Rhizome rot in ginger incited by Pythium aphanidermatum (Edson) Fitzp is one of the most important diseases which causes qualitative as well as quantitative loss. Pot culture studies were undertaken with the aim to manage rhizome rot disease applying organic and inorganic amendments, under screen house conditions. Among all preventive treatments, maximum average mortality was in Gypsum (51.66%) and Castor cake (48.33%) and Safflower cake (45.00%). However, Neem seed cake was found most effective with least average mortality of 20.25 per cent. The second best amendment was Poultry manure (22.67%) followed by Vermicompost (24.64%), Groundnut cake (31.74%), Cotton cake (32.14%), Compost (36.98%), Soybean cake (42.22%), Safflower cake (45.00%), Castor cake (48.33%) and Gypsum (51.66%) with mortality reduction of 66.64 followed by 63.70, 53.28, 52.71, 45.64, 37.90, 33.79, 28.90 and 24.00 per cent, respectively. Average (PESR + PESM) reduction in mortality was recorded with all oilseed cakes and amendments tested ranged from 24.00 to 70.24 per cent. However, reduction in mortality (70.24%) was recorded with Neem seed cake. Least average per cent mortality was recorded with curative treatment of Neem seed cake followed by Vermicompost and Poultry manure. The maximum average mortality was recorded with gypsum (55.00%), safflower cake and castor cake (51.66%). Average maximum per cent reduction in rhizome rot with the treatment Neem seed cake (60.71%) followed by Vermicompost (49.99%) and Poultry manure (45.83%). Comparatively minimum per cent reduction in damping off was recorded with gypsum (19.52%), safflower cake and castor cake (24.40%).
