Experiments were carried out to evaluate various options to reduce wilting of bananas replanted to rehabilitate farms previously destroyed by Xanthomonas campestris pv musacearum (Xcm). Paring, time taken to cure paring injuries and covering corms with infested or uninfested soil were evaluated. ...

All soybean cultivars grown in Nigeria are highly susceptible to rust (Phakopsora pachyrhizi), a disease that can cause up
to 60-80% seed losses. IITA currently emphasizes development of rust-resistant cultivars for African farmers for whom
host resistance is most economical for disease managemen...

Aflatoxin contamination of major food crops is a serious problem in Senegal. Maize and sesame samples were collected during a survey in five districts located in two agro-ecological zones in Senegal to determine levels of aflatoxin contamination and the distribution and toxigenicity potential of ...

Aflatoxin contamination in maize and groundnut is perennial in Ghana with substantial health and economic burden on the population. The present study examined for the first time the prevalence of aflatoxin contamination in maize and groundnut in major producing regions across three agroecological...

Fusarium species are a significant component of the set of fungi associated with cassava root rot. Yield losses due to root rot average 0.5 to 1 ton/ha but losses >3 ton/ha, an equivalent of 15 to 20% yield, often occur. This paper reviews previous work on cassava root rot and summarizes a few re...

Ochratoxin A (OTA) is a mycotoxin commonly associated with many food and beverage crops grown in tropical and temperate regions. There is no data available regarding OTA contamination of ready for sale cocoa beans in Nigeria. The objective of this study was to assess the levels of OTA contaminati...

Soybean rust, caused by Phakopsora pachyrhizi, is one of the most important constraints to soybean production worldwide. The absence of high levels of host resistance to the pathogen has necessitated the continued search and identification of sources of resistance. In one set of experiments, 178 ...
