    Cashew is an important fruit tree majorly cultivated for edible nuts which provides income to farmers. Productivity and quality of the nuts are threatened by disease infestation; major fungal disease that affects cashew is inflorescence dieback caused by Lasiodiplodia species. Huge crop losses are recorded and problem intensified due to dearth of information on its management in Nigeria. Carbendazim, Mancozeb, extracts of Ageratum conyzoides, Carica papaya, Chromolaena odorata were used in spray application to manage the disease. Records of dieback incidence, severity index, disease reduction and nut yield were taken. Data were analyzed using SAS and mean difference were compared using Duncan Multiple Range Test. The treatment types showed efficacy to reduce incidence, dieback severity and improved yield. Cashew trees treated with integration of mancozeb with C. odorata was consistently higher in severity but produced highest nut yield in 2013 and 2015 seasons. The nut yield record was higher in trees treated with A. conyzoides and C. papaya-only compared to C. odorata, however cashew nut yield was generally higher in integrated systems. However, most effective system that improved yield were integration of Mancozeb with C. odorata, Carbendazim with A. conyzoides, Carbendazim with C. papaya and integration of Mancozeb with A. conyzoides
