Summary: Brazilian cotton production is located in regions in which pluvial precipitation indexes are around 2,000 mm per year. Growth regulator application in conditions under such indices can make product to be washed before being absorbed by the plants. The objective of this research was to evaluate the effect of mepiquat chloride wash by simulated rain occurring at different times after the product application on cotton plants. The experiment was accomplished in greenhouse conditions, in pots of 12 L with three cotton plants cv. DeltaOpal. Mepiquat Chloride was sprayed at pin-head square, at 12.5 g ha-1 a.i. Treatments consisted on two simulated rainfalls intensity (10 and 20 mm) at 0, 2, 4, 8, 16 and 32 hours after the product application and a treatment without rain, with four replications. A 10 mm rain was enough to wash the product from cotton leaves irrespectively of the time after application of the regulator. If there is rain 0, 2, 4, 8, 16 or 32 hours after product application, it should be reapplied 131, 125, 120, 110, 93 and 70 mL ha-1, respectively

A aplicação de reguladores de crescimento em condições com esse índice faz com que o produto aplicado seja lavado antes de ser absorvido pelas plantas. O objetivo deste trabalho foi avaliar o efeito da lavagem do cloreto de mepiquat aplicado no algodoeiro, por chuvas simuladas em diferentes períodos após a aplicação do produto. O trabalho foi realizado em casa de vegetação, utilizando vasos de 12 L, com três plantas da cultivar DeltaOpal. No aparecimento do primeiro botão floral, aplicou-se cloreto de mepiquat na dose de 12,5 g ha-1 de i.a. Os tratamentos consistiram de duas lâminas de chuva, 10 e 20 mm, a 0, 2, 4, 8, 16 e 32 horas após aplicação do produto e sem chuva, com quatro repetições. Uma chuva de 10 mm foi suficiente para lavar o produto das folhas independentemente do tempo de ocorrência após a aplicação do regulador. Se houver ocorrência de chuva 0, 2, 4, 8, 16 e 32 horas após a aplicação do produto, a reposição deve ser de 131, 125, 120, 110, 93 e 70 mL ha-1, respectivamente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMateus, Gustavo PavanLima, Eduardo do ValleRosolem, Ciro Antonio2004-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6819Pesquisa Agropecuaria Brasileira; v.39, n.7, jul. 2004; 631-636Pesquisa Agropecuária Brasileira; v.39, n.7, jul. 2004; 631-6361678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6819/3875info:eu-repo/semantics/openAccess2014-07-23T18:44:13Zoai:ojs.seer.sct.embrapa.br:article/6819Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-23T18:44:13Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
