Golmohammadi, M. & Banihashemian S. N. 2017. Management  method of citrus  blast disease. Plant Pathology Science 6(2):1-13.

Citrus bacterial blast is reported from many parts of citrus growing areas of world. It is one of the most important diseases of citrus in north of Iran, but its damage is different because of year-to-year climate variability. The disease is caused by two species of Pseudomonas. In those years that air humidity and temperature are suitable, these bacterial species can cause serious damage to citrus trees. The main symptom of citrus blast disease is wilting and dieback of branches. Some practices for management of this disease are illustrated in this article.

Rafiei V and Banihashemi Z (2019) Fungi in desert areas of Yazd province. Plant Pathology Science 8(2):110-121. DOI:10.2982/PPS.8.2.110.
Introduction: The Fungi which are able to grow at the temperatures above 40 degrees Celsius are known as thermophilic fungi. So far, no study has been carried out on fungi in desert areas of Iran so the present study was aimed to isolate and identify the fungi in desert areas of Yazd province. Materials and Methods: Four desert regions of Yazd province were visited and samples were taken from soil and plant roots. The fungi were isolated by soil dilution method and were cultured on potato-agar extract medium. Genus and species of fungi were identified by valid identification keys. Results: Eighteen fungi from eight genera vs. Aspergillus, Penicillium, Alternaria, Ulocladium, Stemphylium, Paecilomyces, Rhizopus and Fusarium were identified in this study. Conclusion: The species of Penicillium and Aspergillus were the most abundant species in desert soils of this province. All fungi identified in this study are reported for the first time from Iranian desert soils.

Habibi A, Ghaderi F,  Banihashemi Z (2023) Coevolution of Polystigma amygdalinum through a process of host tracking. Plant Pathology Science 12(1):36-45.
     Doi: 10.2982/PPS.12.1.36
Introduction: The almond tree (Prunus dulcis) and its wild relative, the mountain almond tree (Amygdalus scoparia), grew up together in the province of Fars in Iran over decades. Red leaf blotch disease caused by Polystigma amygdalinum is one of the most important almond diseases in the world. This research was conducted with the aim of investigating the evolution of this pathogen on its wild and domestic hosts. Materials and Methods: Ascospores suspension of P. amygdalinum isolates obtained from almond in Fars province was inoculated to almond and mountain almond seedlings in a greenhouse. The progress of the disease in the diseased leaves of mountain almond compared to almond was investigated by sectioning with a freezing microtome from the spots created on the leaves. Results: Red leaf blotch spots appeared on the leaves of both types of almonds. Statistical analysis of test data showed that P. amygdalinum isolates from almond are able to cause disease in mountain almond with significantly lower severity, and longer incubation period. Conclusion: The results of this research show that P. amygdalinum, the cause of red leaf blotch disease, have coevolved on cultivated almond through a process of host tracking.
