Última Effect water activity on in vitro mycelial growth of Neofusicoccum spp. infecting blueberry Ciencia e Investigación Agraria Latorre,Bernardo A; Díaz,Gonzalo A; Reed,María P. Stem canker in blueberries (Vaccinium corymbosum L.) is a disease which is widely distributed around the world and of growing importance in Chile, associated with Neofusicoccum species. The purpose of the present work was to study the effects of water activity (a w) and temperature on mycelial growth in vitro of N. arbuti, N. australe and N. parvum, obtained from blueberries with symptoms of stem canker. According to the results obtained, 25 °C was the optimum temperature for mycelial growth of N. arbuti, N. australe and N. parvum. These species presented minimal growth at 35 °C and none at 0 and 5 °C. The effect of a w on mycelial growth was significant (P≤0.001) and varied with the species of Neofusicoccum and the temperature. At 25 °C, the...

Cuttings of five grapevine (Vitis vinifera) rootstocks were wounded and immediately inoculated with suspensions (approximately 5x10³ conidia- mL-1) of either Phaeomoniella chlamydospora, Phaeoacremonium aleophilum or a mixture of both species. The presence of these endophyte fungi affected the quality of each of the five rootstocks. Among the roostocks investigated in this study, 1103P and 101-14 MG were less susceptible to the infection caused by Pa. chlamydospora wd Pm. aleophillum.

Ano: 2009 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-16202009000300005 Germicidal effect of UV light on epiphytic fungi isolated fromblueberry Ciencia e Investigación Agraria Latorre,Bernardo A; Rojas,Susana; Díaz,Gonzalo A; Chuaqui,Hernán. The present study examined the inactivation effect of ultraviolet (UV) light on the conidia of Botrytis cinerea Cladosporium cladosporioides, C. herbarum and Pestalotiopsis clavispora, common pathogens of blueberry (Vaccinium corymbosum), often found as epiphytes. The fungi were grown at 20°C in acidified potato dextrose agar (APDA) in the dark; conidial suspensions (10(6) conidia mL-1) were placed the bottom of 5 cm glass Petri plates with a maximum height of 0.5 mm. Uncovered plates were immediately exposed to either UVA (λ = 361 nm), UVB (λ = 302 nm) or UVC (λ = 254 nm) at doses between 40 and 110 mJcm². The results were expressed as survival ratios Nt/N0 (the number of colonies obtained after conidia were exposed to UV...

G. A., Diaz, J., Auger, X., Besoain, E., Bordeu, and B. A. Latorre, 2013. Prevalence and pathogenicity of fungi associated with grapevine trunk diseases in Chilean vineyards. Cien. Inv. Agr. 40(2): 327-339. Trunk diseases in grapevine (Vitis vinifera) have been identified as a major problem in the wine and table grape industries around the world, reducing the productivity, quality and longevity of vineyards. The present study examined 694 wood samples from the cordons and trunks of vines with trunk disease symptoms in 67 Chilean vineyards located between Copiapó (27°18' S) and Los Angeles (37°42' S). A total of 1,363 fungal isolates were obtained from diseased cordons and trunks with dark brown streaking, yellowish soft-spongy cankers and brown hard...
