  • Crop Allelopathy for Sustainable Weed Management in Agroecosystems: Knowing the Present with a View to the Future

    Sustainable weed management has become mandatory in the face of significant yield losses and the environmental pollution caused by the excessive use of synthetic herbicides.

    The researchers point out that allelopathy—the biochemical interaction between plants through the release of secondary metabolites—is gaining popularity as an eco-friendly alternative. Although many crops possess this potential, the study notes that farmers remain reluctant to apply this knowledge practically, highlighting a need to assist both advisors and farmers in implementing allelopathic strategies.

    According to the review, crops from various botanical families exhibit allelopathic properties and can be utilized through several flexible methods, such as crop rotation, intercropping, and the use of cover crops as living or dead mulches.

    The authors highlight that these tools are most effective when combined into an integrated weed management strategy. Furthermore, recent advances in chemistry are facilitating the production of bioherbicides, while biotechnologies like genetic engineering and stress induction can enhance or even introduce allelopathic traits in crops.

    Ultimately, the researchers recommend combining transgenic approaches with traditional allelopathic tools to maximize weed suppression, while emphasizing the urgent need for more field experiments using an integrated approach.

  • Allelopathy as a source of bioherbicides: Challenges and prospects for sustainable agriculture

    Balancing crop productivity with environmental sustainability is a primary global challenge, particularly as weeds develop resistance to synthetic herbicides and cause significant economic losses. Modern agriculture requires unconventional weed control strategies rooted in ecological principles to address environmental pollution and the depletion of natural resources.

    This research point out that allelopathy—a natural phenomenon where an organism produces biochemicals that influence the growth and survival of others—can be integrated into weed management plans. According to the study, this can be achieved by growing specific crops or applying extracts containing these compounds to significantly reduce the use of synthetic inputs.

    The review provides a comprehensive overview of the classification of allelochemicals and highlights recent advances in management practices and their underlying mechanisms. The authors argue that taking a holistic view of these chemicals supports an ecological approach to integrated weed control.

    Ultimately, the study suggests that this research contributes to future multidisciplinary programs, the development of chemoinformatic tools, and the application of new biotechnology methods in plant breeding.
