In a nematode survey of eight commonly grown root and tuber crops (cassava, sweet potato, potato, yam, tannia, taro, carrot and turmeric) from 430 fields in Uganda, 69 species of plant-parasitic nematodes representing 28 genera were extracted from soil and roots. About twice as many nematode spec...
In Uganda, nematodes have the potential to cause substantial yield losses, yet it is not known whether farmers have knowledge of the damage these pests cause. A participatory rural appraisal was therefore conducted to assess farmers' awareness of nematodes, and to determine the preferred traits i...
The damage potential of the plant-parasitic nematodes Pratylenchus coffeae, Helicotylenchus multicinctus and Meloidogyne javanica, was assessed on plantain (Musa spp., AAB-group) cv. Apantu-pa in microplots in Ghana. Hot water treated suckers, planted in 3 l plastic bags containing sterilised soi...
The root-lesion nematode Pratylenchus goodeyi is a common pest of banana in Kenya, which results in significant yield losses. An emerging option for the management of banana nematodes includes the use of endophytic fungi, which cause no damage to their hosts but often extend benefits, such as enh...
Nine Nigerian populations of Scutellonema bradys, obtained from infected yam (Dioscorea spp.), were assessed following inoculation onto susceptible yam (Dioscorea rotundata) cv. TDr131 in pot and field experiments in Nigeria between 2002 and 2004. In addition, geographically separated populations...
Root-knot nematodes (Meloidogyne spp.) are a particularly damaging group of pests on a wide range of crops and the predominant plant-parasitic nematode occurring on cassava (Manihot esculenta). Screening for resistance against these nematodes would be prudent to minimize yield loss and the high c...
The asexual root-knot nematodes (RKNs) (Meloidogyne spp.) exemplified by Meloidogyne incognita are widespread and damaging pests in tropical and subtropical regions worldwide. Comparison of amplification products of two adjacent polymorphic regions of the mitochondrial genome using DNA extracts o...
Aspergillus allahabadii, previously reported only from soils in India and El Salvador, was isolated from root-knot nematode egg masses (Meloidogyne spp.) in vegetable fields in Benin. Three populations were recovered from separate fields in the Guinea savannah region from tomato and/or cabbage. T...
In Benin, yam production continues to face numerous production constraints, including yield and quality reduction by Scutellonema bradys. Implementation of efficient management techniques against this pest requires an improved understanding, including at the molecular level, of the pest. The curr...
