Abstract

Four contact fungicides, Blitox (copper oxychloride), Kocide (copper hydroxide), Mancozeb (dithane M-45) and Bordeaux mixture and four systemic fungicides, Baycor (bitertanol), Calixin (tridemorph), Contaf (hexaconazole) and Bavistin (carbendazim) were evaluated against Phomopsis theae under in vitro condition. The results indicated that carbendazim was found to be the most effective in suppressing the growth followed by dithane M-45. Among the different concentrations tested, carbendazim at 4 ppm and dithane M-45 at 8 ppm were found to be optimum for the control of pathogen’s growth.
