Published: October 2019

Objetivo: comparar el grosor óseo palatino bilateral e identificar zonas seguras para inserción de miniimplantes. Métodos: se llevó a cabo un estudio transversal que incluyó 100 tomografías de haz cónico (CBCT) pretratamiento de pacientes que asistieron a la Especialidad de Ortodoncia en la Universidad Autónoma de Nayarit (UAN). Las imágenes fueron orientadas utilizando el mismo protocolo. En el corte sagital, las mediciones se realizaron de los 0 a los 24mm, con intervalos de 3mm entre cada una, con la primera medición en el borde posterior del foramen incisivo. Las mediciones del grosor palatino se realizaron en el corte coronal a los 2, 4, 6 y 8mm de la sutura media palatina hacia ambos lados. Resultados: se encontró mayor grosor en la zona anterior en las medidas sagitales de 0 mm y 3 mm, a diferencia del resto del paladar. Se hallaron diferencias estadísticamente significativas al comparar los valores tanto sagitales como transversales. Con la prueba Post Hoc de Tukey no se encontraron diferencias estadísticamente significativas al comparar el lado derecho con el izquierdo en cada una de las medidas transversales. Conclusiones: no se encontraron diferencias significativas entre los dos lados, se determinó como zona segura la región anterior del paladar de 0mm a 6mm y es primordial la CBCT en todos los pacientes con indicación de miniimplantes en paladar.

Published: October 2019

RESUMO Objetivo: avaliar a influência da mobilização da flexura esplênica nos principais resultados cirúrgicos de pacientes submetidos à ressecção de câncer do cólon sigmoide ou reto. Métodos: os bancos de dados MEDLINE, Cochrane Central Register de Ensaios Controlados e LILACS foram pesquisados usando os termos "mobilização da flexura esplênica", "cirurgia colorretal", "câncer retal", "ressecção anterior", "câncer de cólon sigmoide", "ressecção de sigmoide". O desfecho principal foi a deiscência da anastomose. Outros desfechos analisados foram mortalidade, sangramento, infecção e complicações gerais. Os tamanhos dos efeitos foram estimados por meio do agrupamento dos dados de seis estudos de caso-controle (1.433 pacientes) publicados até janeiro de 2018. Resultados: nossa meta-análise revelou que pacientes submetidos à mobilização completa da flexura esplênica tinham um risco maior de deiscência anastomótica (RR=2,27, IC95%: 1,22-4,23) em comparação àqueles não submetidos a esse procedimento. Nenhuma diferença pôde ser demonstrada entre os grupos em termos de mortalidade, sangramento, infecção e complicações gerais. Conclusão: a mobilização da flexura esplênica está associada a um maior risco de deiscência anastomótica nas ressecções de câncer de reto ou cólon sigmoide. Esta manobra cirúrgica deve ser utilizada com cautela no manejo cirúrgico dos tumores colorretais.

ABSTRACT Objective Analyzing the prevalence of metabolic syndrome and its association with adolescent diet quality. Methods Cross-sectional research with 327 adolescents from public and private high schools of Teresina, Piauí. Socioeconomic, anthropometric, and food consumption data were analyzed to obtain the Brazilian Healthy Eating Index-Revised. Moreover, data related to metabolic syndrome (blood glucose, blood pressure, waist circumference, triglycerides, and high-density lipoprotein cholesterol) were also analyzed. Continuous variables were described by means, standard deviations, and 95% confi dence intervals. To verify the association between dependent and explanatory variables, we calculated the adjusted odds ratio. The level of signifi cance was set at p<0.05. Results The prevalence of metabolic syndrome was 3.3%, with low high-density lipoprotein cholesterol concentration being the most frequent alteration (50.5%). The mean score on the Brazilian Healthy Eating Index-Revised was 55.4 points. The worst scores were obtained in whole cereals, dark-green and orange vegetables, oils, milk and dairy products, and whole fruits. In contrast, total cereals, meat, eggs, and legumes had scores close to the maximum stipulated. The lowest tertile of dark-green, orange, and leguminous vegetables showed risk for low high-density lipoprotein cholesterol, and the second tertile was protective against high blood glucose levels. As for the milk group, its lower intake increased the chances for high triglyceride and blood pressure levels. Conclusion Despite the low prevalence of metabolic syndrome, there were significant alterations in its components,associated with less consumption of important Brazilian Healthy Eating Index-Revised items.

