Special Issue Information
Dear Colleagues,
Soilborne plant pathogens that cause root and crown rots, wilts, and damping-off are major yield-limiting factors in the production of horticultural crops. It is generally difficult to control soilborne pathogens since they stay deep in soil. Comprehensive approaches such as crop rotation, soil solarization, and the application of beneficial biological control microbes, resistant varieties, soil fumigants, etc., must be utilized to successfully control soilborne pathogens.
External organic amendments have traditionally been applied to improve soil health and fertility, but in some cases, plant disease suppression can also be observed. Prior research has demonstrated that the application of organic amendments can improve different aspects of soil and enable the control of soilborne pathogens.
Organic amendments to soil have been shown to assist in the development of suppressive features, which provide an environment in which plant disease development is reduced. This effect is related to the multiplication and diversification of microbial organisms after an organic input, which might play an important role in the functioning of plants by influencing their physiology and development and may effectively protect them against soilborne pathogens. The continuous development of new technologies for microbial community analysis has allowed a deeper understanding of the mechanisms and activities that soil microbes display under different conditions.
This Special Issue is therefore designed to synthesize up-to-date research on the benefits of using organic amendments that provide horticultural crops with protection against soilborne plant pathogens.

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.
