Title: Yield Loss Caused by Meloidogyne graminicola on Lowland Rainfed Rice in Bangladesh.
Abstract: The impact of Meloidogyne graminicola on growth and yield of lowland rainfed rice was assessed with and without carbofuran in a rice-wheat rotation area of northwestern Bangladesh. The experiment was conducted on farmer fields and at a research station, with experimental plots arranged in a randomized complete block design. Prior to transplanting, rice seedling height and dry weight were greater (P </= 0.05) and soil levels of M. graminicola were lower (P </= 0.05) in the treated seedbed plots compared to the nontreated control plots. Nematicide application to the field at transplanting had a greater effect (P </= 0.05) on mid-season plant growth than did nematicide application to the seedbed at sowing, and rice yield increased by 1.0 t/ha where carbofuran was applied to the seedbed and field-both at the research station (P </= 0.05) and on farmer fields (P </= 0.10)- compared to a nontreated control. This is the first report of a negative impact of M. graminicola on growth and yield of lowland rainfed rice in production fields in Bangladesh.