RESUMO Objetivo avaliar os diferentes componentes da resistência do sistema respiratório e a força muscular respiratória, bem como investigar a ocorrência de limitação de fluxo expiratório (LFE) de pacientes obesos mórbidos (OM) na posição sentada. Métodos a amostra foi composta de OM (IMC ≥ 40 kg/m2) e de indivíduos não obesos (NO) com IMC entre 18 e 30 kg/m2. O protocolo foi composto de: avaliação antropométrica e da função respiratória (espirometria, pressões inspiratória (PIM) e expiratória máximas (PEM) e oscilometria de impulso). Na comparação entre os grupos, foi utilizado o teste T para amostras não pareadas. As correlações foram avaliadas pelo teste de Pearson, e o nível de significância foi de 5%. Resultados Foram avaliados 50 OM (idade 40,0 ± 10,4 anos, 1,64 ± 0,09 m, 138,8 ± 33,6 kg e 50,7 ± 8,9 kg/m2), além de 30 NO (idade 37,6 ± 11,5 anos, 1,67 ± 0,09 m, 65,2 ± 10,3 kg e 23,2 ± 22 kg/m2). Os OM apresentaram maiores valores de resistência total, central, de vias aéreas, tecidual e periférica quando comparados aos NO. Nenhum paciente apresentou LFE. A circunferência abdominal se associou com variáveis espirométricas PIM e PEM. A relação cintura-quadril se correlacionou com variáveis de mecânica respiratória, além das espirométricas PIM e PEM. Conclusões pacientes com obesidade mórbida e sem padrão espirométrico obstrutivo apresentam aumento nas resistências total, de vias aéreas, periférica e tecidual do sistema respiratório quando comparados a não obesos. Esses indivíduos, entretanto, não apresentam limitação de fluxo expiratório e redução da força muscular respiratória.

Published: October 2019

Abstract The aim of the present study was to quantify the physical demand in terms ofdistance covered and to verify the relation with technical performance during simulated futsal matches of U-19 category. Sixteen players participated in the study. Two simulated matches were performed, and the physical demand was quantified by the total distance covered, distance covered per minute and distance at different intensities. In addition, technical performance variables were analyzed during matches. The total distance covered was, on average, 3259.97 ± 180.27 m, with 113.26 ± 6.11 m / min. Approximately 26% of the total distance was covered at high intensity (i.e.,> 15 km.h-1), with significant decrease of these actions in the second half of matches (p <0.05). There were no significant correlations between physical and technical performance variables. However, there were positive correlations classified as “strong” of technical variable “unsuccessful kicks” with the total distance covered during match. This study demonstrated that simulated futsal matches of the U-19 category present high physical demand, with values of distance covered per minute at different intensities similar to those found in professional Brazilian players during official matches. There were no significant correlations between physical and technical performance during matches; however, correlations classified as“strong” between unsuccessful kicks were obtained with total distance covered (r=0.51; p=0.06), distance covered at high intensity (r=0.51; p=0.09) and with distance covered in sprints (r=0.56; p=0.06), suggesting that the efficacy of kicks is influenced by the match intensity.

