Comparative Assessment on the Knowledge, Attitude and Practices of Lafia Metropolis Residents on the use of Dichlorvos in Lafia, Nasarawa State, Nigeria

Abstract

The widespread use and misuse of dichlorvos, an organophosphate insecticide presents an important environmental and ecological problem in Nigeria. The use in both urban and rural areas against insects in residences, farms and storage facilities takes place within Lafia metropolis affecting both target and non-target insect species, and other animals including humans. The aim of the study was to assess the knowledge, attitude and practices of residents of Lafia metropolis on the use of dichlorvos which is one among the numerous pesticides available in the open market. Data collection was achieved using a validated questionnaire distributed in four selected locations within Lafia metropolis in May 2021 and June 2023. Results showed that out of a total of 2,857 respondents, 1,392 (97.62%) had known dichlorvos in 2021 out of which 1,094 (78.59%) had used it themselves, while 1,422 (99.37%) had known dichlorvos in 2023 out of which 1,217 (85.58%) had used it indicating a significant increase in the period of study (p<0.05). Results also indicated that respondents learned to use dichlorvos majorly from family and friends in 2021 and 2023 (p<0.05; p=0.0014), while they applied it to farms, storage facilities and homes (p<0.05; p=0.0063) without protective clothing (p>0.05; p=0.219). Though the respondents indicated willingness to be trained on the proper use of dichlorvos (p<0.05; p=0.0397), the study further recommends constant monitoring of the distribution and sale to minimize any increase in dichlorvos misuse, which can impact negatively on the human health and environment.
