Resumo: This study aimed to evaluate the effect of the aerial and ground application of fungicide in the control of corn diseases and in the spray deposition on the canopy. The hybrid AG7010 was sown and the spray deposition on the bottom, middle and upper canopy of the crop, disease severity and yield were evaluated after the application of the fungicide (pyraclostrobin + epoxiconazol), at the V8-V10 stage. The aerial application was accomplished with spray volumes of 15 and 30 L ha-1, using flat-fan spray nozzles, and the ground one with 100 L ha-1, using turbo twin flat-fan and air induction turbo flat-fan spray nozzles. An additional treatment that received no fungicide was also evaluated. The study of the deposition was achieved using water sensitive papers. It was concluded that that the conventional treatments presented larger droplet density in the corn canopy; however all of the treatments provided the minimum deposition recommended for fungicide application. The aerial application using spray volume of 30 L ha-1 provided similar yield to the conventional treatments, showing to be technically feasible to use.

Realizou-se a semeadura do híbrido AG7010, avaliando-se após a aplicação do fungicida (piraclostrobina + epoxiconazol), no estádio fenológico V8 a V10, a deposição de calda na parte inferior, média e superior do dossel da cultura, a severidade de doenças e a produtividade. A aplicação aérea foi realizada com volumes de calda de 15 e 30 L ha-1, empregando pontas de jato plano, e a aplicação terrestre com 100 L ha-1, empregando pontas de jato plano defletor com indução de ar e pontas de jato plano defletor duplo. Como testemunha foi utilizado um tratamento sem o recebimento de fungicida. O estudo da deposição foi realizado com o emprego de papéis hidrossensíveis. Concluiu-se que os tratamentos terrestres apresentaram maior densidade de gotas no dossel da cultura do milho, mas todos os tratamentos proporcionaram a deposição mínima recomendada para aplicação de fungicida. A aplicação aérea empregando volume de calda de 30 L ha-1 proporcionou produtividade semelhante aos tratamentos terrestres, mostrando ser viável tecnicamente sua utilização.Revista Ciência Agronômica2010-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://periodicos.ufc.br/revistacienciaagronomica/article/view/84026Revista Ciência Agronômica; v. 41 n. 3 (2010)1806-66900045-6888reponame:Revista ciência agronômica (Online)instname:Universidade Federal do Ceará (UFC)instacron:UFCenghttp://periodicos.ufc.br/revistacienciaagronomica/article/view/84026/228178Cunha, JoãoSilva, LeandroBoller, WalterRodrigues, Jaquelineinfo:eu-repo/semantics/openAccess2023-02-28T07:24:01Zoai:periodicos.ufc:article/84026Revistahttps://periodicos.ufc.br/revistacienciaagronomicaPUBhttps://periodicos.ufc.br/revistacienciaagronomica/oai||alekdutra@ufc.br|| ccarev@ufc.br1806-66900045-6888opendoar:2023-02-28T07:24:01Revista ciência agronômica (Online) - Universidade Federal do Ceará (UFC)false
