Dr. Abbas Nasehi is presently working as Post-Doc fellow at University of Tehran, Karaj, Iran. During his study and three Post-Doc fellowships, he has conducted researches on biological and cultural control of disease, seed pathology, evolution of pathogenicity and virulence, phylogenetic analysis and species concepts, genetic diversity, as well as gene expression. Dr. Nasehi has been the author of more than 40 papers in peer-reviewed ISI-indexed journals, national and international conferences. Also, he has been the reviewer of several ISI and non-ISI journals.


Downy mildew is considered as a common fungal-like disease in agricultural crops worldwide; hence, this disease induces major food losses and damages valuable natural ecosystems. However, chemicals have been widely employed for management of the disease, but they are very harmful to consumers, growers, and the environment, as well as costly. Therefore, biological control such as the use of biologically antagonistic organisms has recently been considered as an alternative and an ecofriendly method to deal with plant diseases. Among such organisms, several endophytic fungi have been successfully used to control plant pathogens. Endophytes produce special substances, such as metabolites, which prevent the host from being attacked successfully by fungi and pests. Moreover, indirect effects are related to the induction of disease resistance such as lignification of cell walls and production of antifungal compounds, or promotion of plant growth. Studying endophytic fungi and their mechanisms of effects in the leaves of the host plants is crucial in the management of downy mildews by biofungicide. This presentation summarizes the previous studies that have used fungal endophytes as biological agents to control downy mildews with a particular emphasis on their identification, modes of action and biocontrol efficacy.
