Authors: Câmara Alice Barros
Published: October 2019

RESUMO Objetivo O artigo tem como objetivo determinar as famílias de receptores mais estudadas, envolvidas com a doença de Alzheimer, assim como determinar a região do sistema nervoso na qual mais tipos de receptores são expressos e quais funções dos receptores estão predominantemente associadas com a patologia em questão. O artigo busca mostrar os modelos e métodos mais utilizados nessas pesquisas, resumindo alguns achados e discutindo o impacto desses estudos no conhecimento científico. Métodos Esta revisão utilizou-se de uma metodologia sistemática (Prospero; ID 141957). Resultados Pode-se constatar que os receptores de transcrição nuclear foram os mais estudados. A maior parte desses receptores se expressa no córtex cerebral e hipocampo. Adicionalmente, a maioria das pesquisas avaliou os receptores relacionados com os efeitos benéficos na doença. A eliminação da proteína amiloide ou o bloqueio de vias relacionadas à síntese dessa proteína foram as principais funções desempenhadas por esses receptores. Por fim, as técnicas de imunoistoquímica e reação em cadeia de polimerase em tempo real (RT-PCR), respectivamente, foram as mais utilizadas, e os roedores consistiram no principal modelo de estudo. Conclusões Os receptores de transcrição nuclear, o córtex cerebral, o hipocampo, a micróglia e a proteína beta-amiloide mostraram importância na patogênese da doença de Alzheimer neste estudo.

Published: October 2019

Resumo: Objetivou-se avaliar o comportamento do sono de adolescentes de 12 a 17 anos, participantes do ERICA (Estudo de Riscos Cardiovasculares em Adolescentes), estudo de representatividade nacional, segundo características sociodemográficas, turno e tipo de escola, e descrever a correção das horas inconsistentes. A coleta de dados ocorreu em 2013 e 2014. Foram feitas quatro perguntas sobre horas habituais de dormir e de acordar durante a semana e no final de semana, com 24 opções de respostas, uma para cada hora do dia. A análise das inconsistências considerou a distribuição de frequências das respostas quanto às horas habituais de dormir e de acordar, além da compatibilidade com o turno. A duração do sono durante a semana e final de semana foi obtida pela diferença entre horas habituais de dormir e de acordar e foi excluída se ≤ 4 ou ≥ 14 horas. A média de sono total da semana foi calculada pela fórmula: (duração do sono durante a semana x 5 + duração do sono no final de semana x 2)/7. Foram criados três grupos: dados originais (respostas que não necessitaram correções), dados corrigidos (inconsistentes, mas passíveis de correção) e dados excluídos (inconsistentes, para os quais não se tinha critério para correção). A correção recuperou informação inconsistente de 5.988 adolescentes (8%) dos 74.589 participantes. Foram excluídas 7.937 (10,6%) respostas. Os adolescentes cujas informações foram corrigidas ou excluídas são mais novos, do sexo masculino, de escolas públicas e da Região Norte. A correção minimizou perdas e conferiu maior consistência ao tratamento dos dados. O estudo contribui para o aprimoramento da construção de instrumentos de coleta de dados em estudos observacionais, tornando transparente a forma de lidar com as limitações inerentes ao método de coleta de dados.

ABSTRACT Background : Bariatric surgery promotes significant weight loss and improvement of associated comorbidities; however, nutrients deficiencies and weight regain may occur in the middle-late postoperative period. Aim: To investigate nutritional status in 10 years follow-up. Methods : Longitudinal retrospective study in which anthropometric, biochemical indicators and nutritional intake were assessed before and after one, two, three, four, five and ten years of Roux-en Y gastric bypass through analysis of medical records. Results : After ten years there was a reduction of 29.2% of initial weight; however, 87.1% of patients had significant weight regain. Moreover, there was an increase of incidence of iron (9.2% to 18.5%), vitamin B12 (4.2% to 11.1%) and magnesium deficiency (14.1% to 14.8%). Folic acid concentrations increased and the percentage of individuals with glucose (40.4% to 3.7%), triglycerides (38% to 7.4%), HDL cholesterol (31 % to 7.4%) and uric acid (70.5% to 11.1%) abnormalities reduced. Also, there is a reduction of food intake at first year postoperative. After 10 years, there was an increase in energy, protein and lipid intake, also a reduction in folid acid intake. Conclusions : Roux-en Y gastric bypass is an effective procedure to promote weight loss and improve comorbidities associated with obesity. However, comparison between postoperative period of five and 10 years showed a high prevalence of minerals deficiency and a significant weight regain, evidencing the need for nutritional follow-up in the postoperative period.

