“…Srivastava et al, (2010), Nath et al, (2015) also obtained significant reduction in bacterial wilt incidence in solanaceous crop by application of P. fluorescens alone or in consortia. For the effective management of any soil borne disease, the introduced antagonist should colonize root (Weller, 1984).…”

“…lycopersici (FOL), causante de la disminución de 60% del rendimiento y afectando la calidad del producto (Cai et al, 2003;Srivastava et al, 2010). Para esta enfermedad se reconocen tres razas del patógeno, que se distinguen por su virulencia en materiales diferenciales de tomate y que contienen diferentes genes de resistencia (Masato et al, 2005).…”

ResumenEl objetivo de este estudio fue conocer los efectos histológicos y los relacionados a vigor con la aplicación del extracto de Heliopsis longipes sobre plántulas de tomate inoculadas con Fusarium oxysporum f. sp. lycopersici (FOL). El extracto de H. longipes se asperjó a una concentración de 300 mgL -1 en plántulas de tomate, posteriormente se realizó la inoculación con FOL por inmersión de raíces. Veinte días después se tomaron los datos de incidencia y severidad, encontrándose que la aplicación del extracto provocó una disminución de 15% y 80% respectivamente para estas variables mientras que para altura de la planta se presentó un incremento de 14.3%. En longitud de raíz y peso seco de hojas y tallo se observó un decremento en los resultados; sin embargo, estos valores estuvieron por encima de los obtenidos para plantas inoculadas con FOL. Se encontraron cambios histológicos ocurridos por la infección de FOL así como por la aplicación del extracto, que consistieron en la modificación de la distribución de los haces vasculares en la raíz, así como en el incremento del área relativa del córtex de raíz y tallo y la disminución del número de vasos del xilema de la raíz. Estos resultados indican que la aplicación del extracto tiene un efecto sobre los síntomas de marchitamiento causados por FOL. AbstractThe aim of this study was to determine the histological effects and those related to vigor with the application of an extract of Heliopsis longipes on tomato seedlings inoculated with Fusarium oxysporum f. sp. lycopersici (FOL). H. longipes extract was sprayed at a concentration of 300 mgL -1 in tomato seedlings subsequently inoculated with FOL by root immersion. Twenty days later incidence and severity data were taken, finding that the application of the extract caused a decrease of 15% and 80% respectively for these variables whereas for plant height there was an increase of 14.3%. In root length and dry weight of leaves and stem there was a decrease in the results; however, these values were higher than those obtained for plants inoculated with FOL. Histological changes were found by effect of FOL infection as well as for extract application, which consisted in modifying the distribution of vascular bundles in root, as well as increasing the relative area of root and stem cortex and reducing the number of xylem vessels in root. These results indicate that the application of the extract has an effect on wilting symptoms caused by FOL.

“…Several practices such as use of the resistant or tolerant cultivars, crop rotation, and fumigation to decrease the damage of FW have been suggested before (Yu, 2001). Also, fungicide application is common, but may not be effective especially when the wilt appears late in the season (Srivastava et al, 2010).…”

Improvement of Soil Properties, Growth of Cucumber and Protection against Fusarium Wilt by Piriformospora indica and Two Industrial Organic Wastes

The current work was focused on characterizing bagasse ash (BA) and press mud (PM) as soil amendments and to study their effect in combination with the endophytic fungus Piriformospora indica on Fusarium wilt (FW) of cucumber caused by Fusarium oxysporum f. sp. cucumerinum (Fo). Whereas BA and PM improved almost all physico-chemical properties of the soil evaluated, seed treatment with P. indica had no such effect. In shake culture in potato dextrose broth (PDB) medium amended with aqueous extracts of BA and PM, alone or in combination, production mycelial mass of Fo was significantly decreased by PM extract, while production mycelial mass of P. indica was highly improved. The colonization rate of cucumber roots by P. indica as determined by microscopy was highly increased by increasing amounts of BA, PM and BA+PM added to the soil. Seed treatment of cucumber with P. indica before plant cultivation in non-amended soil significantly decreased the disease severity of FW and improved plant growth. When seed treated with P. indica was sown into soil amended with BA, PM or the combination of both, the disease severity was even more reduced than after seed treatment with P. indica alone. In this respect, amendment with PM was more effective than with BA, and the combinations were more effective than the single treatments. Hence, there is a scope to integrate PM and BA as soil amendments in combination with P. indica for eco-friendly FW management, improving soil properties and growth of cucumber plants.
