The relatively short shelf life caused by pathogen attacks is one of the limiting factors that affect the fruits economic value. The estimated degradation by pathogenic agents in post-harvest care is between 20-25 percent of fruits. Management technique for the control of pathogenic fungi has been used for various purposes, including cultural, physical, chemical, biological and regulatory approaches. In terms of environmental and economic concerns, organic and traditional fruit processing systems, biological regulation would seem to have a major potential. The purpose of this research is biocontrol agents (Trichoderma sps) for the control of Apricot fruit postharvest diseases caused by various fungi known worldwide, e.g. Alternaria alternate, Aspergillus flavus, and Penicillium expansum. Biological control has been proposed as an effective, safe strategy for monitoring major fruit declines post harvests and improving crop production. Several plants and plant products have been used for plant disease control and have been found to be harmless and non-toxic. The methodology used in this research is Dual culture technique that analysed the efficacy of the biochemical agent against phytopathogens under laboratory conditions and measured the results of percentage inhibition of the pathogen by the bioagent. The conclusion of this study revealed that the Trichoderma sp caused significant inhibition of the colony diameter of fungal pathogens.