Resumo As mudanças climáticas são uma ameaça para o setor agrícola. O objetivo do estudo foi avaliar a influência da temperatura e radiação ultravioleta (UV) no desenvolvimento in vitro de isolados de Trichoderma spp. Os experimentos foram conduzidos no Laboratório de Patologia Pós-Colheita, da Embrapa Agroindústria Tropical (Fortaleza - CE). Avaliou-se a influência da temperatura de incubação (30, 35 e 40 °C) no crescimento micelial, bem como na esporulação (conídios.mL-1) e na germinação (%) dos conídios dos isolados de Trichoderma spp. (T. asperellum - SF 04, Quality WG®; T. harzianum - IBLF 006, Ecotrich WP®; e T. harzianum ESALQ - 1306, Trichodermil 1306). Para a avaliação da influência da UV, as placas de Petri contendo os isolados fúngicos foram expostas à luz em diferentes intervalos de tempo (0, 2, 4, 6 e 8 minutos) e obteve-se a germinação relativa. O isolado mais sensível à temperatura foi T. asperellum (SF 04), no qual, a temperatura de 35 °C apresentou menor área de crescimento micelial e menor germinação relativa (38,4%). O isolado T. harzianum (ESALQ 1306) apresentou a menor porcentagem de conídios germinados a 30 °C (63%), porém, teve o maior número a 35 °C (100%). A radiação UV diminuiu a germinação dos conídios e os isolados que apresentaram maior germinação relativa ao final do período de exposição foi T. asperellum (SF 04) e T. harzianum (ESALQ 1306). Estes resultados podem demonstrar uma maior capacidade de adaptação do isolado T. harzianum (ESALQ 1306) às condições extremas de temperatura.

Authors: Gomes Aldenia Ribeiro dos Santos , Alves José Maria Brabo , Silva Emerson Mariano da , Gomes Micaelle Ribeiro dos Santos , Gomes Camila Ribeiro dos Santos
Published: October 2019

Resumo Esse estudo teve por objetivo investigar a inter-relação entre a variabilidade de índices de vegetação (NDVI - índice de Vegetação de Diferença Normalizada, VCI - índice de condição da vegetação) e temperatura (TCI - índice de Condição de Temperatura) sobre o Nordeste do Brasil, utilizando dados de sensoriamento remoto, banco de dados NOAA-NESDIS, obtidos na série histórica de 1982 a 2011. Foram feitas algumas inferências acerca da variação desses índices de vegetação e temperatura, associada as mudanças climáticas, em períodos sazonais e anos de contrastes climáticos sob a influência de El Niños, La Niñas e condições Normais do Pacífico. Os dados de saída das compilações das rotinas Fortran foram disponibilizados em gráficos e gerados pelo software GrADS (Grid Analysis and Display System). Os resultados mostraram forte correlação positiva entre os indices de NDVI associado ao VCI e TCI na região semiárida do NEB. Esse resultado foi devido aos percentuais de precipitação baixos que esta região possui, tornando mais evidente a forte relação destes índices de vegetação e temperatura no semiárido do NEB. Já para outras áreas da região do NEB que possuem maiores índice de precipitação, a relação entre o NDVI e a precipitação não foi tão evidente neste estudo.