Published: October 2019

Abstract The present study examined the changes in developmental assets among young basketball players during a 4-month competitive period, accounting for variation by age group. Additionally, we examined the age-related variation on developmental assets. Sixty-five adolescent basketball players aged between 9.5 to 17.3 years were considered. We used the Portuguese version of the Developmental Assets Profile Questionnaire. Multilevel modeling was used to estimate the magnitude of changes on developmental assets across the 4-month competitive season, as well as aligning assets scores by chronological age. Positive values and positive identity scores were substantially increased after the 4-month competitive sample. The other assets scores showed no variation across the competitive 4-month competitive season, independent of age group. There was a trend of linear decrease in developmental assets as the adolescent players got older. For positive values, there was a non-linear trend with a higher decrease rate between about 10 to 14 years, levelling off thereafter. Developmental assets did not appear to be influenced by exposure to a period of organized training and competition among adolescent basketball players. Hence, the observed decrease on developmental assets when aligning by age may reflect the influence of contextual and cultural environments of practice. This is of particularly interest for positive values, which refer to school engagement or and social justice, qualities that are not sport-specific but assume a key and importance position in sport participation for a positive role in youth development.

Abstract Considering agility is a prerequisite for basketball performance and several agility tests have been used during the pre-draft assessment of the National Basketball Association (NBA), the aimed of this study was to examine the associations between pre-draft athletes´ performance scores in NBA draft combine testing protocol. The performance of 480 athletes invited to the NBA pre-draft assessment from 2010 to 2017 was considered. Tests in the NBA Draft Combine considered in this study included the Shuttle Run Test, Lane Agility Test, Sprint Test, and Jump Test (standing vertical leap). Zero order correlations were calculated to examine the associations between performance tests by fitting Bayesian linear regression models. Among running testing, both Shuttle Run Test [r=0.45, 95% confidence interval (CI) 0.34 to 0.56) and Sprint Test (r=0.45, 95% CI 0.37 to 0.54) were moderately associated with the Lane Agility Test. The association between the Sprint Test and Shuttle Run Test was moderate at best (r=0.27, 95% CI 0.16 to 0.38). Correlations between Jump Test and running tests were moderate to large, ranging from -0.51 to -0.19 (Lane Agility Test: r=-0.33, 95% CI -0.42 to -0.24; Shuttle Run Test: r=-0.19, 95% CI -0.31 to -0.07; Sprint Test: r=-0.51, 95% CI -0.59 to -0.43). As a conclusion, we found a moderate to large correlations between the tests performance of the NBA Draft Combine, implying that the overall procedures may provide in part overlapping information about basketball maximal short term performance.

Abstract It is necessary to clarify if BM and track and field performance can modulate the perception about RPE-session. The purpose of the present study was to verify if biological maturity and track and field-specific performance can be associated with training load (RPE-session method). Seventy-five young athletes (13-15 years old) of both genders participated in the present study. The experimental protocol lasted seven consecutive days. Performance tests (75-m running, long jump, 250-m running, shot put and 1000-m running) were made on the first day. After 48 hours, five days of track and field training it was prescribed, each day represents a training of each performance test. All training sessions had the same duration (120 min). The value of the training load was obtained multiplying the RPE value with training session duration (in minutes). For girls, the training load of 250-m training was correlated with biological maturity (r = -0.36, p = 0.02, n = 37) and specific performance (r = 0.33, p = 0.04, n = 37). All other analyzes indicate that biological maturity and track and field-specific performance do not influence the training load based on RPE-session method. Training load based on RPE-session is not influenced by biological maturity and track and field-specific performance, therefore can be used to control the training load of young track and field athletes. To girls it is necessary a care to control the training sessions intensity of 250-m running.

Authors: Melo Geovana Ferreira , Campos Vanessa T. Bueno
Published: October 2019

Abstract This study aims to highlight the need for developing institutional projects on University Pedagogy which contribute to the professional development of higher education teachers at work. We questioned them the possible contributions of training activities focused on teaching development and professional identity. This quantitative, qualitative research was conducted in a federal university located in the region of Triângulo Mineiro, in Brazil, from 2013 to 2016. We collected data by means of questionnaires and interviews with university professors. We concluded that fragmented, sporadic training processes contribute little to professional development. Thus, in view of the complex work in higher education, institutional efforts are needed to consolidate a University Pedagogy as a permanent field for teacher training and development.

