Resumo: Oryzophagus oryzae, the rice water weevil (RWW), an important insect pest in irrigated rice crop in Brazil, can reduce 10 to 30% the grain yield. The purpose of this study was to compare the efficiency of RWW chemical control by seed treatment, foliar spray or rice irrigation water treatment, using the more appropriated active ingredients, formulations and rates, to each insecticide application method. The seed treatment with carbossulfan TS (300 g/100 kg) or fipronil FS (50 and 75 g/100 kg), and foliar spray with fipronil WDG (60 and 80 g/ha), or lambdacyalothrin (10 glha)provided high larval control (92 to 99%) and avoided grain yield reduction (18 to 25%), equivalent to standard control method, based on carbofuran G (750 g/ha) applied directly on rice irrigation water. Fipronil G (60 and 80 g/ha) was significantly less efficient than granulated carbofuran. It was concluded that seed treatment and foliar spray, according to active ingredients used, are more efficient for RWW control than granular carbofuran applied directly on irrigation water.

Utilizaram-se ingredientes ativos, formulações e doses apropriadas a cada método de aplicação. O tratamento de sementes com carbosulfan TS (300 g/100 kg) ou fipronil FS (50 e 75 g/100 kg) e a pulverização foliar com fipronil WDG (60 e 80g/ha) ou lambdacialotrina CE (10 g/ha), proporcionaram alta redução da população larval (92 a 99%) e evitaram perdas na produção de grãos (18 a 25%), em níveis significativamente iguais aos obtidos com o método de aplicação padrão, que consiste em distribuição de carbofuran G (750 g/ha) diretamente na água de irrigação. Fipronil G (60 e 80 g/ha), aplicado à água de irrigação, reduziu a população larval em nível (76 e 81%) significativamente inferior ao de carbofuran G. Concluiu-se que o tratamento de sementes e a pulverização foliar, dependendo do ingrediente ativo usado, são tão eficientes no controle de O. oryzae, quanto à aplicação de carbofuran granulado, diretamente na água de irrigação.Departamento de Diagnóstico e Pesquisa Agropecuária.
