Abstract


Cashew tree (Anacardium occidentale L.) is a plant of great economic value not only to growers but other players in the val-ue chain. The crop is mostly cultivated for the nut and can thrive in many agro-ecologies of Nigeria. A case study survey of major cashew plantations and soils of major growing areas in North Central, Nigeria comprising of Oro (Kwara State) and Ejule (Kogi States) showed typical symptom of dieback on cashew panicles re-corded in around 35% and 45% of established cashew trees in the plantations respectively. This disease situation typically referred to as inflorescence dieback of cashew in Nigeria, and this also oc-cur on cashew seedlings both in the nursery and newly established fields. This disease condition and incidence has earlier been as-sociated with Lasiodiplodia species, while the isolated fungi from the soil have priorly been classify as Trichoderma harzianum. The molecular study in this situation depicts the organisms as Cophin-forma atrovirens and Trichoderma ghanense respectively in which very close morphological resemblances were observed