Published: October 2019

Abstract The aim of this article is to identify and analyze the deployment of the higher education policies directed at the training of Brazilian Sign Language teachers in the upcoming decade, under decree 5.626 from 2005. Documentary research, based on content analysis, allowed the outlining of a panorama of the courses offered at federal higher education institutions in Bilingual Pedagogy and a Degree in Libras, from 2006 to 2015. The results revealed that the distance learning modality was the main one linked to the expansion of the number of vacancies. However, in a general estimate, there is still a small number of vacancies and higher education courses for these professionals, especially in the segment that includes early childhood education and the first years of elementary school. This shows the lack of graduates from these courses, in the national scenario.

Published: October 2019

Resumo Para que ocorra o controle de doenças na pós-colheita de uvas, são utilizados agroquímicos que, apesar de eficientes, podem causar problemas à saúde humana. Neste sentido, o presente trabalho tem o objetivo de verificar o potencial dos compostos voláteis presentes no óleo essencial de pitanga (OEP), guaçatonga (OEG) e melaleuca (OEM) no controle de Botrytis cinerea tanto in vitro quanto inoculados nas bagas de uvas ‘Rubi’, bem como verificar a indução de resistência nesses frutos. Dessa forma, avaliou-se o crescimento micelial do B. cinerea, o controle do mofo cinzento nas uvas ‘Rubi’, a qualidade pós-colheita dessas bagas e a atividade das enzimas polifenoloxidase (PPO), fenilalanina amônio liase (PAL), glucanase (GLU) e quitinase. De acordo com os resultados, observou-se que os compostos voláteis liberados pelos óleos essenciais reduziram os índices de velocidade de crescimento micelial de B. cinerea e da doença do mofo cinzento. Os tratamentos com voláteis de OEP e OEG ativaram mecanismos de indução de resistência desses frutos. Dessa forma, ressalta-se que OEP e OEG liberam compostos que apresentam a capacidade de agir diretamente sobre B. cinerea e também induzem a resistência de uvas ‘Rubi’, reduzindo o mofo cinzento nessas uvas.

Published: October 2019

Abstract Sugarcane bagasse from agro-industrial residues was autoclaved at 121 °C for 15 min, treated with 2% NaOH and activated with 2.5% glutaraldehyde for the immobilization of soybean β-glucosidase. Scanning electron microscopy, energy dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy characterized and confirmed the immobilization of the β-glucosidase on the sugarcane bagasse. The immobilization efficiency was influenced by the type of bagasse modification and was 99% at maximum. The optimum immobilization conditions were 1 mg mL-1 protein, pH 7.0, 2.5% glutaraldehyde, 110 rpm and 8 h of incubation at 4 °C. The immobilized system could be reused for 15 cycles without the complete loss of activity. The thermal stability indicated a residual activity of 15% after 180 min incubation at 70 °C. The conversion efficiency of glucosides to aglycones in commercial soymilk by β-glucosidase immobilized on sugarcane bagasse was evaluated and the total aglycone content increased by 23.8% after incubation at 50 °C for 120 min.

