Resumo: | The Asian rust currently is the main disease of soybean culture, having as characteristics the difficult control, by start at the bottom of plants where penetration of the droplets is harder. The fine droplets has been used with the intention of improve the penetration and increase efficiency of agrochemicals, but that are losses by drift easily. New products have been developed to increase deposition of the drops at targets. The aim of this work was evaluate the TA- 35 capacity to improving the deposition of fungicides spray solution with or without mineral oil by aerial and ground applications. Was used a factorial 3x2, three spray solutions composed by Priori Xtra (concentrated suspension of azoxystrobin 200 g L-1 + cyproconazole 80 g L-1 ) mixed with adjuvants, Nimbus (emulsifiable concentrate containing aliphatic hydrocarbons 428 g L-1 ) and TA-35 (soluble concentrate containing sodium lauryl ether sulfate, surfactants, sequestering agents and emulsifiers), in aerial and ground applications. In ground applications was used 50 L ha-1 , TXA 8002 VS spray nozzles and on aerials was used 15 L ha-1 , Turboaero atomizer, both applying fine droplets. Was utilized the Brilliant Blue (FD & C n. 1) tracer to determine the deposits. There were used glass slides as targets to collect spray droplets. After to extract the tracer of the targets using distilled water, the samples were analyzed by spectrophotometry, thereby was possible quantify the tracer deposited on each glass slide. A study to evaluate possible losses of the tracer by degradation or retention also was done. The comparative analysis of treatments was done by statistical method "Confidence Interval for Differences Between the Averages" with 95% of confidence degree (IC95%). There was degradation or retention of the tracer between the processes of application of the droplets and the processing of the samples. The deposition averages with the presence of TA-35 were greatest for both sprayers however, there were not significant differences among the treatments. The viability of TA-35 use may consider other parameters or complementary studies. |

Novas tecnologias como adjuvantes têm sido desenvolvidas para aumentar a deposição das gotas nos alvos, contudo há carência de informações sobre a eficiência da ação esperada para estes produtos. O objetivo deste trabalho foi avaliar a capacidade do adjuvante TA-35 aumentar a deposição de caldas de fungicidas com ou sem óleo mineral em aplicações aéreas e terrestres. O delineamento utilizado foi um fatorial 3x2, três caldas de pulverização com Priori Xtra (suspensão concentrada contendo azoxistrobina 200 g L -1 + ciproconazol 80 g L -1 ) em mistura com os adjuvantes Nimbus (concentrado emulsionável contendo hidrocarbonetos alifáticos, 428 g L-1 ) e TA-35 (concentrado solúvel contendo lauril éter sulfato de sódio, tensoativos, sequestrantes e emulsificantes), além do corante Azul Brilhante (FD&C no 1) como marcador, em aplicações por vias aérea e terrestre. Nas aplicações terrestres utilizou-se o volume de calda de 50 L ha-1 , pontas TXA 8002 VS, e nas aéreas 15 L ha-1 , atomizador Turboaero, ambos aplicando gotas finas. Os alvos utilizados para captação das gotas foram lâminas de vidro. Após a extração do corante dos alvos por lavagem com água destilada, as amostras foram analisadas por espectrofotometria, possibilitando quantificar o deposito de corante em cada lâmina. Um estudo para avaliar possíveis perdas do marcador por degradação ou retenção também foi feito. A análise comparativa dos tratamentos foi feita pelo método estatístico “Intervalo de Confiança para Diferenças entre as médias” com grau de confiança de 95% (IC95%). Houve degradação ou retenção do marcador entre os processos de aplicação das caldas e a leitura das amostras. Apesar do uso do TA-35 ter aumentado as médias de deposição para as aplicações aéreas e terrestres, não houve diferenças significativas entre os tratamentos para cada via de aplicação. Desta forma, outros parâmetros ou estudos complementares devem ser considerados para justificar a viabilidade de uso deste adjuvante.Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Engenharia Rural, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Engenharia Rural, Botucatu, SP, BrasilUniversidade Estadual Paulista (Unesp)Carvalho, Fernando Kassis [UNESP]Antuniassi, Ulisses Rocha [UNESP]Mota, Alisson Augusto Barbiere [UNESP]Chechetto, Rodolfo Glauber [UNESP]Gandolfo, Ulisses Delvaz [UNESP]2016-04-01T18:45:30Z2016-04-01T18:45:30Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article215-221application/pdfhttp://dx.doi.org/10.17224/EnergAgric.2013v28n4p215-221Energia na Agricultura, v. 28, n. 4, p. 215-221, 2013.1808-8759http://hdl.handle.net/11449/13740110.17224/EnergAgric.2013v28n4p215-221ISSN1808-8759-2013-28-04-215-221.pdf9,7548510295485E+015Currículo Lattesreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPporEnergia na Agriculturainfo:eu-repo/semantics/openAccess2024-04-30T14:00:11Zoai:repositorio.unesp.br:11449/137401Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-05-23T11:07:08.021982Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
