Abstract

The quest for sustainable health, environmental protection and conservation of beneficial organisms makes the use of biopesticides a desirable option. This research aimed to identify botanicals used in the management of farm and household pest in Plateau State, Nigeria. A cross sectional study was carried out using semi-structured questionnaires and on the spot face-to-face interviews. The main issues captured include the pest, plants used to managed the pest, parts used, cultivation status, availability, effect on pest, formulation methods and modes of application. The quantitative data were analyzed using the Frequency of Citation (FC), Relative Frequency of Citation RFC (%) and Use Value (UV). A total of 45 plant species belonging to 42 genera, 20 orders and 30 families were found to be useful in the management of 15 different pests. The FC, RFC(%) and UV values identified the most popularly used plants as: Hyptis suaveolens, Vernonia amygdalina, Azadirachta indica, Canarium schweinfurthii and Euphorbia unispina and Erythrophloem africanum. Plants that showed broad activity include Azadirachta indica (7 uses), Erythrophloem africanum, Khaya senegalensis and Vernonia amygdalina. The perception of the respondents indicated that most of the biopesticides are available, affordable, effective, eco-friendly and safe. This survey provides a pathway for formulation of biopesticides.
