Special Issue Information

Dear Colleagues,

In recent years, the biological control of plant pathogens has been more and more emerged as a sustainable mean for disease management and it has been considered as a viable alternative for reducing the use of chemicals in agriculture. Actually, as a funding principle of IPM, it is promoted and encouraged by the EU Directive 128/2009 on Sustainable Use of Pesticides. The reasons for increasing restriction in the use of chemicals and for raising interest in biological control include the negative impacts of chemicals on human health and the environment, the pathogen-acquired resistance to commonly applied chemicals, and the lack of replacement products. The biological control involves the use of fungi, bacteria, yeasts, or viruses - usually known as biological control agents (BCAs) - that may suppress plant pathogens via multifaced modes of actions: from competition for nutrients and space to antibiosis, from parasitism to induced resistance in the host plant.

The aim of this Special Issue is to focus about the development, evaluation and use of these alternatives in order to increase the sustainability of disease management and to design novel approaches for disease control. We welcome contributions that present new products and microorganisms as well as innovative approaches able to prevent or suppress diseases. Increased knowledge and perspectives about how to optimize their use in sustainable and integrated strategies are also appreciated.

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. Agriculture 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 2600 CHF (Swiss Francs).

An alternative to chemical fungicides in post-harvest diseases are the use of biocontrol agents and their extracellular products against phytopathogens. Two relevant agents in post-harvest infections are Thielaviopsis paradoxa and Colletotrichum gloeosporioides, causing large economic losses in cacao, pineapple, and avocado during storage. In this work, we evaluated the effect of Wickerhamomyces anomalus, an effective biocontrol agent, against these filamentous fungi, focusing on the production of extracellular enzymes and their effect on fungal growth and germination. Moreover, we evaluated the use of inactivated fungal biomass as an inducer in complete (Potato Dextrose Agar and Yeast Peptone Dextrose) and minimal culture media. The antagonistic effect of W anomalus on the growth of both phytopathogens was also studied. The extracellular enzymes in YPD cultures, using T. paradoxa inactivated biomass as the best inducer, were capable of inhibiting the germination of both phytopathogens. In minimal media, only the production of a 30 kDa glucanase with activity against laminarin was observed. The enzyme was effective against the spore germination of T. paradoxa. In post-harvest crop protection tests, growth inhibition of T. paradoxa was observed using the cell-free enzyme extract, which is a promising system to protect cocoa fruits from T. paradoxa during post-harvest.
