Resumo: | Spray nozzles were evaluated at two different spraying times (14h and 17h 30m), in Mato Grosso do Sul, Brazil regarding Asian soybean rust control (Phakopsora pachyrhizi Sidow). Four spray nozzles were evaluated: deflector plain tips, double deflector plain tips, extended range flat spray tips and double plain tips. A commercial formulation of epoxiconazole and pyraclostrobin (0,5 L ha-1) was sprayed in the plots. Soybean leaves were collected at the top, middle and lower canopy, for assessment of the number of lesions and uredinias. In addition, leaf area affected by P. pachyrhizi was estimated. Plots sprayed with double deflector plain tips had lower uredinia counts in the lower canopy compared to the other tips tested. Sprays done early in the afternoon with double deflector plain nozzles had lower uredinia counts compared to the other treatments. Smaller defoliation and greater a-thousand grain mass were detected in plots sprayed with fungicide using a double deflector plain tip compared to the deflector plain nozzle. Soybean yield was not affected by nozzles and time of fungicide spray. |

Avaliaram-se quatro pontas de pulverização: jato plano defletor, jato plano defletor duplo, já to plano de faixa ampliada, jato plano duplo. As aplicações ocorreram nos horários de 14h e 17h 30min com pulverizador costal à pressão constante. O fungicida utilizado foi uma formulação comercial de epoxiconazol e piraclostrobina (0,5 L ha-1). Foram coletados folíolos nos terços superior, médio e inferior para avaliação do número de lesões, urédias, e área foliar lesionada. Menor número de urédias no terço inferior foi observado em plantas que receberam aplicação de fungicida às 14h via ponta jato plano defletor duplo em relação às demais pontas. A aplicação de fungicida, independente do tipo de ponta, não resultou em alterações nos níveis de controle da ferrugem asiática nos terços superior e médio. Menor desfolha e maior massa de mil grãos foram detectadas quando a aplicação foi realizada com a ponta jato plano defletor duplo em relação à jato plano defletor. A produtividade não foi afetada pelo uso de diferentes pontas e horários de aplicação do fungicida.UEL2013-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa cientificaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1101110.5433/1679-0359.2013v34n5p2037Semina: Ciências Agrárias; Vol. 34 No. 5 (2013); 2037-2048Semina: Ciências Agrárias; v. 34 n. 5 (2013); 2037-20481679-03591676-546Xreponame:Semina.
