“…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.

“…Among the main problems that restrict this cropʼs field productivity increase is the lack of improved varieties (Peña-Lomelí et al, 2020), phytosanitary problems (Ayala-Armenta et al, 2020), and inadequate agronomic management (López-Ramos et al, 2020). Under protected agriculture conditions, there is greater control of environmental variables compared to open field agriculture conditions (Machorro, 2020).…”

Objective: To evaluate the effect of different doses of foliar and soil silicon dioxide fertilization on the economic profitability of husk tomato (Physalis ixocarpa Brot. ex Hornem.) cv. 'Querétaro' cultivation under plastic paddings and macro-tunnel conditions. Design/methodology/approach: Ten treatments were evaluated at different concentrations of silicon dioxide fertilization on soil and foliar application: T1: Control treatment (T), T2: Fertilization with silicon dioxide 20, 40, 60 g on soil and 100, 150, and 200 ppm foliar (S20/100F), T3: S20/150F, T4: S20/200F, T5: S40/100F, T6: S40/150F, T7: S40/200F, T8: S60/100F, T9: S60/150F and T10: S60/200, distributed in random blocks. Economic profitability indicators such as Benefit/Cost ratio (B/C), Net Present Value (NPV), and Internal Rate of Return (IRR) were determined. Results: The research established that the S60/150F treatment was the one with the highest economic profitability because it promoted the highest production per hectare, which was reflected in the NPV (MX$ 336,932.97 pesos), the IRR (77.3 %), and a B/C of MX$ 1.16 pesos. Also, treatments S40/200F and S60/100F (where SiO2 was applied) reported positive cash flow, unlike the T. Limitations of the study/implications: With all research facilities closed due to the COVID-19 pandemic, no evidence related to the contribution of foliar and soil silicon bioassay has been verified. Findings/conclusions: Using SiO2 leads to a financial appreciable rebound of vital importance to be included in economic studies to facilitate the efficient management of the available capital to establish a crop whose field productivity is profitable for the producers.

“…El cultivo de tomate de cáscara tiene gran importancia económica en nuestro país; sin embargo, es seriamente afectado por diversos patógenos (Ayala-Armenta et al, 2020). Por tales motivos, es importante explorar otras opciones ecológicas que no involucren el uso y aplicación de fertilizantes minerales o pesticidas sintéticos.…”

Una de las estrategias agroecológicas que aumenta la producción agrícola es el uso de inoculantes bacterianos, los cuales carecen de los efectos tóxicos que tienen los agroquímicos. En este trabajo se evaluó el efecto de la inoculación de la rizobacteria promotora del crecimiento vegetal Pseudomonas fluorescens UM270 sobre el ciclo de cultivo de plantas de tomate de cáscara (Physalis ixocarpa) en condiciones de campo (riego) en el año 2019. Los resultados mostraron que las plantas inoculadas con la rizobacteria UM270 exhibieron efectos significativos en la altura de las plantas (14.64%), el diámetro de tallo (17.74%), el índice de biovolúmen (35.14%) y la producción de frutos cuajados en 65.54%. Esto sugiere que la cepa P. fluorescens UM270 es un excelente bioinoculante que mejora la producción del cultivo de tomate de cáscara bajo condiciones de campo.