Published: October 2019

Abstract Objectives: To translate and back-translate the Autism Diagnostic Observation Schedule (ADOS) into Brazilian Portuguese, to assess its cross-cultural semantic equivalence, and to verify indicators of quality of the final version by analyzing the inter-rater reliability of the ADOS scores. Methods: This study had three stages: 1) translation and back-translation; 2) semantic equivalence analysis; and 3) pre-test to verify the agreement between mental health specialists and an ADOS senior examiner regarding the scoring procedure. Authorization to translate and carry out the cultural adaptation of the instrument was first obtained from the Western Psychological Services, publishers of the instrument. Results: The main preliminary results pointed to good equivalence between the original English version and the final version and the Brazilian version following the cultural adaptation process. Some semantic differences were found between the original version and the back-translation into English, but they did not interfere with the first translation into Portuguese or into the final version. One of the limitations of the study was the small sample size; for that reason, the inter-rater reliability of the ADOS scores between the specialists and the senior examiner using the kappa coefficient was adequate for 7 out of 10 areas. Conclusions: We conclude that the creation of an official Brazilian version of ADOS will help to strengthen clinical and scientific research into ASD, and deter the use of other unauthorized versions of ADOS in the country.

Published: October 2019

Abstract Introduction: Intimate partner domestic violence against women causes physical and psychological harm to victims. The relevance of this topic is indisputable and there is a need to identify in greater detail how these women experience violence, since these factors have considerable clinical implications. Objective: To develop a Portuguese version of the Module for Assessment of Domestic Violence, adapted from Axis I of the Operationalized Psychodynamic Diagnosis (OPD-2), considering content validity and psychometric characteristics. Method: Cross-cultural adaptation was based on guidelines for the process of cross-cultural adaptation of self-report measures. OPD clinical interviews were recorded and transcribed. These interviews were analyzed by two independent judges trained in the OPD-2. Results: The sample comprised 56 women who had been victims of domestic violence, with a mean age of 30.07 years (standard deviation = 9.65). The adapted version has content validity and good psychometric characteristics. Evaluation of semantic equivalence took into account the psychodynamic references, using the same ideas as the original instrument. Interexaminer reliability between the judges was substantial (k = 0.63) and Cronbach's alpha for the new version indicates good reliability. Conclusion: The OPD-2 offers a psychodynamic diagnosis of the victim that complements traditional nosological diagnosis, particularly in the context of domestic violence with the adaptation of Axis I. Certain biases could have been detrimental to aspects of this study, but they were controlled. The study objective was achieved and the Module was successfully adapted to Brazilian Portuguese. The results are in line with those of the original study.
General aspects of quality of life in heterogeneous populations: notes on Flanagan's Quality of Life Scale (QoLS)
Authors: Zucoloto Miriane Lucindo , Martinez Edson Zangiacomi
Published: October 2019

Abstract Introduction: Instruments aimed to investigate general aspects of quality of life are scarce in the literature. Flanagan's Quality of Life Scale (QoLS) is an alternative instrument which provides a more comprehensive evaluation of quality of life in different contexts. Objective: To investigate some psychometric properties of the QoLS and discuss the measurement of quality of life using this scale in heterogeneous and large populations. Methods: The QoLS comprises 16 items divided into five dimensions. Responses were measured using a 7-point rating scale. Data were collected from a stratified sample of primary health care users in the municipality of Ribeirão Preto, state of São Paulo, Brazil. Polychoric correlation matrix and exploratory and confirmatory factor analyses were performed. Results: A total of 1,054 primary health care users in 12 health care facilities were interviewed: 79.7% female; mean age = 36.97 years (standard deviation = 15.1). Moderate to low correlation coefficients were observed between almost all pairs of QoLS items. Items 7 and 9 as well as items 14 and 15 were the pairs presenting the highest correlation coefficient. The original structure of the QoLS, with five dimensions, showed adequate psychometric properties regarding the data collected. The inclusion of a single item on life satisfaction was proposed. Conclusion: The original structure of the QoLS was validated and found to be reliable when applied to primary health care users. A new general item was suggested for future studies to improve the interpretations and associations regarding general aspects of quality of life in large and heterogeneous populations.
Uncertainty estimation in hydrodynamic modeling using Bayesian techniques
Authors: Pinheiro Viviane Borda , Naghettini Mauro , Palmier Luiz Rafael
Published: October 2019

