Effect of various hot pepper diseases management tools on seedling emergence, wilt incidence and yield of hot pepper was studied as part of integrated management strategies under both fungicide treatment and seedbed types. Different fungicides were tested against the hot pepper diseases. The fungicides viz, Apron star (seed treatment) and Mancozeb which were found effective under field conditions. Seed treatment followed by seedling treatment with fungicides proved ineffective in controlling hot pepper disease, however, besides seed treatment and seedling treatment when fungicides were sprayed at crown region of the plant, hot pepper diseases were significantly reduced. The effect of seed treatment, different seed bed types and fungicide applications methods were affected the performance of Hot pepper. Seed bed types had significant effect on Days to 50% emergence, Days to 50% flowering, Days to 90% physiological maturity, plant height, NFPP, FL and DFY of Hot pepper. Integration of Apron star + Mancozeb with different seedbed types also proved superior compared to their individual treatments. The applied fungicides were significantly affect severity of hot pepper diseases when compared with unsprayed check. The maximum mean severity of Cercospora leaf spot, Bacterial leaf spot, Fusarium wilting, Blossom end rot and Anthracnose were recorded on the unsprayed plots with Mancozeb 80WP at flat and furrow seedbed types, while the lowest mean severity were recorded on the plot sprayed with Mancozeb 80WP at ridge seedbed type at Bure and Dabo Hana districts. Seed treatment with Apron Star followed by seedling treatment and foliar spraying of fungicide Mancozeb 80 WP at recommended rate (after transplanted with interval of two weeks) and sowing of hot pepper on raised seedbed and transplanted on Ridge seedbed can be applied to manage the devastating Hot pepper diseases.