Published: October 2019

ABSTRACT: Lavender is an aromatic ornamental plant that is used widely in the perfume, pharmaceutical, cosmetical and food industries. That is why it is important to study ways to promote a production of lavender raw material. For this, four experiments were carried out in order to study the germination and initial in vitro development of lavender. In the first part the efficiency of the use of hydrogen peroxide in the pre-treatment of seeds inoculated in culture media with different concentrations of gibberellic acid was evaluated. Besides that, the influence of the use of Growlux lamps and white fluorescent lamps on plantlets cultivated in MS and LS media at salts concentrations of 50 and 100% was evaluated. Finally, the effect of the gibberellic acid, putrescine, spermine and spermidine in different concentrations was evaluated. Better results were estimated when hydrogen peroxide pretreatment was applied to the seeds with subsequent inoculation in a medium containing 2,5 mg L-1 of gibberellic acid. The use of Growlux lamps did not influence the characteristics observed when compared to the use of white fluorescent lamps, however it was concluded that the species develops more in a LS medium. Concerning the use of polyamines was found that germination, aerial part and number of leaves of the seedlings were generally favored at the concentration of 0,5 mg L-1 except when spermine was applied, which resulted in a lower number of leaves under this condition.

Published: October 2019

ABSTRACT: Purple maize is an important foodstuff for the Peruvian people. Its unique nutritional and antioxidant characteristics makes it widely exported to other countries. However, when contaminated by fungi, it can trigger numerous health problems in the consumers. This study aimed to evaluate the presence of 27 mycotoxins in 63 samples of purple maize collected in Peru. Frequency of occurrence and mean concentration of the following mycotoxins were determined: alternariolmetileter (AME), alternariol (AOH), tentoxin, neosolaniol, nivalenol, wortmannin, deoxynivalenol, 3-acetyl deoxynivalenol, 15-acetyl deoxynivalenol, zearalenone, aflatoxin B1, aflatoxin B2, aflatoxin G1, aflatoxin G2, fumonisin B1, fumonisin B2, fumonisin B3, ochratoxin A, ochratoxin α, T-2 toxin, HT-2 toxin, fusarenon x, cyclopiazonic acid, gliotoxin, agroclavin and citreoviridin. The main mycotoxins reported in purple maize were AME and AOH, with a frequency of occurrence of 14.3 and 7.9%, and mean concentration of 23.3% and 1.8%, respectively. AME and AOH do not have guidance levels in the Brazilian legislation. Contrastingly, levels of mycotoxins which are within the standards of the country’s regulations were below the limit of quantification. The present results suggested that purple maize is a raw material with a great potential for the production and industrialization of special products.

ABSTRACT: The white mulberry leaves are typically available on the market in dried or encapsulated form. It was assumed in the study that appropriate drying of leaves of the white mulberry is significant for obtaining intermediate products with high content of compounds having anti-oxidative activity. The purpose of the study was to determine the influence of the temperature of mulberry leaves air drying on the content of phenolic acids and flavonols. It has been determined that the content of these compounds in the leaves depended on the drying temperature. Drying at 60 °C favored release of phenolic acids and flavonols from complexes and/or formation of new compounds. Their total content was 22% higher than in leaves dried at 30 °C. Drying at 90 °C reduced the phenolic acid and flavonol content by 24%. The most favorable drying temperature was 60 °C.

Abstract Study aimed to evaluate the effect of replacing fish meal with different levels of full fat soybean meal (FFSBM) on growth and digestive enzyme activities in the stomach, Liver and intestine for Clarias gariepinus. Four diets (D1, D2, D3 and D4) were formulated with 0, 15, 20 and 20 g 100-1 protein + DL-methionine by alternating FFSBM with fish meal. The growth of C. gariepinus was found to be significantly decreased when FFSBM replacement increased. Final body weight was 89.69, 79.70, 70.82 and 68.29 g for fish fed on D1, D2, D3 and D4, respectively, with significant differences between treatments. Specific growth rate (SGR) ranged between 3.11 to 2.78%. Proteolytic activity was higher only with alkaline pHs, whereas only very low activity was shown with acidic. Results of liver showed approximately similar results at acid and alkaline. In contrast, higher proteolytic activity in the stomach was observed at acid pHs 3.0 and 4.0 μg tyrosine-1 minute-1 mg-1 protein) whereas lower values were observed at neutral pH 7.0 g tyrosine-1 minute-1 mg-1 protein for catfish fed on the experimental diets. Moreover, trypsin activity was higher for the stomach, followed by the intestine and liver. However, higher amount of amylase observed in the liver than intestine and stomach.

