Evaluation of farmers' knowledge about prevailing nematode pests of rice in south-western Nigerian rice production systems

The management of nematode pests in rice cultivation is a critical challenge in Nigeria, exacerbated by the limited knowledge and awareness among farmers. This study aims to evaluate farmers' knowledge and identify gaps that could be addressed to improve pest management practices. A stratified random sampling technique was adopted for this study and a total of 200 rice farmers were randomly selected from 20 villages within the three states (Ogun, Oyo, and Ekiti). A structured questionnaire was administered to collect information on the farmers' demographic characteristics, knowledge of nematode pests, and prevalence of nematode pest-related issues. Findings revealed that a significant majority of the farmers (64.5%) are unaware of nematode pests affecting their crops. Furthermore, majority of the rice farmers (66.5%) rely on chemical nematicides as their primary method for controlling pest infestations. The lack of awareness and knowledge among farmers contributes to yield losses and economic setbacks. Strengthening agricultural extension services and increasing research efforts are vital steps toward improving nematode management and ensuring the sustainability of rice production in Nigeria.
