“…It is known that the nature and extent of the manifestation of external signs of the disease, especially with complex pathogen damage, are determined by examining the distribution of species composition in the pathocomplex, location of infection, degree of aggressiveness and features of the relationship of pathogens in a particular mycosociety, level of plant resistance, and influence of external environmental factors [ 35 , 47 ]. In this study, it was shown that all identified species can contribute to the pathogenesis of tracheomycosis wilting of pepper plants in the Republic of Crimea.…”

“…The ability of F. oxysporum (FOSC) and F. solani (FSSC), as the main pathogens, to cause symptoms of vascular wilt in plants of the Solonaceae family has also been noted by other scientists in their studies. Recent studies conducted in North Carolina [ 47 ], Mexico [ 48 ], Poland [ 49 ], South Korea [ 50 ], Pakistan [ 29 ], and India [ 15 ] have shown that these two dominant pathogens have remained a serious threat to pepper, tomato, physalis, eggplant, and potato production in these regions.…”

Fusarium wilt pathogens represent an ongoing threat to pepper production worldwide. This is the first report providing data on the molecular identification of Fusarium fungi that cause wilt in pepper in the southern regions of Russia. Monitoring of the Fusarium infection on pepper was carried out in 2019–2022 in two economically important regions of this culture production: the Krasnodar Krai and Crimea. Based on a phylogenetic analysis of the translation elongation factor (EF1a) and the internal transcribed spacer (ITS), as well as the macro- and micromorphological characteristics of the fungi, the causative agents of Fusarium wilt have been identified. The causative agents identified as representatives of the Fusarium species composition included: F. clavus, F. solani, F. oxysporum, F. verticillioides, F. commune, F. torulosum, and F. sporotrichioides. Depending on the region, the specifics of biodiversity and the ratio of these species in pathocomplexes were noted. In Crimea, wilting could be attributed to all of the identified species; in the Krasnodar Krai, F. verticillioides and F. clavus were found to contribute to wilting. The pathogenicity test showed that the pathogens of pepper wilting in Russia, in addition to the already known F. oxysporum and F. solani, are the species F. clavus and F. verticillioides. This is the first report on the ability of these species to cause Fusarium wilt in pepper cultures. The obtained data will be of practical value for the development of biological control measures for fungi of the genus Fusarium, which cause pepper wilt in areas of industrial production and seed production. In addition, data on species composition and aggressive isolates will be used in a pepper breeding program for resistance to Fusarium wilt.

“…'Fortamino' (Enza Zaden Salinas, CA) was added in 2018 to gain information on a vigorous and Fusarium oxysporum f. sp. lycopersici race 3 resistant rootstock because of the emergence of race 3 in North Carolina at the time of this study (Adhikari et al, 2020). Non-grafted plants of both scion cultivars were used as controls.…”

Grafting high yielding tomato cultivars (Solanum lycopersicum L.) onto vigorous rootstocks can increase marketable yields, but questions remain regarding optimal cultural and growing conditions such as pinching and plant spacing. This study addressed some of the dynamics between grafted plants and cultural practices. Two scions, ‘Tasti-Lee’ (TL) and ‘Mountain Fresh Plus’ (MFP) were grafted onto each of three rootstocks, ‘Beaufort’, ‘Arnold’, and ‘Shield’. Plants were pinched (removal of main shoot to induce both axillary shoots to grow) or non-pinched, and spaced at 56 or 61 cm. All 32 grafted treatments were compared to the grower standard: non-grafted TL and MFP spaced at 46 cm, which were non-pinched. Fruit quality traits including soluble solids content, pH, lycopene concentration, and titratable acidity were recorded for fruit harvested from tomatoes grafted onto ‘Arnold’, ‘Beaufort’, ‘Shield’ and non-grafted TL. The overall effect of grafting TL and MFP onto vigorous rootstocks ‘Arnold’, ‘Beaufort’, and ‘Fortamino’ increased marketable yields per hectare by 24-35% compared to non-grafted grower standards. The rootstock ‘Shield’ did not significantly increase yields with either scion. TL had a more positive response to grafting than MFP. ‘Arnold’, ‘Beaufort’, and ‘Fortamino’ significantly increased TL fruit size, but the fruit size results were not as significantly impacted by graft treatments for MFP. Plants spaced at 56 compared to 61 cm generated similar yields. Pinched plants significantly increased yields over non-pinched plants by 15% in 2018 but did not impact yield in 2017. No consistent difference was observed between pinched and non-pinched plants with regard to fruit size, only plants grafted with ‘Shield’ benefited significantly from being pinched. Soluble solids content, pH, total lycopene concentration, and titratable acidity differed slightly between grafted and non-grafted plants but was unlikely to positively or negatively affect overall perception of fruit quality in tomatoes. A partial budget analysis revealed that grafting with ‘Arnold’ or ‘Beaufort’ consistently increased profits in this low-disease field.

“…tomada de: [13] Por otro lado, Fusarium oxysporum (figura 2) es un hongo ampliamente distribuido en suelo y abarca un complejo variable de cepas con características morfológicas y patológicas diferentes, algunas de estas cepas son saprótrofos y endófitos comensales que colonizan la raíces, pero no representan una amenaza para la planta, es más, cepas específicas pueden generar un beneficio para el huésped ocasionando protección ante diferentes patógenos que la pueden afectar, sin embargo, Fusarium oxysporum también presenta un complejo de cepas que permiten categorizarlo como hongo emergente, ya que invaden diferentes tipos de plantas distribuidas en el mundo ocasionando síntomas característicos como clorosis en las hojas, necrosis de los sistemas vasculares o muerte del huésped ya que este coloniza el xilema.

La propagación de plagas afecta diferentes especies de plantas generando un desafío para el mantenimiento del control de la inocuidad alimentaria, diferentes investigaciones concuerdan con que el uso permanente de plaguicidas químicos genera a largo plazo afecciones de salud en las diferentes comunidades bióticas y abióticas, además ocasiona resistencia en los diferentes fitopatógenos a los componentes químicos que contienen los plaguicidas, lo cual promueve la proliferación de dichos microorganismos. En la búsqueda de soluciones a esta problemática, se han desarrollado varias investigaciones, de las cuales un amplio y prometedor campo es el uso de aceites esenciales (AE) de diferentes plantas, dichas investigaciones han mostrado resultados positivos en la inhibición de la actividad antifúngica. El presente artículo de revisión se realiza con el fin de comparar el efecto inhibitorio que presentan tres aceites del género Cinnamomum spp., Cinnamomum zeylanicum, Cinnamomum cassia y Cinnamomum camphora frente a tres hongos fitopatógenos, Alternaria solani, Fusarium oxysporum y Rhizoctonia solani distribuidos en el suelo a nivel mundial, analizando cual es el método de extracción y el método de caracterización química usado más frecuente, adicionalmente se comparan los resultados obtenidos por distintos autores en cuanto la actividad inhibitoria que estos AE tienen en los fitopatógenos mencionados a diferentes CMI obteniendo conclusiones variables. Cinnamomum zeylanicum, parece ser hasta ahora el aceite esencial más estudiado frente a tres especies de hongos mencionadas y presenta un prometedor antifúngico para las nuevas tecnologías de control de plagas, se propone continuar investigando en el comportamiento inhibitorio del aceite de canela.
