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 necessary. 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 significant 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 nematode population in the untreated check decreased plant growth and ultimately reduced the number of seeds and weight of seeds.

Mątwik Meloidogyne incognita (Kofoid & White) Chitwood jest ekonomicznie ważnym patogenem wielu roślin rolniczych, a liczne występowanie i duże znaczenie w warunkach zaniedbań agrotechnicznych sprawia, że jego zwalczanie jest konieczne. W celu określenia strat plonu ketmii Hibiskus sabdariffa L. (Roselle) wywoływanych przez tego szkodnika w latach 2004 i 2005 przeprowadzono badania na naturalnie zakażonych polach w Nigerii. Do zwalczania patogena stosowano Carbofuran 3 g w dawce 2 kg składnika aktywnego na hektar. Wzrost plonu H. sabdariffa w wyniku przeprowadzonego zabiegu wynosił w latach 2004 i 2005 odpowiednio 48,7 i 40,8%. Istotną redukcję plonu na nietraktowanych poletkach kontrolnych przypisywano głównie bezpośrednim uszkodzeniom systemu korzeniowego przez M. incognita. Populacja M. incognita na traktowanych Carbofuranem poletkach doświadczalnych była w obydwóch latach badań istotnie niższa niż w nietraktowaniej kombinacji kontrolnej, również w okresie zbioru. Na poletkach kontrolnych mątwik rozmnażał się wielokrotnie w czasie wegetacji, a liczna jego populacja była przyczyną ograniczenia wzrostu roślin, ilości nasion i ich masy.