Abstract Due to increased number of herbicide resistant weeds, it is needed to explore the allelopathic potential of plants as an alternative. The research was conducted to investigate allelopathic effects of Carica papaya L. leaf powder and aqueous extract on seeds as well as pre-germinated seeds of Avena fatua L., Helianthus annuus L., Rumex dentatus L., Zea mays L. and Triticum aestivum L. on filter paper and soil in Weed Management Program Laboratory, Department of Plant and Environmental Protection at PARC Institute of Advanced Studies in Agriculture, National Agriculture Research Centre, Islamabad, Pakistan. Germination percentage (%), radicle length (cm) and plumule length (cm) were parameters observed for ‘Plant leaf powder bioassay’ and ‘Aqueous extract method’. Most significant growth inhibition was observed in A. fatua seedlings in filter paper method. A. fatua radicle length was reduced by C. papaya aqueous extract (80%) and leaf powder (89%) bioassays. Plumule length was reduced under the influence of aqueous extract (57-73%) and powdered material (59-77%). The inhibitory effects on other test species were in sequence of H. annuus followed by Z. mays and R. dentatus. The aqueous extract showed non-significant effect on wheat seed germination, radicle and plumule growth. It is suggested that C. papaya aqueous extract can be used as source of weed management in wheat crop.

Published: October 2019

Abstract Fish is the most indispensable source of proteins for individuals and have high nutritional value. On the other hand, the fish culturing raised issues of fish health due to close contact between the aquatic environment and the fish pathogens. So, the aim of the current study was to identify the bacterial pathogens and screen the injured Rainbow trout rearing in different trout hatcheries run under fisheries department of the government of Azad Jammu and Kashmir, Pakistan. Seven bacterial pathogens such as Shigella flexneri, Enterobacter amnigenus, Salmonella Typhimurium, Serratia odorifera, Pseudomonas aeruginosa, Streptococcus pyogenes, and Bacillus cereus were isolated and identified. Results revealed that the injury of fish specimens was due to overcrowding. Instead of rainbow coloration, specimens have darker black in color. The water of ponds was not clean and clear and such conditions was because of the greater quantity of feed thrown in the water. It was concluded that poor hygienic water condition and overloading allowed the opportunistic bacterial contaminations to succeed which cause a serious threat to hatcheries.

Authors: Gül Ü. D.
Published: October 2019

Abstract Synthetic dyes, particularly reactive and acid dyes, are commonly used in the textile industry because of their advantages as excellent color fastness and brightness. Also, surfactants are used for an increment of coloring success in the textile industry. One of the major problems concerning textile wastewater is the treatment of the effluents containing both dyes and surfactants. Biological treatment systems are recommended as useful, economic and eco-friendly methods for treatment of industrial wastewater. The purpose of this study was to investigate the binary removal of a textile dye and a surfactant by growing Aspergillus versicolor culture in molasses medium. The effect of dye and surfactant concentration on the removal of dye and surfactant was determined. This study resulted that 100% of the surfactant and dye molecules removed together with the formation of a dye-surfactant complex by fungus. It is concluded that binary removal systems are very efficient for industrial wastewater treatment.