ABSTRACT Uncertainty estimation analysis has emerged as a fundamental study to understand the effects of errors inherent to hydrodynamic modeling processes, of aleatory and epistemic nature, due to input data such as discharge, topography and bathymetry, to the structure and parameterization of the mathematical models used and to their necessary boundary and initial conditions. The study reported in this paper sought to apply a Bayesian-based methodology, associated with thousands of Markov Chain Monte Carlo simulations, in order to identify and quantify the uncertainty related to the Manning’s n roughness coefficient in a 1D hydrodynamic model and the total uncertainty involved in the prediction of hydrographs and water surface elevation profiles resulting from flood routing through a reach located in the upper São Francisco river, between the Abaeté river outlet and the town of Pirapora. The results show that the Bayesian scheme allowed an adequate posterior identification of the parametric uncertainties and of those associated to other sources of errors, with important changes in the prior probability distributions. In addition, the residuals analysis corroborates the applicability of the method to the analysis of uncertainties in hydrodynamic modeling through the use of a more flexible likelihood function than the classical one based on the hypotheses of normality, homoscedasticity and uncorrelated residuals. Future work includes the sensitivity evaluation of the posterior distributions to the addition of lateral inflows, especially concerning the residuals serial correlation, as well as the adoption of other variables to update the prior uncertainties, and the validation of the methodology through the use of the posterior distributions to estimate the total uncertainty involved in the prediction of floods other than the ones used in the inference process.

ABSTRACT: This study evaluated the relative competitiveness of two common bean cultivars in coexistence with volunteer corn emerging at different times in different proportions of plants in the association. Firstly, for both beans and volunteer corn, the plant population was determined in which the final production of dry biomass becomes constant (24 plants pot-1). A completely randomized experiment design, with five replicates, was carried out in a 2×2×5 factorial scheme, involving two common bean cultivars (IPR Gralha and Fepagro Triunfo), two emergence times of volunteer corn plants (-7 and 0 days in relation to beans) and five proportions of plants in the association (100:0, 75:25, 50:50, 25:75 and 0:100). At 35 days after bean emergence, measurements of plant height, leaf area and dry biomass of the aerial part of both species were measured. The competitiveness analysis was evaluated through diagrams applied to substitutive experiments and the use of relative competitiveness indices. The height of bean cultivars is reduced when volunteer corn emerges at the highest proportions and in advance. Early emergence of volunteer corn reduces leaf area from both bean cultivars while simultaneous emergence only reduces the leaf area of Triunfo. The dry matter biomass is lowered, due to the competition of the corn emerged before the bean, and the cultivar Gralha is more tolerant. In this way, the importance of the bean sowing in an area free from infestation of volunteer corn plants is verified.

ABSTRACT: The presence of volunteer corn plants in coexistence with soybean has been increasing since the introduction of glyphosate-resistant corn hybrids. This study aimed to evaluate the effect of interference of volunteer RR® corn plants at different densities on two RR® soybean cultivars. The experiment was conducted in Rio Verde, GO. The experimental design was a randomized block design in a factorial arrangement (2×5), with four replications. Factor A consisted of two soybean cultivars (BMX Potência RR® and M8210 IPRO®), while five densities of RR® corn plants per m2 (0, 4, 8, 12, and 16) were adopted for factor B. The following evaluations were carried out for soybean: plant height, SPAD index, percentage of interrow closure, shoot dry matter, first pod height, number of pods per plant, 100 grain weight, and grain yield of grains. Soybean plant height presented a linear and positive relationship with the increased density of corn plants. Shoot dry matter, 100 grain weight, number of pods per plant, and grain yield were negatively affected by the increased density of volunteer corn infestation. The soybean cultivar M8210 IPRO® was more susceptible to corn plant interference when compared to the cultivar BMX Potência RR®.

