Special Issue Information

Dear Colleagues,

Following the success of our first Special Issue of Agronomy, titled “Weed Biology and Ecology: Importance to Integrated Weed Management”, the Editorial Office is pleased to launch a second edition.

Weeds are plants that are inexorably associated with agricultural crops. Due to their pronounced survival and adaptive capacities, despite attempts to regulate their occurrence and regardless of the methods employed, they continue to persist in the environment.

However, climate change, alterations in tillage systems, changes in weed control and plant cultivation, and/or the introduction of new substances (inter alia, biostimulants) into plant cultivation practices have all had an impact on weed populations and their management. All these factors can affect weed growth and crop productivity in different ways. As such, understanding the potential behavior of weeds is an important aspect of tillage and plant cultivation that would aid farmers in making decisions pertaining to weed management.

This Special Issue therefore aims to present recent research findings concerning changes in the biology and ecology of weeds with regard to plant cultivation and climate change.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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 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.

The demand for sustainable weed management and the limited discovery of new herbicide molecules have led to high interest in plant-derived bioherbicides, such as the water residues (WRs) from the hydrodistillation of aromatic plants, which contain biologically active secondary metabolites. Here, the bioherbicidal activity of WRs of four aromatic plant species was investigated. Chemical composition of WRs was determined by solid-phase microextraction (SPME) coupled to gas chromatography–mass spectrometry (GC-MS), and their effect was assessed on seed germination and seedling growth characteristics of Avena sterilis, Echinochloa crus-galli, and Zea mays. Five concentrations, i.e., 0, 10, 20, 50, and 100% (v/v), with 100% representing pure WR, were tested. Phenolic monoterpenes dominate WRs in oregano and thyme, and oxygenated monoterpenes in laurel and lavender. Germination and growth responses were dose-dependent and species-specific. Oregano and lavender WRs exhibited the strongest inhibitory effect, reducing weed germination by 82% and 79%, respectively. In contrast, laurel extracts showed weaker germination inhibition. Across all tested species, germination delays were observed, making WRs a promising candidate for weed control. The results also showed that WR reduced root growth by up to 95% and shoot growth by 70–80%. Maize exhibited greater tolerance than the weed species, maintaining higher germination. Overall, WRs represent a promising tool for integrated weed management. Full article
