Rice blast is a worldwide problem in rice and is dangerous because of its yield loss potential ranging up to 100% under favorable conditions. The disease is generally considered the most important worldwide disease in all the rice growing regions of the world and has been reported in more than 102 countries across the globe. The aim of this research was to determine the relative efficiency of Five fungicides used for the control of rice blast viz., Z-force (Mancozeb 80% WP), Dress force (Imidacloprid 20%, Metalaxyl-M 20% and Tebuconazole 2%), Seed care (Imidacloprid 10%, Thiram 10% WS), Blast force (Isoprothiolane 40% WP) and Hexacal (50g Hexaconazole per liter) under in-vivo conditions. The experiment was conducted in pots and laid out in a Completely Randomized Design (CRD) design with 3 replications, 5 treatments, and a control. During the research, it was observed that low incidence of disease (ID) was recorded in all the five fungicides (treatments) used compared with control pots which recorded the highest percent disease incidence of rice blast disease. This connotes that all five fungicides were effective in the control of rice blast in-vivo.
