Special Issue Information

Dear Colleagues,

Soil-borne pathogens (SBPs) are microorganisms that live and thrive in soil and which possess the capacity to cause diseases in plants, animals, and humans. These pathogens have a major impact on agricultural productivity and food security as they can lead to significant crop losses and reduced yields. SBPs can be classified into several categories based on their properties and modes of infection, including bacteria, fungi, and nematodes. Their effects are highly pronounced under the harsh conditions of a climate in flux, especially drought conditions, as they add pressure on a disturbed root system to absorb enough water.

Bacterial soil-borne pathogens, such as Ralstonia solanacearum, can cause wilt disease in many crops, while fungal pathogens, such as Fusarium spp. and Pythium spp., can cause root and stem rots, damping off, and other diseases. Plant parasitic nematodes (PPNs) (e.g., Meloidogyne, Heterodera, and Pratylenchus spp.) are dangerous microorganisms that can feed on plant roots, leading to reduced plant vigor and yield.

SBPs are often difficult to manage, as they can persist in soil for long periods and can be spread through contaminated water, plant debris, or equipment. Integrated pest management (IPM) practices can help to reduce SBP populations, combining multiple management strategies to create a more sustainable and effective approach to pest control. These strategies include crop rotation, the use of resistant cultivars, soil fumigation, and biological control agents.

On the basis of this information, we highly encourage experts and researchers to contribute original scientific articles, reviews, and communications addressing the following topics:

  • Morphological and molecular characterization of soil borne pathogens;
  • Diversity patterns of soil borne pathogen populations;
  • Plant–microbiome interactions;
  • Management of soil borne 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. Pathogens 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 2700 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.

Vector-borne diseases pose a severe threat to human and animal health. Culex pipiens L. (Diptera: Culicidae) is a widespread mosquito species and serves as a vector for the transmission of infectious diseases such as West Nile disease and Lymphatic Filariasis. Synthetic insecticides have been the prime control method for many years to suppress Cx. pipiens populations. However, recently, the use of insecticides has begun to be questioned due to the detrimental impact on human health and the natural environment. Therefore, many authorities urge the development of eco-friendly control methods that are nontoxic to humans. The bacterial associates [Xenorhabdus and Photorhabdus spp. (Enterobacterales: Morganellaceae)] of entomopathogenic nematodes (EPNs) (Sterinernema spp. and Heterorhabditis spp.) (Rhabditida: Heterorhabditidae and Steinernematidae) are one of the green approaches to combat a variety of insect pests. In the present study, the mosquitocidal activity of the cell-free supernatants and cell suspension (4 × 107 cells mL−1) of four different symbiotic bacteria (Xenorhabdus nematophila, X. bovienii, X. budapestensis, and P. luminescens subsp. kayaii) was assessed against different development stages of Cx. pipiens (The 1st/2nd and 3rd/4th instar larvae and pupa) under laboratory conditions. The bacterial symbionts were able to kill all the development stages with varying levels of mortality. The 1st/2nd instar larvae exhibited the highest susceptibility to the cell-free supernatants and cell suspensions of symbiotic bacteria and the efficacy of the cell-free supernatants and cell suspensions gradually declined with increasing phases of growth. The highest effectiveness was achieved by the X. bovienii KCS-4S strain inducing 95% mortality to the 1st/2nd instar larvae. The results indicate that tested bacterial symbionts have great potential as an eco-friendly alternative to insecticides. Full article
