Najafiniya  M.,  Bagheri  A., Azadvar M. & Salehi M. 2016. The situation of witches broom disease of sour lime in Iran. Plant Pathology Science 5(2):23-31.

Lime is one of the most important economic and horticultural plants in the southern part of Iran. Among the diseases of citrus in south of Iran, Witches Broom Disease of Lime (WBDL) is one of the major citrus diseases. The causal agent of WBDL is a phytoplasma with the proposed name, Candidatus Phytoplasma aurantifolia. The symptoms of disease start with appearance of witches broom at one-side of the infected tree. The disease then spread to whole parts of plant showing leaf proliferation, shortened internodes, small and pale green leaves, no formation of any spine, flower or fruit and finally death of the infected plants. To control the disease, integrated management and cultural practices has shown to be effective methods. Elimination of symptomatic trees as well of the newly emerged infected branches, chemical or mechanical weed control and a periodic spraying by systemic pesticides against the vector insect, or a combination of these methods is highly recommended. Among the control measures, chemical control of the vector has showed is very effective for reducing the disease spread and severity.

Samavat S, Salehi Vozhdehnazari M, Sayyad-Amin P (2022) Inhibitory effects of essential oils and extracts of medicinal plants on plant pathogenic fungi and bacteria. Plant Pathology Science 11(1):113-121.         Doi: 10.2982/PPS.11.1.113.
 
The use of essential oils and extracts of medicinal plants is one of the environmentally friendly methods in the management of plant diseases caused by fungi and bacteria. The antimicrobial effect of essential oils and extracts of various medicinal plants such as thyme, cloves, savory, garlic, licorice and fennel has been proven and their active ingredient has also been identified. Based on these studies, the possibility of introducing, formulating and using essential oils and extracts of medicinal plants or any of their components with antimicrobial properties, as an alternative method of using chemical toxins in the management of fungal and bacterial diseases of plants can be provided.

Alizadeh Aliabadi A, Faghihi MM, Salehi M, Ghasemi A (2022) Dynamics of emergence and spread of citrus huanglongbing disease in Iran. Plant Pathology Science 11(2):11-21.  Doi: 10.2982/PPS.11.2.11

Introduction: Huanglongbing or Fruit Greening is one of the major citrus diseases in Iran that has spread to most of the country's citrus growing provinces. In this study, the prevalence trend of the disease in seven provinces was investigated and analyzed. Materials and Methods: Citrus orchards in Sistan-Balochestan, Hormozgan, Bushehr, Khuzestan, Fars, Kerman and Mazandaran provinces were visited and samples suspected of having this disease were collected, in 2007-2009 and 2017-2019 years. After DNA extraction from the samples, the PCR test was performed using the specific primers OI1/OI2c and A2/J5. Results: It was found that the percentage of infected specimens, infected areas and number of hosts of Candidatus Liberibacter asiaticus, the causative agent of this disease, has increased over this period. At the end of this period, some samples of oranges, tangerines, grapefruits, bitter oranges, Lisbon lemons and Mexican limes were obtained from the provinces: Kerman, Hormozgan, Sistan-Baluchestan, and Fars were infected with the disease. Conclusion: The study of the disease during these years showed that: the infected areas and the host range of the disease have expanded a lot during this period, and the spread of the disease in citrus cultivation areas in the south of the country has been with a gentle slope. The reduction of the disease-carrying psyllium population during these years seems to have been effective in slowing down the spread of the disease.
