Capsicum is an important vegetable crop of Karnataka. Among the various diseases affecting capsicum, Phytophthora root rot (Phytophthora capsici) and root-knot nematode (Meloidogyne incognita) infestation are considered as the most destructive under protected cultivation. Totally six fungicides and seven bioagents were screened against P.capsici under in vitro. Among the fungicides, Bordeaux mixture and Metalaxyl MZ were highly inhibitory to P. capsici. Among the antagonists, Trichoderma were most effective in inhibiting the growth of P. capsici. Least inhibition was noticed with Bacillus sp followed by Pseudomonas.  Effect of various disease management tools on seedling emergence, Phytophthora root rot incidence and root knot index were studied. As part of integrated management strategies an investigation was carried out to manage the disease through soil application of fungicide, nematicide and bioagents. Metalaxyl MZ significantly reduced the Phytophthora root rot incidence of 69.23% disease reduction over control under polyhouse condition. Integration of Carbofuran + P. lilacinus (0.33) also proved superior in managing root knot disease over control.
