The article provides information on the distribution of the area of pistachio forests by altitude, slope exposures, age classes is given. Growing on slopes of different exposures, pistachio and sparse forests fulfill soil-protective, waterprotective and water-regulating role. The diversity of pistachio forms allows selecting the best forms for introduction into culture. Pistachio forests serve as a source of valuable nuts for the local population. In harvest years, the collection of pistachio fruits brings good income to the local population. However, it is necessary to work together with the local population on sustainable use of pistachio plantations and preservation of their biodiversity, as there is a negative impact of anthropogenic factors. The data on the impact of major pests and diseases of pistachio plantations are presented. Due to the influence of pests and forest diseases, the yields are reduced and the condition of pistachio forests deteriorates. Timely and effective control measures against forest pests and diseases are necessary. Analysis of the current state and solution of the issues of biodiversity conservation of pistachio plantations is of great scientific and practical importance.

“…The global economic value of pistachios is estimated to be over $1 billion annually, with the top five producers being the United States, Iran, Turkey, Syria and Greece ( Mateos et al, 2022 ). Septoria pistaciarum —the causal agent of Septoria blight of pistachios, is an important pathogen reported across all pistachio-growing regions, including: the United States ( Young and Michailides, 1989 ), Middle-East ( Akgul et al, 2011 ), Central Asia ( Ahmad et al, 2011 ) and the Mediterranean ( Eskalen et al, 2001 ; Gusella et al, 2021 ; Lopez-Moral et al, 2022 ; Drais et al, 2023 ).…”

Septoria pistaciarum, a causal agent of Septoria leaf spot disease of pistachio, is a fungal pathogen that causes substantial losses in the cultivation, worldwide. This study describes the first pan-genome-based survey of this phytopathogen—comprising a total of 27 isolates, with 9 isolates each from 3 regional units of Greece (Pieria, Larissa and Fthiotida). The reference isolate (SPF8) assembled into a total of 43.1 Mb, with 38.6% contained within AT-rich regions of approximately 37.5% G:C. The genomes of the 27 isolates exhibited on average 42% gene-coding and 20% repetitive regions. The genomes of isolates from the southern Fthiotida region appeared to more diverged from each other than the other regions based on SNP-derived trees, and also contained isolates similar to both the Pieria and Larissa regions. In contrast, isolates of the Pieria and Larissa were less diverse and distinct from one another. Asexual reproduction appeared to be typical, with no MAT1-2 locus detected in any isolate. Genome-based prediction of infection mode indicated hemibiotrophic and saprotrophic adaptations, consistent with its long latent phase. Gene prediction and orthology clustering generated a pan-genome-wide gene set of 21,174 loci. A total of 59 ortholog groups were predicted to contain candidate effector proteins, with 36 (61%) of these either having homologs to known effectors from other species or could be assigned predicted functions from matches to conserved domains. Overall, effector prediction suggests that S. pistaciarum employs a combination of defensive effectors with roles in suppression of host defenses, and offensive effectors with a range of cytotoxic activities. Some effector-like ortholog groups presented as divergent versions of the same protein, suggesting region-specific adaptations may have occurred. These findings provide insights and future research directions in uncovering the pathogenesis and population dynamics of S. pistaciarum toward the efficient management of Septoria leaf spot of pistachio.

“…During the research, S. pistaciarum and S. pistachina species belonging to the Septoria family were isolated from the genes of fungal isolates that cause leaf spot disease in different areas where the pistachio plant grows. In Italy, as well as in other regions, septoriosis is one of the most common diseases among pistachio orchards [9]. Septoria histaciae, S. histaciarum and S. histacina are the causative agents of this disease in the Mediterranean region.…”

This article introduces the results of research on the harmful effects of septoria, a fungal plant pathogen infecting pistachio, on pistachio fruit weight and yield. In recent years, there has been an increase in the negative effects of various diseases on the pistachio crop. Therefore, maintaining their yield and developing modern disease control measures remains one of our main goals. The measures to combat this disease and the effectiveness of the most suitable chemical preparations are presented below.
