“…Iturritxa et al, 2013). De igual manera existen evidencias que P. radiata es las más susceptible a la infección (Correll et al, 1991;Wingfield et al, 2008), lo que toma mayor relevancia al ser la especie de conífera más con mayor extensión de siembra del mundo (Critchfield andLittle, 1966, Pérez et al, 2004), siendo Chile el país con la mayor superficie plantada de P. radiata con más de 1.5 millones de hectáreas establecidas y viveros con plántulas para doblar esta cantidad (Carrasco et al, 2016). Este riesgo no es exclusivo de este país Sudamericano, también lo comparte países como Argentina, Uruguay, Sudáfrica, Australia y Nueva Zelanda que poseen importantes cantidades de plantaciones de esta conífera (Fernández & Sarmiento, 2004).…”

“…Sin embargo, estudios más recientes demuestran susceptibilidad en otras coníferas y de Pseudotsuga menziesii (T. R. Gordon, Kirkpatrick, Aegerter, Wood, & Storer, 2006). Pese a que los potenciales hospedantes de Fusarium circinatum son la mayoría de las especies del género Pinus, se han descrito algunas aparentes resistencias y diferencias cuantitativas en susceptibilidad (Carrasco, Sanfuentes, Durán, & Valenzuela, 2016). En otras especies, como, por ejemplo, Pinus lambertiana Douglas y Pinus jeffreyi Balf., se ha comprobado la susceptibilidad al patógeno mediante experimentos en invernadero, pero no en campo (A. J. J.…”

RESUMENLa enfermedad denominada con el nombre de Chancro Resinoso del Pino es causada por el hongo ascomicete Fusarium circinatum Nirenberg et O'Donnell (teleomorfo= Gibberella circinata). Afecta numerosas especies de coníferas y a la fecha tiene presencia en todos los continentes del mundo, a excepción de la Antártida. Debido a las variaciones climatológicas y ambientales a nivel global que han favorecido el rango biológico de dispersión de la enfermedad, sumado al comercio internacional de madera y sus derivados con medidas cuarentenarias insuficientes, actualmente el hongo amenaza con expandirse a zonas libres de la infección. En las zonas donde ya se ha confirmado la presencia de la enfermedad se reportan importantes pérdidas económicas en viveros, semilleros forestales, plantaciones silvestres y comerciales de distintas especies de coníferas. No menos importante pérdida ecosistémica causada por la inestabilidad de los bosques y nichos ecológicos altamente sensibles a las variaciones florísticas. Actualmente es considerada la patología más importante a nivel mundial de las coníferas, tanto silvestres como comerciales, y no posee tratamiento curativo por lo que los esfuerzos están centrados en el tratamiento preventivo. Dentro del ámbito científico destacan las investigaciones en resistencia genética del hospedante y el uso de controladores biológicos que prometan resultados significativos.Palabras claves: Sanidad forestal; Biocontrol; Selección y Mejora genética; Epidemiología; Fisiología del estrés en plantas.

“…Pitch canker disease of pine trees and Douglas fir, caused by the fungus Fusarium circinatum Nirenberg & O'Donnell (formerly known as Gibberella circinata ), is one of the most important pathogens of Pinus species and is listed as a quarantine or regulated pest in Europe and other regions of the world (Carrasco, Sanfuentes, Durán, & Valenzuela, ; Ganley, Watt, Kriticos, Hopkins, & Manning, ; Pfenning et al, ; Vettraino, Potting, & Raposo, ). The pathogen has been reported in most of the world's pine production zones, especially in those where Pinus radiata is intensively planted, either on adult forests or nurseries (EPPO, ; Wingfield et al, ).…”

Fusarium circinatum is the causal agent of pitch canker, a destructive disease that threatens natural and planted pine forests around the world. Although pitch canker has caused problems in Spain and Portugal, concerning Europe as a whole, the fungus is not established across the pine distribution area. Its dispersion by wind and/or insect vectors could nevertheless play a role in the colonization of currently uninfected stands. It is therefore crucial to develop monitoring tools for its detection. To this end, we assessed the molecular detection of the pathogen in environmental samples of bark beetles and passive spore traps, collected in two infected Pinus radiata plantations in Basque country, Spain. The spread pattern of F. circinatum was assessed by an experimental design that included insect and spore traps installed at the centre, at the edge and outside the plots. Our results showed that F. circinatum was detected in both types of samples, at almost all collection dates. In both type of samples, positive detections were mainly found at the centre of the plots, a lower proportion at the edge, and very few outside. This suggests that long‐distance dispersion of Fusarium circinatum does not rely on wind spore dispersal neither on insect flight. Our study also shows that molecular methods are a powerful tool to monitor the pathogen in environmental samples.

“…are cosmopolitan fungi that have pathogenic forms and are capable of parasitizing different gymnosperm and angiosperm species (Bosland, 1988). It has been identified as a causal agent of rot and wilt symptoms (Dean et al, 2012;Zuo et al, 2015;Carrasco et al, 2016), causing important economic losses in more than 200 crops around the world (Pérez et al, 2017). Fusarium species are frequently the causal agents responsible for damping-off in forest nurseries, and sometimes they cause important damage in very young plantations in the field (Vivas et al, 2012;Martín-Rodrigues et al, 2015;Fajardo-Mejía et al, 2016).…”

The Causal Agent of Damping-off in Pinus patula (Schiede) and Pinus tecunumanii (Schwerdtf.)

et al. 2019

Damping-off is considered one of the most serious risks for production of Pinus seedlings due to the significant losses it can cause in forest nurseries. In Colombia there is little information about the etiology of this limiting disease. Different species of the genus Fusarium have been reported as causal agents, which makes the study of the pathogenicity of this genus relevant. In this study, strain 001F of Fusarium oxysporum was obtained from the diseased tissues of P. patula seedlings. The identity of the species was determined by sequencing the internal transcribed spacer (ITS) regions. Pathogenicity tests confirmed the ability of strain 001F to cause damping-off symptoms in P. patula and P. tecunumanii. Thus, F. oxysporum strain 001F represents a significant risk to produce tree species in Colombia and in other parts of the world.
