Farmers perception of problems in the cultivation of selected leaf vegetables in South Western Nigeria

Abstract

The development of alternative strategies for sustainable pests’ management in vegetable production (using insecticides of plant origin) is particularly important in a country like Nigeria where synthetic insecticides are not readily available and farmer s are poorly equipped to handle them. This research was conducted to unravel farmers’ perception of insect pest activities as a constraint to vegetable production and to ascertain the most important pests and indigenous methods of control (using plant extracts). Baseline surveys were conducted using well structured questionnaire on farmers’ plots in farming communities of Akure North and South Local Government Areas of Ondo State. Results from the study affirmed, that all the farmers had the problem of pests on their farms. They have ranked Podagrica sjostedti, P. uniforma, Sylepta derogata, Dsydercus superstitiosus, and Zonocerous variegata as the most important insect pests of the selected leaf vegetables: Amaranthus hybridus, Celosia argentea, and Corchorus olitorius. The results further indicated that 76% of the farmers were aware of the use of indigenous methods of control (using different plant extracts) for the control of pests. The study showed that there was no significant association between education and the use of plant extracts. However, age, sex, and farming experience influenced the use of the plant extracts for insect pest control on the respondents’ farm.
