Special Issue Information

Dear Colleagues,

Biotic stresses are responsible for important crop losses each year. Downy mildews, elicited by obligate pathogens of the oomycete Peronosporaceae family, are recognized as an increasing threat for crop production. The disease can cause economically significant damage in different crops, reducing yield and severely compromising the quality of marketable products. Downy mildew disease is more severe in temperate climates, during mild or fresh seasons, and high air humidity. It is a polycyclic foliar disease, easily disseminated by airborne conidia dispersed by wind. The pathogens can survive as oospores in infected plant debris in the soil and leaves, and these are responsible for the primary infections. Research articles will update our understanding of the most important advances in research on downy mildew disease across a broad range of subjects, such as disease resistance, genetics, germplasm and breeding, crop protection, phenotyping, plant biology and ecology, pathology, mycology, and taxonomy in different crops species including vegetable crops, ornamental, and field crops. 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 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). 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.

The oomycete Plasmopara viticola, which causes downy mildew, is currently one of the most destructive pathogens affecting grape production. Although native to the eastern United States, P. viticola was introduced into Europe in the mid-to-late 1800s and is now found in virtually every grape-growing region of the world. Since its discovery, much effort has been made to understand the life cycle and infection process of the pathogen to develop more effective management practices. Widespread application of fungicides, especially those which have only one mode of action, has led to an increased occurrence of resistance to these treatments. Thus, with increased fungicide resistance and rising environmental concerns surrounding their use, traditional chemical management practices have begun to fall out of favor. Newer approaches, from targeted breeding utilizing quantitative trait loci to biological control agents, are continually being investigated and adapted to limit the damage caused by downy mildew. This review summarizes the current knowledge of the pathogen and methods of its control and explores potential avenues for future research focused on hypovirulence and biological control agents.
