Resumo: The main objective of this work was to present an algorithm of the computational program based on a numeric method to estimate losses of herbicides caused by aerial spraying. This method has as input, the frequency of droplets sizes collected on water sensitive paper, observed on the Porton graticule coupled to the microscope. With this values the accumulated distribution of the mean diameter is computed for droplets size and for droplets volume, both formed by the spraying nozzle, following already known methodology. Data obtained for this two distribution curves make possible to use a numeric method of the linear interpolation in order to obtain the volume median diameter and the numeric median diameter. These two values are fundamental to the determination of the droplets uniformity. This method was implemented on computer language to enable users to compare observed values against estimated by interpolation techniques. An example of the program is presented for an hydro sensitive paper capture on the sampling carried out in Pelotas, RS, Brazil.

Este método apresenta como entrada de dados a freqüência de tamanhos das gotas em papéis hidrossensíveis, observadas no gratículo de Porton acoplado ao microscópio. A partir desses valores calcula-se a distribuição acumulada do diâmetro médio do tamanho e do volume das gotas formadas pelo bico de pulverização utilizados na aplicação, conforme metodologia já conhecida. Os dados obtidos para estas curvas de distribuição permitem fazer uso do método numérico de interpolação linear para a obtenção do diâmetro mediano volumétrico e do diâmetro mediano numérico da gota. Estes valores são fundamentais para a determinação da uniformidade de gota. Este método numérico foi implementado em linguagem computacional, permitindo a comparação de valores observados com os encontrados pela interpolação, para papéis espalhados nas faixas de aplicação. É apresentado um exemplo de utilização do programa para placas de papel hidrossensível amostradas em experimento realizado em Pelotas, RS.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPessoa, Maria Conceição Peres YoungChaim, Aldemir1999-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5143Pesquisa Agropecuaria Brasileira; v.34, n.1, jan. 1999; 45-56Pesquisa Agropecuária Brasileira; v.34, n.1, jan. 1999; 45-561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5143/2335info:eu-repo/semantics/openAccess2010-07-15T13:51:03Zoai:ojs.seer.sct.embrapa.br:article/5143Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-15T13:51:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
