B.A. Latorre, R. Torres, T. Silva, and K. Elfar. 2013. Evaluation of the use of wound-protectant fungicides and biological control agents against stem canker (Neofusicoccum parvum) of blueberry. Cien. Inv. Agr. 40(3): 537-545. Economically, blueberry (Vaccinium corymbosum) has become a very important fruit crop in Chile, and stem canker (Neofusicoccum parvum) has frequently been observed as a major disease. The symptoms are characterized by partial or total death of the foliage associated with extensive reddish-brown canker lesions at the base of the stems. Pruning wounds appear to be the main infection route. In this study, fungicide pastes and biological control agents were evaluated for their effectiveness as pruning wound-protectants against N. parvum.... |

Gray mold (GM) caused by Botrytis cinerea is a major disease of grapes (Vitis vinifera) that substantially reduces the yield and quality of grape production in temperate and humid regions of the world. B. cinerea is a necrotrophic fungus that attacks the non-lignified aerial organs of grapes; in particular, berries are highly susceptible during ripening. The polycyclic nature and exponential progress exhibited by GM at the beginning of the its epidemic, as well as the abundant inoculum production, the high dissemination efficiency, the wide host range and the high genetic variability of B. cinerea, explain the difficulties encountered in attempting to control GM. At present, integrated disease management, including cultural and chemical control, is the... |

Pre- and post-harvest diseases restrict table grape production and exports (Vitis vinifera L.) in Chile, with the most important disease being grey mold (Botrytis cinérea). In addition, rot due to Aspergillus niger, Cladosporium herbarum, Penicillium expansum, and Rhizopus stolonifer frequently occurs. The pre- and post-infection activity of fungicides against these pathogens was studied on Thompson Seedless table grapes. Detached, mature, berries were used, and inoculations were performed with 20 µL of a 10(6) sporesmL-1 suspension placed on three punctures aseptically made at the calyx end of each berry. Fungicides used (per liter) were boscalid (600 mg), boscalid (200 mg) + pyraclostrobin (100 mg), boscalid (200 mg) + kresoxim methyl (100 mg),... |

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... |

Crown gall (Agrobacterium tumefaciens) and Phytophthora root and crown rot (PRCR), caused by P. cryptogea, are two major limiting factors affecting peach (Prunus pérsica) production in Chile. At present, Nemaguard is the most important rootstock used in peach orchards, and although several clonal rootstocks are under development worldwide, there is little information regarding their susceptibility to crown gall and PRCR. Therefore this investigation was undertaken to study the susceptibility to A. tumefaciens and P. cryptogea of the clonally propagated rootstocks Cadman®-Avimag (P. pérsica x P. davidiana), Mr.S 2/5 (P. cerasifera x P. spinosa), Viking ([P. pérsica x P. davidiana] x [P. dulcís 'Jordanolo'x P. blireiana]), and Nemaguard (P. pérsica x P.... |
