Special Issue Information

Dear Colleagues,

Infectious plant diseases have historically caused severe agricultural losses and food insecurity. Significant events such as the Irish Potato Famine illustrate the devastating impact of plant pathogens on human societies. Advances in molecular biology, genomics, and plant pathology have improved our understanding and management of these diseases. However, new pathogens continue to emerge and existing ones evolve, exacerbated by climate change and global trade, thus presenting ongoing challenges to global food security and ecosystem health.

This Special Issue explores the latest research and innovations in combating plant diseases. We seek to cover a broad range of topics, including the identification of novel pathogens, advancements in diagnostic technologies, genetic and biotechnological approaches to enhancing disease resistance, and the influence of environmental changes on disease dynamics. By compiling cutting-edge research and expert insights, we aim to provide a comprehensive overview of the current challenges and future directions in plant protection.

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. Agronomy 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.

Tan spot (Pyrenophora tritici-repentis) and stripe rust (Puccinia striiformis f. sp. tritici) are major foliar diseases of wheat, causing significant yield losses globally. This study evaluated the efficacy of fungicide seed treatments in managing these diseases during early growth stages under greenhouse, growth chamber, and field conditions in the Northern Great Plains. Winter and spring wheat cultivars were treated with pyraclostrobin or combinations of thiamethoxam, difenoconazole, mefenoxam, fludioxonil, and sedaxane, among others. Greenhouse and growth chamber plants were inoculated with the respective pathogens, while field trials relied on natural inoculum. Fungicide treatments significantly reduced stripe rust severity (up to 36%) (p ≤ 0.05) and moderately reduced tan spot severity during early growth stages (15–20%). Treated plants demonstrated a 30–40% improvement in plant vigor, and a 25–50% increase in winter survival. Additionally, grain yield in treated plots increased by 25–50% (p ≤ 0.05), with test weight and protein content improving by 10% and 15%, respectively. These findings demonstrate the potential of fungicide seed treatments as an integrated pest (or pathogen) management (IPM) strategy to enhance early foliar disease control and wheat productivity.

Viral diseases are a frequent problem in the agricultural sector, causing significant economic losses, so their management is a constant challenge for producers and researchers. One of the factors that often complicates the control of viral diseases in plants is mixed infections, which occur when two or more viruses are present in a plant, generating a complex expression of symptoms. During a mixed infection, the following types of interactions basically occur: complementation and interference, the effect of which produces synergism, antagonism, or no effect. However, there are also subcategories of effects. This makes early detection difficult, and this infection can also give a competitive advantage to the pathogens involved. This review presents updated information on mixed viral infections in plants, the interaction categories, the severity of symptoms, and the impact on plants and vectors. The intention is to share information to better understand the etiology of the diseases. Full article
