“…Upscaling the volumetric application of vinasse from 75 to 300 m 3 ·ha −1 increased the analytical concentration of residual TBT in the soil. Therefore, the higher the quantity of such an organic by-product in the system, the higher the availability of functional binding sites to retain such a reactive herbicide ( Trevisan et al, 2016 ; Mendes et al, 2021 ), decreasing its effective removal by M. pruriens .…”

“…Such an active compound represents one of the most significant phenylureas for application in intensive agricultural production systems. Tebuthiuron acts as a systemic, broad-spectrum photosystem II (PS II) inhibiting agent ( Mendes et al, 2021 ). Hence, it can suppress broad-leaf (e.g., Commelina benghalensis ) and grassy individuals (e.g., Urochloa decumbens , Digitaria horizontalis , and Panicum maximum ) by disrupting their photosynthetic activity ( Mendes et al, 2021 ).…”

Pesticides offer stakeholders cost-effective solutions to control weeds. Nevertheless, such active compounds can manifest as severe environmental pollutants when escaping from agroecosystems into surrounding natural ecosystems, driving the need to remediate them. We, hence, analyzed whether Mucuna pruriens can develop a potential phytoremediator for treating tebuthiuron (TBT) in soil with vinasse. We exposed M. pruriens to microenvironments containing tebuthiuron at 0.5, 1, 1.5, and 2 (standard dose) L ha−1 and vinasse at 75, 150 (industrial recommendation), and 300 m3·ha−1. Experimental units without organic compounds represented controls. We assessed M. pruriens for morphometrical features, such as plant height and stem diameter and shoot/root dry mass, over approximately 60 days. We obtained evidence for M. pruriens not effectively removing tebuthiuron from the terrestrial medium. Such a pesticide developed phytotoxicity, significantly limiting its germination and growth. The higher the dose, the more negatively the tebuthiuron impacted the plant. In addition, introducing vinasse into the system, irrespective of volume, intensified the damage to photosynthetic and non-photosynthetic structures. Equally important, its antagonist action further decreased the production and accumulation of biomass. As M. pruriens could not effectively extract tebuthiuron from the soil, it could allow neither Crotalaria juncea nor Lactuca sativa to grow on synthetic media containing residual pesticide. An atypical performance of such testing (tebuthiuron-sensitive) organisms over independent ecotoxicological bioassays validated inefficient phytoremediation. Hence, M. pruriens could not offer a functional remediative option to treat environmental pollution by tebuthiuron in agroecosystems where vinasse occurs, such as sugarcane-producing areas. Although M. pruriens considered a tebuthiuron phytoremediator as cited in the literature, satisfactory results did not occur in our research due to high concentrations of vinasse in the soil. Therefore, this information requires more specific studies about the influence of high concentrations of organic matter on M. pruriens productivity and phytoremediation performance.

“…Soil D significantly affected shoot dry matter due to its higher sorption capacity for tebuthiuron (Table 4). Notably, soil D, which had a higher SOC content (19.4 g dm -3 ) than the other soils and substantial clay content (58.6%) (Table 2), exhibited unique sorption characteristics, which is typical of non-ionic herbicides that rely on contact with the soil surface, primarily SOC and clay (Mendes et al, 2021).…”

“…Sorption and persistence are intertwined and dependent on herbicide properties, climate, and soil characteristics (El-Saeid & Alghamdi, 2020). The dynamics of tebuthiuron in the soil is mainly affected by clay and organic matter contents (Mendes et al, 2021); lower retention is observed in soils with lower clay and organic matter contents (Souza et al, 2001).…”

Applications of tebuthiuron can increase the risks of environmental contamination and hinder the cultivation of sensitive species in succession. The objective of this work was to assess the residual activity and sorption of the herbicide tebuthiuron in soils with different physical and chemical attributes. The experiments were conducted in a completely randomized design with four replicates. The experiment for determining residual activity was conducted in a 2 × 7 factorial arrangement consisted of two herbicide doses (0.6 and 1.2 kg a.i. [active ingredient] ha-1) and seven sowing times (0, 60, 120, 180, 240, 300, and 360 days after herbicide application) in sandy loam and sandy clay loam soils. The experiment for evaluating sorption was conducted in a sandy loam soil and two clay loam soils with applications of increasing tebuthiuron doses (0.025, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.50, 0.60, 0.70, and 0.80 kg a.i. ha-1). Regarding residual activity, the herbicide’s effect of the decreased over time, with no toxicity detected 360 days after application (DAA), regardless of the soils and doses used. Sandy loam soils had lower sorption, resulting in lower shoot dry weight and plant height and in higher phytotoxicity 21 days after emergence. Residual activity was detected 360 DAA in the studied soils. Tebuthiuron sorption was higher in soils with higher organic carbon and clay contents.

Herbicides play a crucial role in weed control in various agricultural and non-agricultural settings. However, their behavior in the environment is complex and influenced by multiple factors. Understanding their fate and retention, transport, and transformation is essential for effective herbicide management and minimizing their impact on ecosystems. This chapter begins by emphasizing the importance of studying herbicide behavior in real-world conditions, considering physical, chemical, and biological amendments in soil. It highlights how these amendments can directly affect weed control efficacy when residual herbicides are applied in pre-emergence. Detailed knowledge of herbicide behavior in the environment enables the adjustment of application rates based on soil type and climatic conditions, which is a key aspect of precision agriculture. The study of herbicide interactions in the environment has experienced significant growth across various subfields, particularly in the last three decades. It can be considered a multidisciplinary subject that encompasses areas such as agricultural, environmental, and biological sciences, as well as technology, physics, chemistry, and biomedicine. Overall, there are over 35,000 papers on herbicide behavior in the environment, and the trend indicates that the number of publications will continue to grow in the coming years.
