“…The cultural and morphological characteristics observed in the isolates of Neopestalotiopsis spp. were similar to those described by (Dung et al 2016;Chamorro et al 2016;Essa et al 2018;Sigillo et al 2020), who first reported Neopestalotiopsis spp. as a causal agent of strawberry crown rot in different regions around the world.…”

“…Many fungal species have been associated with the disease in recent years, however, species belonging to the genus Neopestalotiopsis have been gaining prominence as emerging pathogens in strawberries (Rebollar-Alviter et al 2020). The species Neopestalotiopsis clavispora has been considered as a causal agent of strawberry crown rot in Korea (Park et al 2019), Uruguay (Machín et al 2019), Spain (Chamorro et al 2016), Argentina (Obregón et al 2018), and Italy (Gilardi et al 2019), while the species Neopestalotiopsis rosea is considered the causative agent in Egypt (Essa et al 2018), Mexico (Rebollar-Alviter et al 2020 and Taiwan (Wu et al 2021).…”

Strawberry crown rot is one of the most important diseases in Ecuador, with an incidence of up to 70% in the field. In the world, the strawberry crown rot is caused by different etiological agents, which makes efficient control of the disease difficult. In this study, 12 samples of strawberry plants were collected, at different stages of disease development, to determine the causative agent in Ecuador. The fungal isolates, consistent with the isolation, were identified and characterized using molecular and morphological approaches, and finally, Koch's postulate was carried out. Based on the form of growth, mycelial color, conidial morphology, and molecular characteristics (sequencing of the ITS and EF-1α region), the pathogen associated with the symptoms showed 99% similarity with the species Neopestalotiopsis mesopotamica. The result of Koch's postulates showed symptoms similar to those observed in field plants, in addition, the same inoculated isolate was recovered from artificially inoculated tissues. This is the first report of this fungus causing strawberry crown rot in Ecuador and in the world.

“…Neopestalotiopsis species were known as endophytic, parasitic, and saprobic fungi [2,10]. Currently, some of them were most as parasitic [22,9,18]. As an endophytic and parasitic fungus, Neopestalotiopsis had been reported that the host was the plant, not yet was reported from the mushroom.…”

Neopestalotiopsis is one of pestalotioid fungi. Neopestalotiopsis has versicolourous in the third cell (median cell). This genus is identified as pathogenic and endophytic fungi in the plant. Neopestalotiopsis strain X1 was isolated from Xylaria stromata assumed as endophytic fungi. The surface sterilization was conducted, then isolated into PDA (1/2 receipt of potato dextrose). The morphology was observed in a fresh PDA medium. Genomic DNA was extracted and amplified for the Large Subunit region. A phylogenetic tree was built using RAxML Black Box. The morphology showed that the five cells in a conidium were an appearance with the black color of the septate in the third cell (median cell). The appendage on the basal cell was only a single tubular appendage. The appendage on the apical was two until three tubular appendages. The phylogenetic tree showed that Neopestalotiopsis strain X1 was Neopestalotiopsis zimbabwana. The sequence was deposited into GenBank as MW422813. This study was the first report for Neopestalotiopsis species isolated from micro-mushroom (Xylaria stromata).

“…The result is a limited number of approved active substances of fungicides for the protection of heathers against foliar pathogens, thus creating the risk of too frequent use of agents with the same mode of action and the development of pathogen resistance to the active substances used. The existing literature data on the effectiveness of fungicides in the protection of various plant species against fungi of the genus Pestalotiopsis indicate the possibility of using for this purpose agents such as carbendazim, chlorothalonil, mancozeb, prochloraz and iprodione in the protection of heathers [Hopkins 1996, McQuilken andHopkins 2004], chitosan in the protection of guava [El-Argawy 2015], copper oxychloride, mancozeb, methyl thiophanate in the protection of som [Ray et al 2016] and thiram in the protection of strawberry [Essa et al 2018]. The research on the protection of various species of ornamental plants against foliar pathogens, conducted for more than a dozen years, has shown the possibility of using not only fungicides but also growth stimulants, foliar fertilizers, and plant extracts that can limit the development of disease symptoms [Jeliazkova et al 2012, Salamone et al 2009, Wojdyła 2016.…”

In the protection of heathers against shoot dieback caused by Pestalotiopsis sydowiana, the highest percentage effectiveness of 92.6% to 100% was found on plants sprayed 12 times every 7 days with the active substances: iprodione, pyraclostrobin + boscalid and trifloxystrobin and with the biotechnical agents containing: microcrystalline chitosan and extract from grapefruit seed and pulp, with an efficacy of 76.9% to 100%. The active substances like chlorothalonil, fluopyram + trifloxystrobin, iprodione, pyraclostrobin + boscalid, as well as microcrystalline chitosan and extract from grapefruit seed and pulp also stimulated plant growth. Heather plants sprayed with these agents and also those sprayed with cyprodinil + fludioxonil, trifloxystrobin and potassium carbonate + monopotassium phosphate were found to produce the highest number of new shoots. An increase in the fresh weight of the aboveground parts of the heather plants of more than 55.7% compared with the control plants was found after spraying the plants with the active substances such as: fluopyram + trifloxystrobin, iprodione, pyraclostrobin + boscalid, cyprodinil + fludioxonil, trifloxystrobin and with the biotechnological agents containing microcrystalline chitosan extract from grapefruit seed and pulp, and potassium carbonate + monopotassium phosphate. Similarly, the highest average dry weight of the aboveground parts was found after the application of these agents.
