Outline of Final Research Achievements

Myanmar is the 7th largest rice producing country in the world, but its yield per unit area is not high. We focused on the possible contribution of nematode damage to rice yield. Rice rot nematodes Hirschmanniella oryzae and root-knot nemaotdes Meloidogyne graminicola　were detected in 80% and 60% of rice fields, respectively, surveyed in this study. Nematicide application increased the rice yield by 30% in average. This study revealed a significant yield loss in rice production by plant-parasitic nematodes.