Published: October 2019

Abstract Among fruits and fruit products, oranges and orange juice are the most widely consumed worldwide. However, the effects of pest infestation of oranges on the quality of orange juice are not yet known. To evaluate the effect of the oriental fruit fly Bactrocera dorsalis on the antioxidant activity of orange juice, we measured changes in the vitamin C (Vc) concentration, total phenol content, and antioxidant activity of orange juice after the introduction of fruit fly eggs. Ten days after the eggs were introduced (larvae removed), the concentration of Vc in orange juice was 18.65 µg/mL, which was 9.16 µg/mL lower than that measured in healthy orange juice. In addition, the total phenol content decreased by 46.519 mg Gallic Acid Equivalents (GAE)/g to 9.748 mg GAE/g. Furthermore, the free-radical scavenging activity decreased from 22.297% to 5.393%. Correlation analysis indicated significant correlations between Vc concentration, total phenol content, and antioxidant activity of orange juice after B. dorsalis infestation. The decrease in Vc concentration, total phenol content and free-radical scavenging activity indicated that B. dorsalis changed the quality of orange juice by affecting the antioxidant activity of the juice after the oranges were infested.

Abstract Many plants may accumulate rainwater, forming phytotelmata, aquatic microhabitats inhabited by various organisms. The aim of this study was to conduct an inventory of heterotrophic flagellates associated with phytotelmata of the bromeliad Aechmea distichantha Lem., found in rocky cliffs on the Upper Paraná River. The bromeliads were removed manually from the rocky wall, the water was removed and cultures of organisms of each plant were mounted in Petri dishes. Sixteen species of heterotrophic flagellate were recorded, drawn and described, among them one species belonging to the Amorpha Domain and 15 species to the Diaphoretiches Domain. The groups with most species were Euglenida and Kinetoplastea. The low diversity of heterotrophic flagellates recorded in this study, compared to the plankton of lakes and reservoirs, is probably related to the fact that phytotelmata are habitats with extreme environmental conditions, thus selecting organisms tolerant to these environments.

Published: October 2019

Abstract: Environmental changes are worrying in a scenario with large knowledge gaps on species diversity and distribution. Many species may become extinct before they are known to science. Considering this scenario, the present study aims to evaluate the known distribution of the species recorded for Maranhão state in Brazilian northeast region and discuss knowledge gaps about Odonata indicating the priority areas for faunistic inventories. Using primary and secondary data together, we present convex minimum polygons of the distribution of all the species registered for the state. In addition, we created maps with the richness of species and number of records of Odonata in the Maranhão state. In primary data sample 269 specimens, represented by 17 genera and 30 species were collected. Of the 30 species collected, 17 are new records for the state of Maranhão; of these, 35.29% are geographically widespread species, occurring in practically all regions of Brazil. Considering the records in the literature, there was a 68% increase in the number of Odonata species known for Maranhão. The most unexplored region is the Cerrado of the state of Maranhão. Furthermore, the transition regions between Cerrado and Amazônia and between Cerrado and Caatinga are also unknown. All these areas are a priority for faunistic inventories.

ABSTRACT Dung beetle species were collected between May 2016 and July 2017 with pitfall traps baited with human feces in four Atlantic Forest sites with different levels of disturbance in the state of Rio Grande do Sul, southern Brazil. We sampled 5,535 individuals belonging to 46 species. Canthidium aff. trinodosum (20.71%), Eurysternus parallelus Castelnau, 1840 (14.82%), Onthophagus catharinensis Paulian, 1936 (12.09%), Scybalocanthon nigriceps (Harold, 1868) (7.61 %), Eurysternus caribaeus (Herbst, 1789) (7.49%), and Canthon rutilans cyanescens Harold, 1868 (7.22%) were the most abundant species, which represented 70% of the individuals sampled. Moreno Fortes Biological Reserve had the higher richness and Morro do Cerrito the higher abundance, while Val Feltrina presented the lowest values. The greatest similarity occurred between Turvo State Park and Moreno Fortes Biological Reserve, while Moreno Fortes Biological Reserve and Val Feltrina had the lowest similarity. Only 11 species (23.9%) occurred in all sites, while 14 species were restricted to only one of the fragments. Both abundance and richness of dung beetles were positively correlated with site temperature but not with precipitation.

