Methods for use of insecticides in control of the rice water weevil Oryzophagus oryzae (COLEOPTERA CURCULIONEDAE)

Methods for use of insecticides in control of the rice water weevil Oryzophagus oryzae (COLEOPTERA CURCULIONEDAE)

Two field experiments with rice were conducted at Rio Grande do Sul, Brazil, with the principal finality of studying the efficiency of two methods in control of the rice water weevil, in relation to the injuries these larvas cause in the roots or "root maggots". The results obtained demonstrated that both the treatment of seeds with insecticides in powder that has effect by contact and digest (preventive method), and the application of granulated and solvable systemic insecticides (control method) protected the roots and proportionated an increase in the yield of rice. It was observed a great and more uniform germination, when the treatment of the seeds with insecticides and fungicides was realized.

Foi estudada, em dois experimentos de campo com a cultura do arroz, a eficiência de métodos de controle à Bicheira-do-arroz, Oryzophagus oryzae (Costa Lima 1936), cujas larvas danificam o sistema radicular das plantas.Os resultados obtidos demonstraram que tanto o tratamento de sementes com produtos químicos em pó, que atuam por contato e ingestão (método preventivo), como as aplicações de inseticidas sistêmicos, na formulação granulada e por pulverizações (método de combate), protegeram as raízes e proporcionaram aumentos na produção de grãos.Foi obtida maior e mais uniforme germinação através do tratamento de sementes com produtos químicos.
