Special Issue Information

Dear Colleagues,

In recent years, agriculture has faced significant challenges due to plant diseases, both in crops and post-harvest stages. Plant pathogens, such as fungi, bacteria, and viruses, can lead to substantial yield losses and poor-quality produce. These diseases are further exacerbated by over-reliance on chemical pesticides, which harm the environment, disrupt ecosystems, and contribute to the development of pesticide-resistant pathogens.

Microbial agents act through both direct and indirect mechanisms. Directly, they produce antifungal or antibacterial compounds that directly kill or inhibit the growth of pathogens. Indirectly, they can stimulate plant immune responses, enhance nutrient availability, or compete for space and resources, thus reducing pathogen colonization. Despite their potential, the development of microbial bioinoculants faces several challenges. Issues like product stability, consistency, and efficacy under various environmental conditions hinder their widespread use. Additionally, regulatory barriers and the cost of production complicate the commercialization of these biocontrol agents. However, continued research and technological advancements are essential to overcome these obstacles and integrate microbial biocontrol into modern agricultural practices.

This Special Issue will focus on the biological control of plant diseases, especially microbial agents. All types of articles, such as original research, opinions, and reviews, are welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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. Agriculture is an international peer-reviewed open access semimonthly 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 2600 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.

Post-harvest bacterial infections pose a serious threat to modern agriculture, resulting in substantial financial losses and environmental issues. Every year, microbial spoiling causes a significant loss in fruit and vegetable production, and traditional control techniques are frequently insufficient. This review highlights novel delivery systems such as edible films and coatings while analyzing recent developments in bacteriophage-based post-harvest disease management techniques. Bacterial resistance, environmental stability, and regulatory issues restrict the use of bacteriophages, despite their high specificity, biodegradability, and low environmental impact. Phage viability in storage and the field has increased thanks to developments in formulation technologies, such as encapsulation and stabilization. The review highlights the practical implementation of phage applications in post-harvest disease management, with a particular focus on innovative delivery systems as well as integrating legal and regulatory viewpoints. By bridging scientific innovation with legal and commercial considerations, this work offers an interdisciplinary foundation for advancing sustainable, phage-based approach. Full article
