Resumo: Leaf miner is a major coffee tree pest and it causes severe losses. Most farmers perform chemical control in an attempt to reduce injuries caused to the crop. Thus, the current study aims to analyze spraying efficiency and control effectiveness according to the management plan adopted in a coffee farm in Minas Gerais Cerrado region. The application was performed using Arbus sprayer, model 2000, at the pressure of 600 kPa. The droplet spectrum was analyzed using water-sensitive paper. The plant architecture influence on the application quality was evaluated through the droplet spectrum and control efficacy. It was concluded that the plant architecture affected application efficiency in relation to the crown height and depth, and spraying was effective in the phytosanitary control of coffee leaf miner, reaching 87.5% control efficiency ratios, considering that the infestation was three times higher at the application time than that recommended for the applied pesticide.
