Gray mold caused by Botrytis cinerea, is one of the most important postharvest diseases on fresh fruits and vegetables worldwide. The disease may start in the field and remain as a latent infection and then develop after harvest, during transportation, packaging, storage and marketing. Nowadays, application of fungicides is the main strategy to control the gray mold disease in conventional agriculture. The presence of fungicide residues in edible fruits and vegetables is a concern for consumers because pesticides are known to have potential harmful effects. Therefore, the search on finding the safe and effective disease control strategies has been accelerated. Integrated management of the disease by using some methods like optimal method of irrigation and fertilization, biological control, use of bioagents, disinfection of fresh fruits and vegetables after harvesting, storing and shipping in a cool and dry condition with low humidity and suitable ventilation are suggested.

Today the ecological, ecological and sociological problems of conventional agriculture are of great concern. Accordingly, organic farming should be viewed as an alternative approach that provides safe and healthy nutrition by eliminating synthetic pesticides and fertilizers with the least loss of nutrients and energy and the least negative impact on the environment. Organic farming is guided by the idea that all processes within an agro-ecosystem are interdependent and it aims to achieve efficiency, diversity, self-sufficiency, self-regulation and resilience through natural processes using the ecological possibilities of the agricultural system. Disease management in organic farming is based on maintaining biodiversity and soil health. In this review, a brief description of organic farming is given first. The next other practices used in organic farming to control disease include sanitation, organic soil improvement, long-term crop rotations, reduced tillage, the right harvesting time, the selection of crops and varieties, and the use of catch crops and also, catch crop cultivation. In conclusion, organic farming has the potential to improve the recycling of biomass and optimize the availability of nutrients and ensure favorable soil conditions for plant growth.

The world's population is growing rapidly. To feed this large population, more crops must be produced. The broad use of fertilizers, pesticides and other inputs increases the productivity of existing agricultural lands and the amount of food production, but this increase in yield causes damage to the environment, soil degradation and the destruction of its natural microbial population. To prevent these harmful effects of the chemicals, an eco-friendly approach is needed to ensure human health and the environment. In the innovative view of agricultural production, there is a growing demand for the use of biofertilizers instead of agrochemicals. The use of beneficial microorganisms can be a new strategy to improve plant health and productivity. Natural microbial populations play an important role in the solubilizing and mineralizing of soil nutrients, which is very important for plant growth and development. Among the various microbial populations, fungi known as plants growth promoting fungi (PGPF) have recently received increasing attention. For decades, plant growth promoting fungi such as Trichoderma, Penicillium, Phoma, Aspergillus and Fusarium have been studied. Studies have shown that these fungi, regulate plant growth without environmental pollution and increase plant tolerance to plant pathogens. In this review a brief description of plant growth promoting fungi is given first. In the following, the nature and composition of these fungi as well as the mode of actions, formulation and related challenges will be concidered.

Abshang, A., & Mirtalebi, M. (2024). The role of fungal volatile organic compounds in plant disease management. Plant Pathology Science, 13(1), 65-74.
Volatile organic compounds (VOCs) are carbon-based organic chemicals derived from primary or secondary metabolism which are released as gases from different solids and liquids. Many intra- and inter-kingdom ecological interactions between living organisms take place through VOCs. The volatile organic compounds released by pathogenic fungi have a negative effect on the growth of plants. The release of volatiles by these fungi in the soil inhibits growth and results in a decrease in shoot length, root surface area, and plant biomass. In addition to negatively impacting plant development, these compounds generated by pathogenic fungi can also serve as growth regulators, modifying plant architecture and stimulating growth. The promotion of plant growth can, consequently, be beneficial for pathogens by offering a larger habitat for surface colonization and increasing their survival.
These compounds also increase the biosynthesis of strigolactones and root growth in interaction with fungi, facilitating the identification of mycorrhizal fungi for the roots, increasing the colonization of fungi on the roots. The antibiotic effects of VOCs are involved in the inhibition of many plant pathogens. Some of these fungal compounds have inhibitory activity in the soil and some have insect repellent and nematicidal properties.
