Aminopyralid caused the highest phytotoxicity (50-75%), while dicamba caused less than 25% phytotoxicity. Aminopyralid also significantly reduced yield and thousand-grain weight to nearly zero, whereas the other treatments maintained yields of approximately 2,500 kg ha-1.

Photocatalysis can effectively degrade antibiotics, but the performance is greatly limited by the photogenerated carrier recombination in the photocatalytic material g-C3N5.

This study synthesized a Fe2O3/g-C3N5 heterojunction using the solvothermal method. The Z-scheme charge transfer mechanism facilitated efficient separation of photogenerated carriers, preserving photoelectrons and holes with high redox activity. This process generated a substantial amount of highly reactive free radicals such as ·O2- and ·OH, enabling the efficient degradation of tetracycline (TC). Under the optimal conditions of initial concentration of TC was 200 mg/L, the quality ratio of Fe2O3 and g-C3N5 was 1:2, the catalyst dosage was 50 mg and pH = 7.0, the TC degradation rate reached 92.46% within 60 min of visible light irradiation.

The herbicides atrazine (2.500 g a.i./ha), clethodim (96 g a.i./ha), fomesafen (250 g a.i./ha), and nicosulfuron (54 g a.i./ha) were applied when the plants were approximately 35 days after cutting. Visual assessments of herbicide-induced injury symptoms were conducted, along with measurements of the number of leaves, plant height, stem diameter, and total aerial part dry mass. When nicosulfuron was applied after emergence, it caused 60.0% damage 21 days after application (DAA), which changed the number of leaves, height, stem diameter, and total aerial part dry mass of hemp plants in a big way. Fomesafen caused 42.5% injury at 5 DAA, and atrazine caused 42.5% injury at 21 DAA, which may compromise the final yield.

In Brazil, the native tree Esenbeckia leiocarpa (guarantã) shows potential phytotoxic effects in weeds species. This study evaluates aqueous extracts from its aerial parts as a substitute for herbicides, focusing on their impact on weed germination and initial growth. The experiment used a completely randomized 7 × 4 factorial design with seven extract concentrations (0, 5, 10, 20, 40, 80, and 100%) and four weed species (Amaranthus hybridus, Bidens pilosa, Euphorbia heterophylla, and Digitaria insularis), with four replicates per treatment. Germination and germination speed index dropped significantly even at 5%, nearly ceasing at 20% or higher. The results indicate a non-linear dose-response relationship, suggesting that increasing the extract concentration beyond 20% does not result in a proportional reduction in germination. Pre-germinated seeds showed reduced radicle length and fresh mass from 5%, with E. heterophylla least affected and D. insularis most sensitive. Phytotoxic effects increased with concentration, except for D. insularis, where phytotoxicity stabilized (90% phytotoxicity) at concentrations above 20%. When applied to leaves, phytotoxicity was minimal, ranging from 5 to 10%, and had negligible effect on reducing fresh mass. The findings indicate that the response to E. leiocarpa leaf extract varies among the weed species evaluated, primarily affecting germination with minimal impact when applied to leaves. Thus, E. leiocarpa demonstrates potential as a bioherbicide for pre-emergent applications against the species studied.","PeriodicalId":15720,"journal":{"name":"Journal of Environmental Science and Health Part B-pesticides Food Contaminants and Agricultural Wastes","volume":" ","pages":"170-178"},"PeriodicalIF":1.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143677087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Mass spectroscopy, 1HNMR, and FTIR measurements confirm the Fmoc-Pro-Phe-OMe chemical structure. Studying electrochemical sensor characteristics, variation of scan rate parameters, and electrode surface area is crucial for understanding and optimizing the performance of modified and unmodified carbon paste electrodes. The FPPO/MCPE-modified carbon paste electrode has better sensing capabilities than the unmodified bare carbon paste electrode (BCPE). The FPPO/MCPE sensor has two linear ranges: 50-450 μM (CP) with a detection limit of 0.014 μM and 50-450 μM (FZ) with a detection limit of 0.015 μM. The FPPO/MCPE sensor is highly sensitive, measuring 4.25 µA/µM/cm2 for CP and 4.1 µA/µM/cm2 for FZ. Scan rate and concentration tests demonstrate that the oxidation of CP and FZ is a diffusion-controlled electrode process. The FPPO/MCPE sensor also demonstrates excellent repeatability, reproducibility, stability, and selectivity for detection of CP and FZ.

Results showed flumioxazin alone had variable efficacy, with high initial effectiveness but significant decline over time. In contrast, combinations such as flumioxazin + metribuzin and flumioxazin + diclosulam maintained high efficacy (>90%) throughout all periods. Flumioxazin + isoxaflutole was initially effective but diminished after 20 DAA. Combinations with herbicides of similar half-lives, like metribuzin, suggested synergistic effects, while pairings with longer half-life herbicides, like imazapic, complemented flumioxazin's action. Mixtures of flumioxazin with other herbicides effectively reduced weed dry mass, highlighting the advantage of herbicide combinations for sustained and efficient weed management in sugarcane cultivation.
