Integrated pest management practices and pesticide residues in Okra aming farmers in Kwara State

Abstract

Integrated pest management (IPM) is a sustainable approach for minimizing the negative impacts of pests on crops while reducing reliance on synthetic pesticides. This study was conducted in Kwara State Nigeria in 2023, to investigate the effects of implementation of IPM practices on the occurrence of pesticide residues in okra cultivated by the farmers in Kwara State, Nigeria, and identify the factors affecting the use of IPM practices for pest control in okra production. A sample of 245 okra farmers was selected across 4 agricultural zones of Kwara State using a multistage sampling technique. Additionally, okra samples were collected from the farmers of each community of the local government areas. The data collected from the farmers were analyzed using descriptive and inferential statistics including frequency count, percentage, mean, standard deviation, and Pearson product moment correlation (PPMC). The collected okra samples were taken to the laboratory for pesticide residue extraction and analysis was performed using gas chromatography (GC)-mass spectrometer (MS). The results showed that most okra producers in Kwara State were smallholder farmers who, despite practicing IPM, had limited knowledge of the technology. Some pesticide residues were detected in okra, out of which two were present in quantities above the maximum residue limit, while others were below the maximum residue limit. Therefore, this study recommends that the government should improve extension services in the State by providing adequate funds and training extension agents who can provide comprehensive training to farmers on the types and application of IPM as an eco-friendly technology for preventing pesticide residue in okra
