Abstract Six systemic and surfactant fungicides viz., carbendazim, ridomil MZ, captan, thiram, copper oxychloride and chlorothalonil were tested for its uptake, translocation and persistence in chilli plant. Systemic fungicides i.e. carbendazim and ridomil MZ were readily absorbed in the chilli plant when applied as seed treatment. While in soil treatment along with systemic fungicides contact fungicides were also easily absorbed by the plant and were translocated to different part till 45 days. Plant extract showed inhibitory activity indicating translocation and persistence of fungicides. Among eight fungicides tested for phytotoxic effect on chilli plants, six fungicides viz. propiconazole, fosetyl Al, difenconazole, tridemorph, mancozeb and coper oxychloride showed phytotoxic effect, when applied at two fold and three fold doses of recommendation. At three fold doses fungicides were more toxic showing adverse effect in the form of drying, necrosis and shredding of leaves and wilting of plants. Carbendazim and Ridomil MZ do not showed ant phytotoxic symptoms on chilli even after sprayed at two fold and three fold doses of recommendation.
