This study evaluated the response of four rain-fed lowland New Rice for Africa (NERICA) varieties (NERICA-L-12, NERICA-L-41, NERICA-L-42 and NERICA-L-56) and a popularly grown Oryza sativa (ITA 150) to nitrogen (0, 30, and 100 kg N ha-1). The interactions between nitrogen and variety were not sig...

Frogskin is the most limiting disease of cassava crops in Colombia, causing losses in production up to 90%. Since this disease was associatated with 16SrIII phytoplasma presence, a study was carried out to isolate this phytoplasma using liquid and solid culture media. Root, petiol, stem, leaf and...

Banana (Musa spp.) is the most popular marketable fruit crop grown all over the world, and a dominant staple food in many developing countries. Worldwide, banana production is affected by numerous diseases and pests. Novel and rapid methods for the timely detection of pests and diseases will allo...

In Uganda, banana (Musa spp) and coffee (Coffea spp) form the economic base for a big population of small-scale farmers and provide environmental protection. However, their production is currently declining. The two crops are grown in association as intercrops or adjacent monocultures but little ...

The global yield of bananas, one of the most important food crops is severely hampered by parasites, such as nematodes, which cause yield losses up to 75%. Plant nematode interactions of two banana cultivars differing in susceptibility to Radopholus similis were investigated by combining the conv...

The banana ( Musa spp.) weevil ( Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) is a major pest in East Africa causing yield losses of up to 14 metric tonnes per hectare annually. Laboratory and field experiments were conducted to determine whether the response of the banana weevil, C...

Tephritidae have a major economic importance in the tropical areas. In Benin, we had only very little information available on the mango fruit fly species, except the demonstration of their damage. We therefore carried out the first investigations in Northern Benin during the mango season in 2005...