Published: October 2019

ABSTRACT: Boll weevil is the major cotton pest in Brazil, and insecticides are widely recommended against it. We determined the susceptibility of boll weevil to insecticides either in single or in mixture ready-to-use formulations, which are registered to spray cotton fields under the hypothesis that mixtures are more toxic to the target pest. Concentration-mortality curves were determined to adult species, simultaneously through dried residues and ingestion. Ten insecticide formulations were studied with five in mixture (lambda-cyhalothrin + thiamethoxam, lambda-cyhalothrin + chlorantraniliprole, thiamethoxam + chlorantraniliprole, and fenitrothion + esfenvalerate) and their five respective single formulations. Cotton leaf discs and cotyledons were dipped into insecticide dilutions prepared by diluting the commercial products into distilled water. Adult mortality was assessed 48 hours after caging adults on treated and untreated materials. The LC50s-concentrations varied from 0.004 to 0.114 g a.i./L, with a relative potency between single and mixture ones, varying from 1.37- to 29.59-fold. Furthermore, lambda-cyhalothrin and thiamethoxam in single formulation were the most toxic insecticides to boll weevil. Among insecticide mixtures, only lambda-cyhalothrin + chlorantraniliprole resulted in a synergic effect; whereas the remaining mixtures showed an antagonistic effect. Therefore, except for the mixture of lambda-cyhalothrin + chlorantraniliprole, the remaining mixtures did not enhance toxicity against the boll weevil and should be recommended only when aimed at different purposes.

Abstract Introduction: Physiological responses to the 6-min walk test (6MWT) have been increasingly evaluated in patients with cardiopulmonary diseases. However, previous studies did not include healthy persons. Objective: To evaluate the intensity of 6MWT, to develop a series of predictive equations for the physiological variables and to test their reliability in healthy middle-aged and older adults. Method: We evaluated 102 non-trained healthy adults (54 women, aged 61 ± 10 years) and a cross-validation sample of 30 participants. We measured physiological responses to the 6MWT and a cardiopulmonary exercise testing (CPET) on a treadmill. Results: The R2 values for regression analysis adjusted by age, body mass, stature, and sex ranged from 0.25 for heart rate and 0.46 for peak V ˙ O 2 The 6MWT distance and 6MWT peak V ˙ O 2 represented 110 ± 10% and 102 ± 15% of the predicted values, respectively, using our equations. The intensity of 6MWT corresponded to 72 ± 13% of the peak O2 and 78 ± 23% of the peak HR in the CPET. Peak V ˙ O 2 in the CPET was adequately predicted by 6MWT peak V ˙ O 2 (R2 = 0.76) and 6MWD (R2 = 0.54). Conclusion: The 6MWT represents a moderate to high-intensity test in middle-aged and older healthy adults and is valid for assessing maximal aerobic exercise capacity. Physiological responses to the 6MWT may be adequately predicted with a combination of anthropometrics and demographics.

Cultura e formação: a ideia de formação humana na sociedade contemporânea
Authors: Goergen Pedro L.
Published: October 2019

Resumo Neste texto o leitor encontra uma reflexão crítica sobre a formação humana nocontexto da proeminência das relações econômicas na orientação da vida subjetivae social. Argumenta-se que o sistema econômico vem se tornando o sentido e onorte do processo educacional. Nestes termos, não mais a formação do ser humanoem suas dimensões racional, ética e estética representa o sentido e o fio condutordo processo formativo, mas a preparação e a transformação das pessoas em “capitalhumano”, adaptado aos interesses do mercado. A pergunta a ser respondida é se, navalorização extrema do econômico, o ser humano ainda tem condições e chancesde preservar sua liberdade e autonomia como condições essenciais de suahumanidade. Defende-se que a educação pode e deve retomar uma agenda proativa,visando a educação integral do ser humano.

