Abstract :

---

An experiment was carried out in order to study the methods of managing striped rice stem borer, Chilo suppressalis Walker on rice, with 11 treatments including the early planted, late planted, Trichogramma brassicae Bezdenko release, 10 Diazinon GR, Bt microbial insecticide, sex pheromone, T. brassicaeþBt, T. brassicaeþsex pheromone, sex pheromoneþBt, T. brassicaeþsex pheromoneþBt and control. In this study, the studied traits included the percentage of brownish leaf sheath (BS), dead heart (DH), white head (WH), yield per hectare and the percentage of converting paddy rice to white rice. The results showed that the best yield in all traits was related to the integrated treatment of T. brassicaeþsex pheromoneþBt, which was in the highest group and its amount in BS was 1.99, in DH was 1.37, in WH was 0.34, the yield/ha was 5910 kg and the percentage of converting paddy rice to white rice was 63.
