Dear Colleagues,

The advent of chemical herbicides has propelled agriculture in the modern era, helping producers manage weeds in a simple and efficient manner. These compounds have been used extensively and have triggered a world revolution, increasing the agricultural productivity. It is precisely due to their broad usage and high effectiveness, exerting high selective pressure, that herbicides promoted the evolution of resistant weeds. The continuous use of herbicides as lead to a steady increase in the number of herbicide-resistant biotypes in the past decades. Multiple and often complex resistance has risen, challenging producers with limited control options. Cultural practices must be adapted to protect chemical weed control tools.

In this Special Issue, we welcome reports and research results on the molecular characterization of herbicide resistant weeds. Topics may cover but are not limited to:

• Characterization of herbicide-resistant weeds, weed populations, description of resistance-conferring mechanisms and the development of genetic tests
• Geographical maps of resistant weed populations and the promotion of agronomic best-practices (e.g., early detection and management) with molecular diagnostics of resistance
• New methods and examples of weed detection based on molecular tools
• Studies describing the phenotypic, genetic or genomic impact imposed by selective pressure in the evolution of resistance
• Similarities and differences between herbicides, fungicides and insecticides resistance mechanisms and diagnostic tools

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.
