ABSTRACT=<p>Viral diseases are the main adversaries of country bean (<italic>Lablab purpureus</italic> Lin.) production in Bangladesh. Potyviruses and cucumber mosaic virus (CMV) have been reported in country bean leaves that displayed virus-like symptoms. This study looked at the growth and yield of country bean plants that had been treated with <italic>Trichoderma asperellum</italic> to control country bean viruses. <italic>T. asperellum</italic>-treated plants exhibited decreased disease incidence up to 91% and a drop in the vector population up to 96%, when compared to control plants. Plant growth was enhanced in soil drenched with <italic>T. asperellum</italic> suspension, with an increase in the number of leaves per plant, pods per plant, root length, weight of dried pods/plant, and weight of dried seeds/plant. Finally, our findings suggest that <italic>T. asperellum</italic> could be an effective treatment for controlling viral diseases of the country bean in Bangladesh.</p>
