Abstract

Com o objetivo de se avaliar a eficiência de inseticidas granulados no controle da Orthezia praelonga em laranjeiras, foram empregados o aldicarbe 15% e o imidaclopride 5%, aplicados ao solo. Os tratamentos foram seis, com quatro repetições: A) testemunha; B) aldicarbe, 100g/pl; C) aldicarbe, 65g/pl; D) imidaclopride, 100g/pl; E) aldicarbe, 130g/pl; F) imidaclopride, 75g/pl. Foram feitas seis avaliações: uma prévia e outras cinco após 07, 20, 34, 49 e 70 dias da aplicação. Os melhores tratamentos foram: aldicarbe 100g/pl e aldicarbe, 130g/pl, aos 49 e 70 dias, respectivamente.The experiment was carried out on adult orange-trees in the county of Limeira, SP, Brazil. The objective was to evaluate the efficiency of insecticide granules with 15% aldicarb and 5% imidadoprid, applied to the soil, to control the citrus coccid Orthezia praelonga Douglas, 1891. Treatments were six: A) check; B) aldicarb, 100g/pl; C) aldicarb, 65g/pl; D) imidacloprid 100g/pl; E) aldicarb, 130g/pl; F) imidacloprid, 75g/pl of commercial insecticide granules. Six evaluations were made, one previous and other five 07, 20, 34, 49 and 70 days after application. The most efficient treatments were E and B at 49 and 70 days, respectively.
