is the causal agent of green mold, a primary postharvest disease of citrus fruits. This study evaluated the efficacy of a novel photoactive chitosan-riboflavin bioconjugate (CH-RF) to control green mold in vitro and in lemon fruit. The results showed total inhibition of growth on APDA supplemented with CH-RF at 0.

Gray mold is the primary postharvest disease of 'Hayward' kiwifruit () in Chile, with a prevalence of 33.1% in 2016 and 7.1% in 2017.

Stem end rot (SER) caused by is the primary postharvest disease in the Chilean kiwifruit industry. Relationships between the postharvest occurrence of SER in 'Hayward' kiwifruit and the temporal dynamics of earlier colonization of the floral parts (petals, sepals, receptacles, styles) was studied in five orchards over two consecutive seasons in Chile. Weather conditions in the first season favored .

Background: The primary strategy to control powdery mildew in Chilean vineyards involves periodic fungicide spraying, which may lead to many environmental and human health risks. This study aimed to implement and evaluate the effectiveness and economic feasibility of a novel decision support strategy (DSS) to limit the number of treatments against this pathogen. An experiment was conducted between the 2010 and 2013 seasons in two irrigated vine fields, one containing a cultivar of Cabernet Sauvignon (CS) and the other a cultivar of Chardonnay (CH).

Synopsis of recent research by authors named "Hector Valdes-Gomez"

  • - Hector Valdes-Gomez’s research primarily focuses on postharvest diseases affecting fruits, with a notable emphasis on the control and management of pathogens such as green mold in lemons and stem end rot in kiwifruit.
  • - His studies highlight innovative approaches, including the use of chitosan-riboflavin bioconjugates for effective pathogen inhibition and the evaluation of decision support strategies to reduce fungicide usage in vineyards, thereby addressing both efficacy and environmental concerns.
  • - Through extensive field studies in Chile, Valdes-Gomez has identified relationships between preharvest conditions and postharvest disease prevalence, providing valuable insights for improving fruit quality and shelf life in the agricultural industry.
