Agricultural pest management studies

Mosaic virus disease is transmitted by several types of viruses such as OMD, OYVMV, OLCV, CLCuGV, and CYCrV. Among these viruses, some of them are significant threats to okra production worldwide. To develop an integrated pest management strategy against this disease, this seroprevalence study was conducted at the Rural Polytechnic Institute (RPI) of Katibougou, Koulikoro region, Mali. Symptomatic leaves of okra plants were collected in Koulikoro. The symptoms were mosaic associated or not with other symptoms. For this purpose, 52 symptomatic samples and 3 asymptomatic samples collected in the villages of Niarébougou, RPI Katibougou, and Diakitébougou were analyzed. The DAS ELIZA Okra Mosaic Virus (OkMV) kit was used. Among the symptomatic samples, the analyses showed the presence of 13 positive samples. This indicates a prevalence of 25% in the study area. Okra is infected by the okra virus disease called Okra Mosaic Virus (OkMV), which is the first time in Mali to be detected by the ELIZA test. This study shows the prevalence of the okra mosaic virus in Mali and more precisely in Koulikoro. This study shows the importance of keeping OKMV in consideration among the threats to okra cultivation in this area. Key words: Seroprevalence, okra mosaic virus, Mali.
