“…PCR identification (Kokaeva et al, 2018a) was found that 40% of leaf samples contain A. solani DNA in Temryuk (location 4, Figure1), 35% -in Kislovodsk (7), 7% in Rostov (6), 0% in Armavir (6). Our research with PCR identification of C. coccodes (Belov et al, 2018) revealed 54% of leaf samples with DNA of this fungus in Rostov (3), 28% in Slavyansk-na-Kubani (5), 4% in Armavir (6), 0% in Temryuk (4). In present research it was analyzed only one leaf sample per field; possibly, it was too small to find C. coccodes or A. solani.…”

“…However, it is a less aggressive pathogen than A. solani or A. arborescens because it is less capable of colonizing host tissue (Tymon, Cummings, et al, 2016). A. infectoria (also section Infectoriae) was found on potato crops in Russia and was proven to cause infection on potato (Belosokhov et al, 2017;Orina et al, 2010).…”

“…Even though small‐spored Alternaria have been reported as causal agents of brown spot disease on potato since 1984 (Droby et al., 1984), some authors still consider it controversial whether A. alternata is just an opportunistic secondary invader (e.g., Adolf et al., 2020). Many studies proved that A. alternata alone can infect tomato and potato leaves (e.g., Belosokhov et al., 2017) and Schmey et al. (2023) showed that small‐spored Alternaria are true pathogens on wild tomato species (Schmey et al., 2023).…”

Alternaria spp. cause different diseases in potato and tomato crops. Early blight caused by Alternaria solani and brown spot caused by Alternaria alternata are most common, but the disease complex is far more diverse. We first provide an overview of the Alternaria species infecting the two host plants to alleviate some of the confusion that arises from the taxonomic rearrangements in this fungal genus. Highlighting the diversity of Alternaria fungi on both solanaceous hosts, we review studies investigating the genetic diversity and genomes, before we present recent advances from studies elucidating host–pathogen interactions and fungicide resistances.TaxonomyKingdom Fungi, Phylum Ascomycota, Class Dothideomycetes, Order Pleosporales, Family Pleosporaceae, Genus Alternaria.Biology and host rangeAlternaria spp. adopt diverse lifestyles. We specifically review Alternaria spp. that cause disease in the two solanaceous crops potato (Solanum tuberosum) and tomato (Solanum lycopersicum). They are necrotrophic pathogens with no known sexual stage, despite some signatures of recombination.Disease symptomsSymptoms of the early blight/brown spot disease complex include foliar lesions that first present as brown spots, depending on the species with characteristic concentric rings, which eventually lead to severe defoliation and considerable yield loss.ControlGood field hygiene can keep the disease pressure low. Some potato and tomato cultivars show differences in susceptibility, but there are no fully resistant varieties known. Therefore, the main control mechanism is treatment with fungicides.

“…The most numerous and widespread potato diseases are infections caused by microorganisms. Various common fungal, bacterial pathogens of potato diseases include representatives of the genus Phytophthora, Alternaria, Fusarium, Rhizoctonia , and others, causing yield losses from 10 to 60% 3–6 . Thus, there is a need for developing effective means and techniques for protecting potato crops and increasing yields.…”

BACKGROUND: For the first time, the biological activity of slow-release fungicide formulations for suppressing potato pathogens deposited in a degradable poly-3-hydroxybutyrate/sawdust base has been obtained and investigated. RESULTS:The slow-release fungicide formulations (azoxystrobin, azoxystrobin + mefenoxam, and difenoconazole) were studied in vitro and in vivo in comparison with commercial analogues. In in vitro cultures of phytopathogens, the deposited fungicides showed an inhibitory effect comparable to commercial analogues, limiting the growth of colonies of Phytophthora infestans, Alternaria longipes, Rhizoctonia solani and Fusarium solan (2.0-2.3 times relative to the negative control). In laboratory experiments, the use of deposited fungicides was accompanied by earlier germination and more active growth of potatoes against the background of a decrease in the area of plant damage and an increase in yield. In the field experiment, the deposited fungicides suppressed the development of Phytophthora and Alternariosis in the rhizosphere during the entire growing season and reduced the area of plant damage by pathogens by 10-15%, which is two times less than in the groups of plants treated with commercial preparations. The higher biological activity of the embedded fungicides ensured the maximum number of tubers undamaged by pathogens and the total yield of 22-23 t ha −1 , which exceeded the yields in the groups with commercial fungicides (18.4-20.8 t ha −1 ). CONCLUSION: The slow-release fungicide formulations deposited in a degradable P(3HB)/sawdust base are effective in protecting potatoes from pathogens and increasing yields and have an advantage over commercial counterparts.
