Special Issue Information

Dear Colleagues,

Weeds encompass invasive alien and range-expanding native plant species that may occur across a vast range of cultivated settings, from urban and urbanized areas to croplands and agroecosystems, or in natural areas affected by human activities. Primarily, weeds are a serious threat to agricultural crops and cultivated lands. Herbicide resistance is an emerging issue imperiling the global food production system as the number of weed species with herbicide resistance increases alarmingly worldwide. Biological knowledge and an understanding of weed ecology are essential for the application of proper and effective weed monitoring and management, while new approaches and novel strategies for weed control are urgently required in this era of climate change. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Herbicide resistance evolution
  • Herbicide resistance management
  • Weed biology and ecology
  • Alien plant invasions
  • Range-expanding native plants
  • Seed dormancy and germination
  • Allelopathy/Phytotoxicity
  • Precision herbicide application
  • Bioherbicides
  • Crop weed competition
  • Species-specific, site-specific and time-specific weed-related case-studies and emerging patterns
  • Weed diversity and abundance in temporal and spatial scales
  • Weed diversity and abundance in different cropping systems
  • Weed seed bank management
  • New approaches of weed management
  • Novel weed control tools
  • Weed-related issues, problems, challenges, and perspectives

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 semimonthly 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

The Unsung Champions of Evolution: Weeds and Their Management in Agricultural Systems

The history of weeds is closely intertwined with the development of agriculture. As early farmers began to select crops, weeds emerged as formidable competitors, evolving alongside them in a continuous struggle for survival. Over the past 23,000 years, while crops have been bred for human purposes, weeds have continuously adapted, thriving despite rigorous weed management practices. This coevolution highlights the remarkable ability of weeds to evolve rapidly, establishing them as true champions of adaptation. Herbicide resistance, in particular, exemplifies this phenomenon, with weeds developing both target-site resistance (TSR) through genetic mutations and non-target-site resistance (NTSR) through metabolic changes. Often, these mechanisms combine, resulting in heightened levels of resistance, especially within herbicide-resistant crop systems. The evolutionary success of weeds not only underscores their adaptability but also emphasizes their critical role in supporting biodiversity and ecosystem resilience, particularly in simplified agricultural landscapes. This chapter focuses on the evolution of weed management strategies and emphasizes the urgent need to transition to ecologically based weed management (E-bWM) approaches that balance productivity with sustainability, recognizing the ecological value of weeds in fostering resilient agricultural systems.

Weeds compete for environmental resources, leading to reduced soybean yield. In this context, integrated weed management strategies related to cultural control with the use of cover crops are necessary. Our aim was to evaluate weed occurrence in soybean systems with different cover crops. Field studies were conducted at Júlio de Castilhos, Santa Maria, Capão do Leão, Barra do Ribeiro, and Santo Ângelo, Rio Grande do Sul, Brazil. A randomized complete block design with four replications was used. Treatments consisted of black oats (Avena strigosa Schreb.), white oats (Avena sativa L.), rye (Secale cereale L.), hairy vetch (Vicia sativa L.), forage turnip (Raphanus sativus L.), and white clover (Trifolium repens L.) in pure stands or in mixtures. The analyzed variables were relative frequency, density, abundance, and importance value index, similarity index of weeds, dry shoot mass of cover crop, and soybean yield. Cover crops containing white or black oats reduced the relative importance value index of weeds, such as Lollium multiforum, Conyza spp., and Bidens pilosa. Forage turnip, hairy vetch, and white clover showed distinct responses. Black oats and forage turnip did not differ from cover crop mixtures in terms of dry shoot mass and grain yield, being superior to fallow, white clover, and hairy vetch. Full article