Resumo Com base na teoria discursiva do letramento e na análise de discurso de matrizfrancesa (pecheutiana), discutimos como circula a oralidade no contexto escolar;problematizamos a negação dessa modalidade discursiva em livros didáticos,programas oficiais de ensino e atividades pedagógicas, bem como nos dizeres deprofessores do ensino fundamental. Destacamos o não reconhecimento da autoriaem textos orais e, ainda, a violência simbólica presente na recusa em aceitar aoralidade como uma modalidade legítima de língua, de instalação de autoria e desubjetividade. Defendemos um trabalho pedagógico que se valha de fatos, pessoase rotinas conhecidos dos alunos, a fim de que possam transferir esse conhecimentopara a escrita, o que pode funcionar como um disparador capaz de superar adistância entre as formas escritas e orais da língua.

ABSTRACT Controlling volunteer plants was aggravated due to the emergence of genetically modified glyphosate-resistant cultivars, requiring new technical recommendations. This work was developed with the objective of evaluating alternatives for chemical control of glyphosate-resistant maize infesting soybean crops, using ACCase inhibiting herbicides. Two experiments were carried out, one in Santa Cruz das Palmeiras (SP) and other in Não-Me-Toque (RS), Brazil. Volunteer maize plants were simulated with seeds of the DKB 390 YGRR2 hybrids, distributed between rows of soybean crops, at the density of 6 plants m-2. Combinations of the herbicides clethodim (65 and 84 g ha-1), sethoxydim (138 and 165 g ha-1), and haloxyfop (36 and 45 g ha-1) were applied at two phenological stages of the soybean crop [three (3T) and six (6T) trifoliate leaves], corresponding to the V4/V5 and V7/V8 stages of the volunteer maize, respectively, resulting in 14 treatments. A treatment without herbicide application and a treatment with manual weeding were included as check plots. Applying graminicides on maize plants at V4/V5 stage resulted in more consistent results and general efficacy. Soybean yield was lower when applying herbicide only on maize plants at V7/V8, in both locations. Therefore, management practices for glyphosate-resistant volunteer maize should be adopted early, on maize plants at the V4/V5 stage, mainly when the maize plants are from lost grains in the harvesting process. The use of the herbicides clethodim and haloxyfop results in consistent control efficacy of volunteer maize plants.

ABSTRACT Ecuador has a vast number of native species with fungicidal, herbicidal, and insecticidal properties, of which several have been studied; however, few plant species have been applied for the development of commercial products. Ocotea quixos is an indigenous plant of the Ecuadorian Amazon that has fungicidal properties. In this work, we focus on developing an emulsifiable concentrate that is physically stable for use in the agricultural industry. The study aimed to determine the appropriate formulation to prepare an emulsifiable concentrate with thermodynamic stability. For the formulation, we used Ocotea quixos essential oil with cinnamaldehyde as an active ingredient, with solvesso 100 as the solvent, two non-ionic emulsifiers (Span-20 and Tween-20), and calcium phenyl sulfonate as an anionic emulsifier to obtain a stable product. The results showed that the OC5C emulsifiable concentrate has the best stability characteristics with the hydrophilic-lipophilic balance (HLB) within the range of 14 to 16 at room temperature as well as at high and low temperature with a drop size between 3 and 4 µm.

ABSTRACT Citrus black spot (CBS) is a disease caused by the Phyllosticta citricarpa fungus that causes lesions in fruits and, in more severe stages, fruit drops. The use of systemic fungicides is the main control measure for CBS; however, an alternative control measure is the use of cupric fungicides applied alone with short intervals. Therefore, the objective of the present work was to evaluate the effect of applications of copper oxychloride at different rates on the control of CBS. The experiment was conducted in Bebedouro, SP, Brazil, in the 2014/2015 crop season, in a randomized block design, using a Citrus sinensis variety (Valencia). The treatments consisted of copper rates (zero - control; 31, 24.5, 18.5, 12.2, and 9.1 mg of metal copper per cubic meter of canopy) using copper oxychloride (concentrated suspension - CS; 588 g L-1 of copper oxychloride or 350 g L-1 of metal copper), and an additional treatment with application of a cupric fungicide (cuprous oxide) and a strobilurin fungicide. The applications were carried out with 14-day intervals, starting when 2/3 of the petals of the plant's flowers were fallen, totaling 14 applications. The incidence and severity of CBS were evaluated five times with 30-day intervals up to mid-November, when the fruits were harvested. The data were used to calculate the area under the disease progress curve (AUDPC). Applications of copper oxychloride CS at rates of 31 and 24.5 mg m-3 with 14-day intervals are efficient for the control of CBS, with similar efficiency to the farm standard treatment.

