Identification and distribution of species of that cause blueberry stem blight in Chile.

Stem blight is a destructive woody disease of blueberry () caused by several species of the family Botryosphaeriaceae. A field survey was conducted in the mayor blueberry production area of Chile, comprising latitudes 32°49'S to 40°55'S, to determine the occurrence and distribution of Botryosphaeriaceae in the region. Together, a multilocus analysis, morphological characterization, and phytopathogenicity testing were used to identify 51 isolates belonging to (28 strains), (22 strains), and (1 strain).

Regulatory Frameworks for the Access and Use of Genetic Resources in Latin America.

The Nagoya Protocol is a legal framework focused on the Access and Benefit Sharing of genetic resources, including Biological Control Agents. In order to comply with the Nagoya Protocol, countries in Latin America are establishing legal frameworks for access to genetic resources. Scientists face the challenges of the bureaucratic and administrative burden to obtain the access permits to study the biodiversity present in Latin American countries, which include the evaluation of biological control agents that can be used in sustainable production programs.

First report of causing anthracnose fruit rot on in Chile.

Vaccinium corymbosum L. is the most cultivated blueberry species in Chile. Chilean fruits typically take up to 50 days to reach oversea markets; therefore, controlling post-harvest pathogens is of outmost importance to maintain international food safety and quality standards.

Silverleaf () Effects on Japanese Plum ().

Silverleaf is an important fungal trunk disease of fruit crops, such as Japanese plum (). It is known that infection by results in discolored wood, "silvered" foliage, and tree decline. However, effects on fruit yield and quality have not been assessed.

Antagonistic activity of endophytic actinobacteria from native potatoes (Solanum tuberosum subsp. tuberosum L.) against Pectobacterium carotovorum subsp. carotovorum and Pectobacterium atrosepticum.

Background: The native potatoes (Solanum tuberosum subsp. tuberosum L.) grown in Chile (Chiloé) represent a new, unexplored source of endophytes to find potential biological control agents for the prevention of bacterial diseases, like blackleg and soft rot, in potato crops.

First report of causing cankers and dieback in sweet cherry in Chile.

Sweet cherry () is one the most important fruit crops in Chile. Its production has significantly grown in recent years, reaching 228,448 tons exported in 2019/2020, to 47 countries. One of the main threats for this expanding crop are fungal pathogens, especially those that cause wood diseases.

First report of causing trunk disease in Chilean grapevines ().

Grapevine is one of the most important fruit crops in Chile and trunk diseases reduce the productivity, quality, and longevity of the vineyards. A survey was conducted in ancient (> 50 years) vineyards of Cauquenes (35°57´14´´S 72°17´07´´W) and Itata valleys (36°38´13´´S 72°30´57´´W), located in the central area of Chile, during 2019. Trunks and cordons showing dieback and dark brown to black wood discoloration were collected from 50 to 200-year-old plants of six cultivars: País, Moscatel, Torontel Amarilla, Carignan, Aliatica and Aligote.
