Abstract Aflatoxins are highly toxic carcinogens produced by several species in Aspergillus section Flavi. Strains of A. flavus that do not produce aflatoxins, called atoxigenic strains, have been used commercially in North America as tools for limiting aflatoxin contamination. A similar aflatoxi...

The burrowing nematode of banana, Radopholus similis, is difficult, if not impossible, to control effectively. The lack of resistance in commercially acceptable cultivars and the perennial nature of the crop limit management options. Multiple-cycle treatment with systemic nematocides is presently...

Maize samples were collected during a survey in three agro-ecological zones in Nigeria to determine the distribution and aflatoxin-producing potential of members of Aspergillus section Flavi. The three agro-ecological zones were, Derived Savannah (DS) and Southern Guinea Savannah (SGS) in the hum...

In 1990, observations were made on the nematode species profile on bananas in Oyugis district, Kenya. The country-wide survey was conducted in 1993 across 13 primary Musa growing districts. Observations were made on banana cultivars Nakyetengu (AAA) and Sukali Ndizi (AB). Considerable variation i...

Banana (Musa spp.) is a vegatatively propagated crop and the type of planting material is of great importancefor the productivity of banana plantations. Traditionally, sucker derived planting materials havebeen used to establish banana plantations but there is a risk of transmitting pests such as...

Fungal endophytes, specifically, Trichoderma asperellum, Beauveria bassiana and Metarhizium anisopliae; strains M2RT4, S4SU1 and S4ST7, respectively, are known to deter aphid infestation and damage to leguminous crops, but no research exists on their biochemical profiles and effects on French bea...

By 2050, Africa's population is projected to exceed 2 billion. Africa will have to increase food production more than 50% in the coming 50 years to meet the nutritional requirements of its growing population. Nowhere is the need to increase agricultural productivity more pertinent than in much of...

Fungal communities in soils of Nigerian maize fields were examined to determine distributions ofaflatoxin-producing fungi and to identify endemic atoxigenic strains of potential value as biologicalcontrol agents for limiting aflatoxin contamination in West African crops. Over 1000 isolates belong...

Aflatoxin contamination resulting from maize infection by Aspergillus flavus is both an economic and a public health concern. Therefore, strategies for controlling aflatoxin contamination in maize are being investigated. The abilities of eleven naturally occurring atoxigenic isolates in Nigeria t...