ABSTRACT Ramularia leaf spot (RLS) is the major cotton disease in Brazil and one of the main causes of crop yield reduction. The disease causes defoliation reduces photosynthetic capacity and causes premature opening of bolls. Due to the impact of RLS on the production of Brazilian cotton and the lack of scientific publications investigating the disease, the present work aims to evaluate the efficiency of fungicides in controlling disease and their impact on yield and fiber quality. Three field experiments were carried out during the 2014/2015 and 2016/2017 seasons in Planaltina, Federal District and Cristalina, Goiás. Experiments followed a randomized complete block design (4 blocks) and treatments consisted of the application of fungicides, plus a non-treated plot. The fungicide applications began preventively and were repeated every 14 days until six sprays had been completed. Severity of RLS was assessed and used to calculate the area under disease progress curve (AUDPC). Yield and cotton fiber quality were also evaluated. All fungicides had reduced AUDPC and obtained higher cotton yields in relation to the non-treated plot. Strobilurin-group fungicides (azoxystrobin, pyraclostrobin and picoxystrobin) showed low effectiveness when sprayed alone. The demethylation inhibitor fungicides (difenoconazole, epoxiconazol, tetraconazol and metconazole) were more effective than the strobilurins. The highest efficiency rates were achieved by application of pyraclostrobin + fluxapyroxad, pyraclostrobin + epoxiconazole + fluxapyroxad and fentin hydroxide. Disease severity affected cotton yield, causing losses from 14.8% to 31.7%. Resultant reductions in cotton fiber quality negatively affect the micronaire composition, altering the length, strength and uniformity of fibers.

ABSTRACT Soil is the habitat for a number of living organisms that perform essential functions within the ecosystem; their functions and interactions are modified according to different ways of land occupation. Thus, the objective of this study was to evaluate the diversity of edaphic fauna in different soil occupation systems. The study was carried out in different soil occupation systems: millet, maize, soybean, eucalyptus, preserved cerrado, disturbed cerrado, and pasture, with 130 pitfall traps installed per treatment. Soil fauna organisms were identified at the level of large groups (orders and family), and then examined under the following biological diversity indices: Shannon index, Pielou index, average and total richness, and abundance. The highest abundance was found under millet growing conditions (9,974 individuals), and the lowest abundance values were found in soybean soil (222 individuals) and maize (824 individuals). Uniform distribution of groups in the area with soybean crops, due to the homogeneous management of the area, provided the highest biological index (H'=2.69). Principal component analysis (PCA) explained 50.9% of the data along the main axis and 34.6% of the data along the secondary axis. The different systems of soil occupation showed different abundance and diversity, demonstrating how soil occupation interferes with the dynamics of the invertebrate soil fauna.

Abstract Cabbage cultivars currently cultivated present high yield potential and may present differences regarding absorption and use of nutrients. Thus, studies quantifying plant growth and nutrient accumulation are the basis to improve fertilization efficiency and optimize yield. This study aimed to determine the dry matter and nutrient (N, P, K, Ca, Mg, S, Cu, Fe, Mn, and Zn) accumulation curve of cabbage cultivars during two growing seasons. Cultivars Astrus Plus and Green Valley were cultivated during summer-autumn crop season, while Astrus Plus and Fênix during the autumn-winter crop season. Plants were sampled after transplanting at 10-day intervals until harvest. Dry matter and nutrient accumulations are variable with growing season and cultivar. The highest dry matter and nutrient accumulation rates occur in the last ten days of the cycle. Fertilizations with N, P, K, Fe, and Zn should receive more attention due to higher harvest indices.