ABSTRACT: The recognized allelopathic activity of oats as a soil-cover plant induces the study of the potential of their germplasm. The objective of this study is to verify if there is genotype variability in the Avena spp. with regard to allelopathic activity. Extracts of A. strigosa ‘Agro Quaraí’, ‘Agro Esteio’, ‘Embrapa139’, ‘AF 12104’, ‘AF 12109’, ‘AF 12202’, ‘AF 12209’, A. sativa ‘UPFPS Farroupilha’ and ‘AF 1345 Ucraniana,’ were prepared in three concentrations w/v (5 g, 10 g, and 20 g of dry mass 100 mL-1). The experiment was conducted in a germination chamber for 15 days, with lettuce (Lactuca sativa L.) as the recipient plant. There was complete inhibition of germination under 20% w/v extracts and partial inhibition at 10% w/v. Only 5% w/v observed a difference between the genotypes, in which the highest efficiency was obtained from the extracts of white oats and black oats ‘AF 12104’ and ‘Agro Quaraí’, which reduced germination between 92% and 97%. When the concentration increased above 5% w/v the harmful effect on germination was significantly greater. Only in extracts at 5% w/v there was a higher genotypic effect on germination, with variation in the germination rate index, root, and hypocotyl stretching. The genotype that had the least allelopathic effect was AF 12202, with an inhibitory mean in the evaluated attributes of 35%. The other genotypes inhibited the attributes of germination and seedling growth between 66% and 86%. With regard to the variability in the Avenaspp., the allelopathic activity could be applied to obtain cultivars with greater weed suppressive power.

ABSTRACT: The efficacy of imazamox to control Eichhornia crassipes with a centrifugal energy spray nozzle at doses and volumes of spray solution and the costs of mechanical and chemical control of aquatic plants were evaluated in this study. Imazamox doses consisted of 200, 400, and 600 g a.i. ha-1, and spray solution volumes consisted of 25, 50, and 100 L ha-1, with a control (without herbicide application) and ten replications. Applications were performed with a centrifugal energy spray nozzle. The evaluations were carried out considering the percentage of control at 7, 15, 21, and 30 days after application (DAA), and plant dry matter was measured at 30 DAA, as well as leaf retention of spray solutions. An efficacy from 96 to 100% and plant dry matter reduction from 88 to 100% was observed at 30 DAA using imazamox doses of 200, 400, and 600 g a.i. ha-1 and a spray solution volume of 50 L ha-1. Imazamox doses and spray solution volumes were effective in controlling E. crassipes, except for 200 g a.i. ha-1 and 25 L ha-1, respectively. The highest leaf retention of E. crassipes was 0.010 mL cm2 at an imazamox dose of 400 g a.i. ha-1 and volume of 50 L ha-1. The cost of chemical control was 20 times lower when compared to mechanical control, making it economically more viable. These results are important for decision-making on which method and application technology should be used to control E. crassipes.

ABSTRACT: Composition and level of weed infestation interfere with crop yield and increase production costs. This study aimed to identify weed composition and infestation in corn grown with different plant populations, single, and intercropped with palisade grass. The phytosociological method was used to evaluate density, frequency, dominance, and infestation level of weeds in single and intercropped corn, a with conventional (0.90 m) and reduced (0.45 m) spacing, and low and high plant population in Dourados, MS, Brazil. Commelina benghalensis, Echinochloaspp., and Euphorbia heterophylla were the species most found in the treatments. Single corn with higher plant population decreased weed occurrence. Treatments with palisade grass under a reduced spacing showed lower absolute weed infestation (about 75%) when compared to single corn. Weed infestation was lower in the intercropping of corn with palisade grass, with more pronounced effect under a reduced spacing.

