Abstract

The experiment was conducted in the laboratory and field of Spices Research Centre, BARI, Shibganj, Bogra, Bangladesh during Rabi season of 2014-2015 to test the efficacy of some new fungicides in controlling anthracnose/die-back disease and increase yield of chilli. Nine new fungicides and one control were used as treatments. In vitro tests, Orion 72 WP (0.2%) significantly inhibited the radial mycelial growth of the pathogen (Colletotrichum capsici) in the PDA culture media. All the new fungicides significantly decreased the % leaf infection, % leaf area diseased (LAD), % twig infection, % fruit infection, % fruit area diseased (FAD) and increased fresh yield of chilli. Among the fungicides, Orion 72 WP showed the best performance.
