the effectiveness of yeasts such as Candida saitoana, bacteria such as Rahnella aquatilis, and fungal species such as Trichoderma harzianum has been suggested.

Aleahmad P.  Ebrahimi L (2022) The role of endophyte fungi in plant disease management. Plant Pathology Science 11(1):100-112.        
  Doi: 10.2982/PPS.11.1.100.
Plant diseases usually cause economic damage and reduce growth and crop yield.  Treatment of plant diseases with chemical toxins can result in environmental side effects, the emergence of resistance in pathogens, and loss of beneficial soil microorganisms, so the search for alternative methods such as identification and use of antagonistic microorganisms for disease treatment has been considered by researchers. A set of endophyte fungi that grow without damage or symptoms in host plant tissues and are known to be biological control agents of some plant diseases. Endophyte fungi with different mechanisms such as the production of antibiotic metabolites, competition, induction of resistance, and hyperparasitism of the pathogen weaken or eliminate the pathogens. These fungi can also help increase the growth and resistance of host plants to various stresses by producing antioxidant and antitumor compounds, as well as various growth hormones.
