Severity Of The Disease

Correlations between two ecophysiological traits of 13 Fusarium strains (viz., ability to develop saprophytically in a disinfected soil and respiratory activity) and their capacity to protect a flax crop from vascular fusariosis were established for one soil type. The ability of Fusarium strains to reduce the severity of the disease (efficiency) differed greatly. The most competent ones lowered the death rate by 80%, while the least competent had virtually no effect. Classification based on strain efficiency differed depending on whether it was performed on disinfected soil or on soil not heat treated. When the abilities of strains to colonize disinfected soil were estimated by enumeration on agar plates, Fusarium oxysporum strains proved superior to Fusarium solani due to their production of more numerous conidia, and therefore greater numbers of colonies, without significantly increasing biomass. Respiratory activity ranged from moderate to low. A clear, positive correlation was found between the respiratory activity and the efficiency of the strains grown in untreated soil, while the correlation was not significant in the disinfected soil. In the latter case, however, efficiency was correlated with the saprophytic development of the strains. [Journal translation]

Different Tissues

The purple passionfruit plant, Passifloraedulis Sims, ranks second in fruit exportation in Colombia, and its main destination is the European market. However, its production is affected by several diseases, including fusariosis. This paper presents the histopathological features of different tissues affected by the pathogens Fusarium oxysporum and Fusarium solani. Both microorganisms produce similar responses on the plant: colonization of xylem vessels by hyphae and microconidia, hypertrophy and hyperplasia of the cambium, xylem and phloem; destruction of xylem fibers and amyloplasts in parenchymatous cells; and production of gels by the plant. However, there are differences in the colonization mechanism, F. solani penetrates and is concentrated especially at the collar zone, while F. oxysporum penetrates the roots and moves through the vascular system to colonize the plant.

A bean (Phaseolus vulgaris) line, A - 300, resistant to Rhizoctonia solani and Fusarium oxysporum was introduced into Ontario from Colombia. The results of tests conducted in a root-rot nursery, in a greenhouse and in a growth room showed that this bean line is resistant to Fusarium solani f. sp. phaseoli and Pythium ultimum.

Cultivated Soils

In soils of the Salinas watershed Fusarium solani and Fusarium tricinctum were found only in the cultivated soils. Propagules of Fusarium oxysporum were numerous and varied in the cultivated fields but were relatively scarce and existed essentially as a single clone in the noncultivated soils. In the Castroville watershed both F. solani and F. oxysporum were recovered from noncultivated soils fairly frequently.The 'Gibbosum' cultivar of Fusarhim roseum, the most frequently isolated fusarium from field soils, was less common in the noncultivated soils.Other fusaria, such as Fusarium episphaeria and some cultivars of F. roseum, were about as numerous in the noncultivated as in the cultivated soils. The cultivation of these soils markedly affected the makeup of the fusarium populations in them.

<p>La marchitez y pudrición seca del cogollo del agave (<em>Agave tequilana</em> var. azul) son enfermedades de alto impacto económico para este cultivo. En este trabajo se planteó determinar la implicación de <em>Fusarium</em> spp. en ambas enfermedades bajo un enfoque regional. Se colectaron muestras de raíz y suelo en 40 plantaciones comerciales ubicadas en 13 municipios de Los Altos Jalisco, importante región de cultivo de agave azul en México. De cada plantación de colecta se estimó carga de inóculo mediante un índice de <em>Fusarium</em> obtenido de unidades formadoras de colonias (<em>Fusarium</em> vs hongos totales) y se analizó su relación con pH y materia orgánica. Se obtuvieron 109 aislados caracterizados morfológicamente como <em>Fusarium</em> spp. de los cuales se seleccionaron 25 para identificación molecular con ITS y EF-1a. La selección consideró sintomatología, caracteres macro y microscópicos y prevalencia de tipologías de colonia observadas <em>in vitro</em> en medios Komada, Sabouraud, SNA y CLA. Los caracteres culturales y morfológicos evaluados fueron: coloración micelial, tamaño, forma y septación de macro y microconidios, y longitud y número de fiálides. Se asociaron cinco especies con marchitez y/o pudrición seca ubicadas en tres complejos filogenéticos: <em>F. oxysporum</em> del complejo de especies <em>Fusarium oxysporum</em> (FOSC) con 56% (46.2% suelo y 66.7% raíz) de representatividad regional; <em>F. solani, F. falciforme</em> y <em>Fusarium</em> sp. del complejo <em>Fusarium solani</em> (FSSC) (40%); y <em>Fusarium</em> sp. del complejo <em>Fusarium fujikuroi</em> (FFSC) (4%). MO y pH tuvieron correlación inversamente proporcional con Índice de <em>Fusarium</em> (<em>r2</em> = 0.68-0.70). Se postula que la marchitez y pudrición seca del cogollo de agave azul constituyen un síndrome en el cual se asocian y especializan parasíticamente diversas especies de <em>Fusarium</em>. Se encontró un aislado de los tres complejos de <em>Fusarium</em> asociados específicamente a cada tipo de síntoma y la combinación de ellos. La mayoría se asociaron a marchitez con predominancia de<em> F. oxysporum. </em>  </p><p> </p>
