Dear Colleagues,

Sustainable fruit production protects and broadens the interests of countries and contributes to the conservation of national treasures—the diversity of plant and animal species, humus content in the soil, etc. Following the guidelines for such farming, the use of agro-chemicals is minimized, the dependence on fuels is reduced, natural biological processes are enhanced, and soil fertility is restored.

Plant diseases nowadays are increasing due to the climate change we are witnessing, but also due to intensive plant production and technology. Similarly, infections are always higher in orchards with higher planting densities and where drastic pruning and abundant irrigation are present, like excessive nitrogen fertilization. Since the natural balance is disturbed under such production conditions, the plants’ vigor and resistance are reduced and various problems arise, like a large number of new diseases and their occurrence on a large scale. Under the current situation, plants become more susceptible to various diseases.

The importance of research on the proposed topic is based on the fact that there is an actual possibility of finding potential solutions to the struggle against pathogens of fruit trees that do not currently have adequate curative plant-protection remedies. Therefore, there is a need and necessity to find alternative natural ingredients and compounds in the fight against plant diseases. At the same time, effective antimicrobial, natural, and non-hazardous compounds are an alternative answer and an ecological solution to the problem of plant protection and could be a response to the increasing endangerment of human health.

In addition, the use and further development of organic plant-protection products will largely depend a) on the interest of the pesticide industries or the pharmaceutical industry (which is increasingly interested in this area, as alternative solutions to plant protection need to be pursued as registration and authorization of usage have been abolished for a large number of products); b) on the farmers' demands (which are growing over time); c) on the results of scientific research (which is increasing in that specific area); and d) on public opinion (which is more and more turning to so-called 'green' solutions).

Research on alternative compounds and agents in phytomedicine is not strongly represented in databases, as such research can be said to have just begun. This Special Issue deals with the innovative and original research on this topic nowadays.

Since science has an extremely important task in the introduction and development of any new technology, we also consider our task in fulfilling this purpose through this Special Issue.

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.
