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