The major economic field diseases of cowpea in the humid agro-ecologies of South-western Nigeria

Abstract

Cowpea, which has now become an important protein source for the teeming populace of Nigerians especially those living in the humid agro-ecological zones of South-western Nigeria, is severely attacked by diseases. The causal agents of these diseases find the environment more conducive for
survival and hence induce disease conditions in the host plant causing significant yield reduction. This paper reviews the present situation of the cowpea diseases in the humid forest agro-ecologies of South-western Nigeria.
