They combine rigorous scientific work, advanced human capital development, and specialized services for businesses and professionals, creating a direct bridge between academia and the productive sector.
Fruit Pathology Laboratory: detailed fruit tree health
El Fruit Pathology Laboratory The University of Talca's laboratory specializes in the comprehensive study of diseases affecting the main fruit crops grown in Chile and other temperate countries. This laboratory analyzes in depth the pathologies that damage these crops. apple trees, pear trees, cherry trees, European hazelnut trees, walnut trees, kiwis and grapevines, among others, with a strong emphasis on accurate diagnosis, understanding epidemiology, and designing effective control strategies.
An essential part of this laboratory's work involves research the causes and behavior of diseases that compromise fruit productivity and quality. This involves identifying the pathogens involved, studying how they spread, under what conditions they develop most intensely, and identifying the critical points in the crop cycle where intervention is most effective in reducing losses.
The laboratory team is characterized by a clear orientation towards sustainability in the sanitary management of fruit treesIt is not just about controlling diseases at any cost, but about doing so while minimizing environmental impact, risk to people, and the emergence of resistance in pathogens. Therefore, the evaluation of protection programs focuses on both conventional fungicides and biopesticides and innovative methods that allow reducing or eliminating sources of inoculum in the orchard.
Furthermore, the Fruit Pathology Laboratory plays an important role in the training of agronomy students and postgraduate studentsThese students participate in research projects, develop theses, and receive training in diagnostic techniques, pathogen isolation, molecular analysis, and control trials under laboratory, greenhouse, and field conditions. This blend of theory and practice prepares future professionals to face complex health challenges in modern fruit growing.
In parallel, the laboratory provides specialized services to the productive sectorThis includes phytopathological diagnoses, advice on sanitary management, characterization of emerging problems, and the design of control strategies adapted to the specific circumstances of each orchard. In this way, their work goes beyond scientific publications, reaching producers, technical advisors, and agricultural export companies directly.
Key lines of research in fruit tree pathology
One of the most prominent lines of research at the Fruit Pathology Laboratory is the study of Etiology, epidemiology and control of wood diseases In fruit trees. These pathologies, caused by fungal complexes that colonize the woody tissue, can generate progressive decline of the plants, death of branches and even the total death of the tree, severely affecting the productivity of high-value orchards.
Among the most researched families of fungi in this field are: Botryosphariaceae, Diaporthaceae and DiatrypaceaeThese include species capable of causing cankers, internal necrosis, and wood rot. The laboratory analyzes how infections occur, what agronomic and environmental factors favor their development, and what the best practices are for reducing the entry of these pathogens into fruit tree tissues.
Another line of work of great importance is the search and evaluation of native microorganisms with biocontrol potential for diseases in fruit crops. Within this framework, fungi of the genera are mainly studied. Trichoderma spp. and Clonostachys spp., as well as bacteria of the genus Bacillus spp., all of them recognized for their ability to antagonize pathogens, colonize roots or plant tissues and stimulate defense mechanisms in plants.
The selection process for these biological control agents involves isolating microorganisms from different environments associated with fruit crops, identifying the most promising strains, and carrying out antagonism and efficacy trials against pathogens of interest. Subsequently, its performance is evaluated under controlled conditions and at the orchard level, analyzing aspects such as persistence in the ecosystem, compatibility with other management practices and its effect on yield and fruit quality.
The laboratory also attaches great importance to the study of Etiology, epidemiology and control of postharvest diseases of fruits whose infection originates in the orchard, although the symptoms appear and develop strongly during storage, transport, or marketing. This approach is key for export fruit farming, where post-harvest life and product presentation are crucial.
Among the post-harvest pathogens investigated are Phlyctema vagabunda (associated, for example, with apple rot problems), species of Botrytis spp.fungi of the genus Alternaria spp. and bacteria such as Phytophthora syringaeamong other agents capable of damaging fruit during the marketing chain. The objective is to understand when and how infection occurs in the field, what cultural practices increase or decrease the risk of contamination, and what preventive measures can be applied before harvest to reduce subsequent damage.
In this context, the following are evaluated: integrated management strategies These methods combine good orchard practices, the rational use of fungicides, the incorporation of biocontrol agents, and hygiene measures during harvest and post-harvest stages. The ultimate goal is to ensure that the fruit reaches its destination markets with the best possible quality, reducing economic losses and preventing rejections due to health problems.
Food Safety Laboratory: training and services for the agri-food sector
Along with its focus on plant health, the University of Talca has the Food Safety LaboratoryA unit dedicated to ensuring that food produced, processed, or marketed meets the highest safety standards. This laboratory not only performs analyses and studies but is also strongly committed to... continuing education of the agri-food communityoffering specialized training to companies and professionals.
One of the most relevant characteristics of the Food Safety Laboratory is that it has training courses with SENCE codeThis allows organizations to access tax benefits to finance the training of their employees. These programs are primarily aimed at companies in the agribusiness, export, food processing, and related services sectors, as well as technicians and professionals who need to update their skills.
The training content provided covers key topics such as microbiology applied to foodThis knowledge allows us to understand the microorganisms that can affect food safety, the conditions that favor their growth, and the tools to control them. This microbiological foundation is essential for designing procedures that reduce the risk of contamination and maintain product safety throughout the food chain.
Another key area of ​​training is the good manufacturing practices (GPM)These courses are essential for any company that produces or handles food.
