On-farm Management of Aflatoxin Contamination of Groundnut in West Africa A Synthesis Report

Abstract

This report summarizes results from on-farm management of aflatoxin contamination of groundnut activities conducted by ICRISAT and IER in Mali, with funding support from CFC. A number of technologies to minimize aflatoxin contamination were tested on-farm with participation of the farmers in two regions of Mali. The technologies included tolerant varieties, soil amendment using farm yard manure, crop residues and lime as well as best-bet harvesting and drying techniques. Applying these technologies resulted in aflatoxin reduction ranging from 70-84%. More than 50% of the farmers applying the technologies are producing groundnut with tolerable levels of aflatoxin contamination (i.e. < 10 ppb). The technologies are being scaledout in Nigeria and Senegal
