The same in vitro assay showed that PAA also reduced the growth of other oomycete fish pathogens, including Saprolegnia ferax (100% reduction at 20 mg/L), and
Aphanomyces astaci (67% reduction at 30 mg/L).
After the introduction of the American crayfish species, Pacifastacus leniusculus and Orconectes limosus, during the late 19th century and concomitant highly infectious crayfish plague (
Aphanomyces astaci) A.
In similar way, many studies revealed that soil incorporation of plant materials of members of family Brassicaceae managed many soil-borne phytopathogens including Alternaria alternata,
Aphanomyces euteiches and Verticillium dahliae (Muehlchen et al., 1990; Subbarao et al., 1994; Troncoso et al., 2005).
Is a fully established arbuscular mycorrhizal symbiosis required for bioprotection of Pisum sativum roots against
Aphanomyces eusteiches?
On the basis of screening results against the motility and viability of phytopathogenic
Aphanomyces cochlioides zoospores, not only were three flavonoid derivatives 4, 50, and 71 separated from acetone extract of medicinal Chinese plant D.
The study was conducted to evaluate the efficacy of Mikania cordata leaf powder on non-specific immune response and disease resistance of Labeo rohita fingerlings against the
Aphanomyces invadans infection.
intraradices), inducen bioproteccion contra
Aphanomyces euteiches en Medicago truncatula (Hilou et al., 2013).
But the treatment, mefenoxam, is ineffective against the pathogen causing
Aphanomyces root rot (ARR) common to Midwestern soils.
Lo anterior obliga a tomar las precauciones del caso y respetar la normativa vigente al momento de introducir especies exoticas de astacidos de agua dulce, especialmente desde Europa donde muchas de las poblaciones naturales de estos crustaceos estan contaminadas con el hongo
Aphanomyces astaci Schikora, 1903, responsable de la "plaga del hongo", de transmision muy rapida y que mata al 100% de los especimenes afectados (Ackefors, 2000).
Other North American crayfishes, e.g., Procambarus clarkii and Pacifastacus leniusculus, have been introduced into Europe and are vectors of the crayfish plague,
Aphanomyces astaci, which infects and kills nonresistant European species in most cases but can also displace resident species through ecological mechanisms (Holdich and Domaniewski, 1995; S6derback, 1995; Vorburger and Ribi, 1999).
Las evaluaciones del aporte de los HFMA a la resistencia a enfermedades y plagas se han realizado con patogenos del suelo que afectan raices como Fusarium, Rhizoctonia, Pythium, Verticillum, Phytophthora y
Aphanomyces (Whipps, 2004) o nematodos (Li et al., 2006), encontrandose que la eficiencia de los HFMA en el mejoramiento de la resistencia/tolerancia difiere entre aislamientos, no es aplicable a todos los patogenos y es modulada por las condiciones ambientales (Whipps, 2004).