ABSTRACT: Knowledge of the level of resistance of weed populations and the herbicides to which they survive is important for recommending suitable advice to farmers and allowing the selection of appropriate management strategies. Whole-plant dose response experiments were carried out to assess the resistance status of eight putative resistant Galium spurium L. populations and one G. aparine L. population, originating from northern Greece. High levels of resistance of both species to the ALS-inhibiting herbicides chlorsulfuron and tribenuron were found, while their susceptible populations were controlled. Three G. spurium (GS) populations showed additional cross-resistance to [florasulam + 2,4-D], whereas the remaining five resistant GS populations were controlled with [tribenuron + mecoprop-p], [florasulam + 2,4-D], and [florasulam + aminopyralid]. Also, [florasulam + fluroxypyr] was very effective against two resistant GS populations tested. DNA sequence alignment of the three GS populations (GS 1, GS 6, and GS 8) with cross-resistance to chlorsulfuron, tribenuron, and florasulam revealed a point mutation at Trp-574 (tryptophan-574), causing amino acid substitution by Leu (leucine). The G. aparine (GA) population showed cross-resistance to chlorsulfuron and tribenuron, but it was controlled with [tribenuron + mecoprop-p], [florasulam + aminopyralid], [florasulam + 2,4-D], and [florasulam + fluroxypyr]. The confirmed cross-resistance of both GS and GA species to chlorsulfuron and tribenuron in northern Greece is the first report of Galium spp. resistance to ALS-inhibiting herbicides in Europe. Finally, all populations (8 GS and 1 GA) that showed resistance to chlorsulfuron and tribenuron were controlled with the mixtures [tribenuron + mecoprop-p] and [florasulam + fluroxypyr].

ABSTRACT: Adjuvants, such as mineral oils, are widely used in the application of herbicides by reducing the drift and evaporation of the droplets and by increasing herbicide uptake by the plant. However, little is known about how mineral oil behaves when in contact with the soil. Thus, the objective of this research was to evaluate the transport of atrazine via leaching with the addition of mineral oil in a soil agricultural under laboratory conditions. To quantify the concentration of the herbicide along the profile of the very clay soil column (30 cm), 14C-atrazine (ring-U-14C) was used with 16,667 Bq of radioactivity per column in volume of 200 mL solution and 0 (control), 1, and 2% mineral oil (v/v) was added in the application volume. Atrazine was applied at the highest commercial dose recommended for sugarcane (4 kg ha-1). After simulation of a precipitation of 200 mm for 48 h, each column was sectioned into six parts of 5 cm and the analytes of each soil sample and the leachate were quantified by liquid scintillation spectrometry. The atrazine remained in the superficial layer of the soil, between 0 and 10 cm of depth, independent of the addition of mineral oil. No atrazine residues were detected in the leachate solution (> 30 cm) in any evaluated treatment. The addition of mineral oil at the time of application of pre-emergence atrazine did not interfere with the transport of this herbicide in the soil profile agricultural via leaching; therefore, the adjuvant may have positive effect only in the herbicide-plant relationship.
Effect of Organic Matter on the Behavior and Control Effectiveness of Herbicides in Soil

ABSTRACT: With extensive use of herbicides in agricultural areas, the risk of contamination of groundwater and surface water by these products has become a worldwide concern. Practices of application or maintenance of soil organic residues that have begun to be used in agriculture for soil nutrition have demonstrated other benefits besides nutrient supplementation, such as reduced mobility and increased soil degradation of herbicides. Because it is the final destination of herbicides, soil and its constituents, especially organic matter in tropical soils, play a prominent role in processes that encompass the dynamics of herbicide molecules. In this context, it is necessary to know the influence of the organic matter and its constituents on the behavior of the herbicides. This review discusses the main relationships of organic matter in the retention, transport, and transformation processes of herbicides in the soil, as well as the interference in the weed control effectiveness of these products. Because of this, knowing the influence of organic matter in the various processes related to the behavior of herbicides in the soil allows us to adopt more appropriate management practices regarding both weed control and remediation of contaminated areas. However, despite the wide range of information on the subject in the literature, each situation is distinct due to the wide variation in the behavioral response of the products to the different types of organic material present in the soil.
