Cultivar Effects on the Interaction between Free-Living Plant-Parasitic Nematodes and the Fungal Pathogen Rhizoctonia solani in Potato

2017

Crop damage is associated with infection by plant pathogens but can also arise through abiotic factors. However, the plant pathogens are involved in biotic interactions with other plant pathogens, and these interactions may differ depending of the cultivar of the crop. Here, the interaction between the fungus Rhizoctonia solani (AG3) and free-living plant-parasitic nematodes was investigated in a pot experiment with different potato cultivars. No synergistic interaction between R. solani and plant-parasitic nematodes was found, instead there was an effect of treatment with lower tuber yield when nematodes occurred alone. There were differences among the cultivars regarding incidence of black scurf, dry weight of stems and tubers, and there was interactive effects between treatment and cultivar regarding dry weight of stolons and roots. Therefore, results concerning incidence and damage of R. solani and/or plant-parasitic nematodes found for one cultivar may not be applicable to other cultivars.Resumen El daño en el cultivo se asocia con infección por fitopatógenos, pero también puede surgir a través de factores abióticos. No obstante, los patógenos de plantas están involucrados en interacciones bióticas con otros patógenos, y estas interacciones pudieran diferir dependiendo de la variedad del cultivo. Aquí, se investigó la interacción entre el hongo Rhizoctonia solani (AG3) y nematodos fitoparásitos de vida libre en un experimento en macetas con diferentes variedades de papa. No se encontró una interacción sinergística entre R. solani y los nematodos fitoparásitos, en cambio, hubo un efecto de tratamiento con rendimiento más bajo de tubérculo cuando los nematodos estaban solos. Hubo diferencias entre variedades en relación a la incidencia de costra negra, peso seco de los tallos y los tubérculos, y hubo efectos interactivos entre tratamiento y variedad en relación al peso seco de los estolones y las raíces. De aquí que los resultados concernientes a la incidencia y daño de R. solani y/o nematodos fitoparásitos que se encontraron para una variedad pudieran no ser aplicables a otras.

“…The hymenia do not cause damage to the plant but basidiospores enclosed in them may serve as source of subsequent infections (Banville et al, 1996). Other manifestations of infection include poor and uneven stands; premature dying; pruned stolons and sprouts; lesions on roots, stems and stolons; rosette appearance; girdled stems; necrosis in the stem-end of tubers; russeting of skin; and cracked and malformed tubers (Carling et al, 1989;Hide et al, 1992).…”

“…Another, Verticilium dahliae is a soilborne pathogen that causes Verticillium wilt disease, which affects over 200 plant species, including the tomato (Fradin and Thomma, 2006). R. solani is a pathogen that causes various diseases, affecting the roots and tubers of different plant species (Carling et al, 1989), and induces to a significant loss of potato crops (Yanar et al, 2005).

The purpose of this study was to assess the effectiveness of essential plant oils from Vitex agnus-castus L. ), and plant essential oils were applied at concentrations of 0.5, 1, 1.5, 2, 5 and 10 (μL/Petri -1 ) into the 5 mm diameter wells opened on the Petri dish surface. After that, the Petri dishes incubated at 22±2 °C. The results of this study, the essential oil of M. communis, at a dose of 10 μL/ Petri, inhibited the 100% mycelium growth of V. dahliae, S. sclerotiorum and R. solani. The highest dose of VAC essential oil was also 100% inhibited V. dahliae and S. sclerotiorum. The LC 50 and LC 90 values of M. communis and VAC essential oil calculated for V. dahliae, FORL, S. sclerotiorum and R. solani. This plant extracts were shown by in vitro conditions to be potential antifungal agents.
