Special Issue Information

Dear Colleagues,

Fruit and vegetable products are of great economic and nutritional importance, with high demand for their external and internal quality. However, they are susceptible to attack by pathogenic fungi, causing postharvest losses. This application of synthetic fungicides has been a strategy applied for a long time; however, they have caused alterations to the environment and problems of residuality, damage to health, as well as the generation of resistant strains. Alternatives to the use of fungicides for the control of pathogenic fungi have recently been presented. Basic substances are mentioned, such as those used in food or medicine, such as chitosan or organic and inorganic salts, plant extracts, essential oils, amino acids such as methionine or phenylalanine, GRAS substances, some yeasts and bacteria as biocontrols, and some others. The fungicidal effect at the in vitro level and the induction of defense mechanisms in fruits and vegetables have been reported. This Special Issue aims to highlight the importance of alternative treatments to the use of fungicides, aiming at a more sustainable, healthy, and synthetic pesticide-free world and reducing food waste and losses in postharvest worldwide.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Horticulturae is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Blueberry (Vaccinium corymbosum L.) is a crop with great potential for exportation and is very important for its antioxidant properties. However, this fruit is susceptible to different factors of deterioration and attack by pathogens. Botrytis cinerea is the main cause of post-harvest losses in this crop. Antagonistic yeasts from the Debaryomyces hansenii species, which is of marine origin, have been proposed as an alternative method for fungal control. For this reason, this study evaluated the in vitro and in vivo antagonistic capacity of the yeast against B. cinerea. The in vitro growth of the fungus was inhibited by 90% and germination was reduced by 100%, and through the production of volatile organic compounds, the growth of the pathogen was inhibited by 32.5%. Photographic evidence by electron microscopy revealed the effects caused by D. hansenii on B. cinerea. The incidence study showed a 50% reduction in the incidence of the disease caused by B. cinerea in blueberries, while quality parameters—such as soluble solids, titratable acidity, and pH—presented stable values, delaying the maturation process of the fruits. Likewise, the rate of reduction in firmness and physiological weight loss was lower, and the blueberries preserved their quality for a longer time. Full article
