ABSTRACT.- A simple and fast analytical method was developed and applied to assess the effect of two forms of zinc fertilization on a pecan tree cultivar in Uruguay: fertigation and foliar application with a specially formulated fertilizer. Zinc content was determined in 36 leaf samples from two crop cycles: 2020-2021 and 2021-2022. Fresh samples were dried, ground, and sieved. Analytical determinations were performed by flame atomic absorption spectrometry (FAAS, considered a standard method) and energy dispersive X-ray spectrometry (EDXRF, the proposed method). © 2025 by the authors.
In the last decade, the evolution of herbicide-resistant weeds, especially barnyardgrass (Echinochloa crus-galli (L.) Beauv.), to acetolactate synthetase (ALS) inhibitor herbicides, has accelerated. This research focused on the analysis of the new cultivars ACCase herbicide tolerance. Complete randomized blocks designed were used in two regions, using two new cultivars and early seeding dates.
ABSTRACT.- Among the most important sap-sucking insect pests (Hemiptera) of eucalypts are psyllids (Sternorrhyncha) and true bugs (Heteroptera). Damage inflicted to
trees by these insectsmay include significant leaf area loss, to weakening or tree death. High pest populations may affect a significant proportion of trees within commercial
stands, leading to large losses in forest productivity. Among the more than 400 species of Australian Hemiptera associated with eucalypts, eight psyllid species and
ABSTRACT.- Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by severe joint inflammation, synovial hyperplasia and degradation of the cartilage and bone in the joint. Patients with RA have an amplified T helper (Th) 1 and Th17 immune response and production of autoantibodies by autoreactive B cells. In the joint, macrophages mediate bone destruction and maintain the inflammatory process in RA.
ABSTRACT.- Ovine footrot has Dichelobacter nodosus as the primary pathogen, and it is characterized by its infectious and multifactorial nature, such as environmental conditions, management practices, and host susceptibility, leading to variable prevalence and economic impacts across regions. The present study investigated factors associated with footrot scores in individual sheep from a non-probabilistic sample of 60 flocks enrolled by the Uruguayan Wool Secretariat, from which 6,139 sheep had their feet clinically evaluated from 2021 to 2024. PCR was employed to confirm D.
ABSTRACT.- This study analyzed the impact of land use and cover changes, along with climate variability, on water consumption by quantifying actual evapotranspiration ((Formula presented.)) in the Tres Cruces River basin (TCR) in Uruguay. Using Landsat 8 and 9 images from 2014 to 2024, the SAFER method (Simple Algorithm for Evapotranspiration Retrieving), applied for the first time in Uruguay, estimated (Formula presented.) for natural vegetation (grasslands and riparian forests) and commercial afforestation areas.
In the original article [1], the omission of two critical references led to a shift in the citation numbering throughout the discussion section, which significantly impacts the interpretation of the text.
ABSTRACT.- Key message: Eight QTL conferring additive APR to YR were identified in wheat germplasm using GWAS. The high accuracy of GP models supports the feasibility of accelerating breeding for YR resistance. Abstract: Wheat yellow rust (YR), caused by Puccinia striiformis f. sp. tritici (Pst), is among the most devastating diseases affecting wheat worldwide. Since 2000, YR has expanded into regions where it was previously not considered an economically important disease. The deployment of YR-resistant cultivars remains the most effective and sustainable control strategy.
ABSTRACT.- Protists are one of the most diverse major eukaryotes in the soil ecosystems and play essential functional roles in shaping the microbial community structure, soil nutrient cycling, and crop productivity. However, protist community composition in soils is poorly understood, notably in paddy field soils with alternating oxic and anoxic phases and when under rotation with other crops and pastures. Furthermore, current knowledge about South American soils' protist communities is limited.
