Resumo: | The presence of dew at fungicide spray might change de efficiency. So, the work was carried out to evaluate changes on fungicides efficiency on control of wheat diseases due to presence of dew on leaf surface at the moment of spray. In addition, the time of spray and gallonage of the product was considered. Two experiments were carried out at Itaara RS. The first experiment was structured based on three factorial design which factors were fungicides, nozzles (hollow cone, flat fan and twin jet) and dew (presence or absence). It was used the gallonage of 200 L/ha. The second experiment considered the time of spray and fungicide gallonage (60, 80 and 100 L/ha). The fungicide spray was not influenced by the presence of dew on leaf surface at the moment of application since the nozzles produce very small droplets with no wash out. Application of fungicides with no dew on the leaf surface produced good disease control. However, the nozzle utilized should produce small droplets. Fungicide application with a gallonage of 100 L/ha showed efficiency if temperature, humidity and wind velocity were adequate to the spray. |

Assim, o presente trabalho teve como objetivo avaliar a eficiência da aplicação de fungicidas na presença e/ou ausência de orvalho no controle de doenças foliares na cultura do trigo bem como avaliar a influência do horário de aplicação e do volume de calda utilizado sobre a eficácia de fungicidas no controle de manchas foliares na cultura do trigo. Foram instalados dois experimentos em Itaara RS. O primeiro foi estruturado com base na interação de três fungicidas, três tipos de pontas de pulverização (cone, leque, duplo leque), presença ou ausência de orvalho na planta submetida aos fungicidas. Para aplicação dos fungicidas foi utilizado vazão de 200 L/ha. No segundo experimento foram avaliados diversos fatores da aplicação como horários e volumes de calda (60, 80 e 100 L/ha). Os resultados obtidos mostraram que as aplicações dos fungicidas não foram influenciadas pela presença de orvalho, quando utilizadas pontas que produziram gotas do tipo muito fina e que não causaram escorrimento dos fungicidas. Aplicações de fungicidas na ausência de orvalho apresentaram bom controle quando as pontas utilizadas produziram gotas classificadas como finas. Aplicações de fungicidas com a utilização de 100 L/ha se tornaram eficientes quando aplicadas sob condições adequadas de temperatura, umidade e velocidade do vento.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaTecnologia de aplicaçãoOrvalhoControle químicoTrigoSpray tecnologyDewChemical controlWheatCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLATecnologia de aplicação de fungicidas na cultura do trigoFungicide spray tecnology on wheat cropinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisBalardin, Ricardo Silveirohttp://lattes.cnpq.br/6547445501940321Schlosser, José Fernandohttp://lattes.cnpq.br/0575023987760421Costa, Ivan Francisco Dressler dahttp://lattes.cnpq.br/6426393869748708http://lattes.cnpq.br/3958761789174922Meneghetti, Rosana Ceolin500300000008400500500500500db30a6fa-b8fd-467f-8b97-06372e6314300c1076d9-3133-4c2b-a5b3-680c4e649feb5721c5d7-b64f-4ec5-b450-c6ba78ccf039f35a8b78-d4fe-4475-916d-7cf6e9fe2263info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALROSANAMENEGHETTI.pdfapplication/pdf399234http://repositorio.ufsm.br/bitstream/1/7505/1/ROSANAMENEGHETTI.pdf44c13b4a7c80041413bca5d39f7c1642MD51TEXTROSANAMENEGHETTI.pdf.txtROSANAMENEGHETTI.pdf.txtExtracted texttext/plain79971http://repositorio.ufsm.br/bitstream/1/7505/2/ROSANAMENEGHETTI.pdf.txt0865ab30ea8c0db644f09a51633b046eMD52THUMBNAILROSANAMENEGHETTI.pdf.jpgROSANAMENEGHETTI.pdf.jpgIM Thumbnailimage/jpeg4915http://repositorio.ufsm.br/bitstream/1/7505/3/ROSANAMENEGHETTI.pdf.jpg0505bc368ee1923dd93a407edce1fc6bMD531/75052022-08-12 17:06:15.357oai:repositorio.ufsm.br:1/7505Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-08-12T20:06:15Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
