Plants frequently experience unfavourable changes in the environment. Crop yield is significantly reduced by abiotic stresses around the world. Salt found in both irrigated and non-irrigated soils, is one of the most important abiotic stresses. Soil salinity stress is accountable for loss of plant growth, crop yield, and productivity. In addition, the infections caused by phytopathogens also cause biotic stress, which could further reduce produce yield and quality. Most fungal phytopathogens in saline soils are salt-tolerant and are difficult to control using traditional approaches.

In recent years, the significance of plant growth promoting microbes (PGPM) in the regulation of abiotic stresses has increased. Some PGPMs have been shown to be able to withstand salt stress, offering the possibility of using these PGPRs as a promising option to reduce salinity stress in plants.

Trichoderma is regarded as the most advantageous and versatile fungal genus, providing food security for a population that is exponentially expanding and also resolving agricultural issues with relatively few negative impacts. Trichoderma species are widely used as biocontrol agents in management of fungal diseases of crop plants demonstrating mycoparasitism against a wide range of phytopathogens. The agronomical importance of Trichoderma also lies in its potential of producinga range of enzymes, bioremediation etc.
