Root-knot nematode Meloidogyne incognita (Kofoid & White) Chitwood is an economically important pathogen of many agricultural crops, and the frequency of occurrence, abundance and importance of this nematode in resource-poor agricultural production systems make control neces- sary. Field studies were conducted in 2004 and 2005 to determine yield loss of Roselle due to natural infestation by M. incognita using Carbofuran 3G at 2 kg a.i./ha and untreated as check. The yield of Roselle was found to be higher with the application of nematicide-Carbofuran 3G at 2 kg a.i./ha. The percentage increase over control was 48.7 and 40.8% in the years 2004 and 2005, respectively. A sig- nificant reduction in the yield of Roselle in untreated plots was mainly attributed to direct damage of the root system by the feeding of root-knot nematode M. incognita. Root-knot nematode population in carbofuran treated plots was significantly lower than in untreated check in the two years, also at harvest. In the check the nematodes multiplied many folds during the cropping season. High nema- tode population in the untreated check decreased plant growth and ultimately reduced the number of seeds and weight of seeds.
