Abstract:
Castor (Ricinus communis L.) belonging to the family Euphorbiaceae is the most important non edible oilseed crop of arid and semiarid regions of India. Though castor is seriously affected by many diseases, wilt caused by F. oxysporum f. sp. ricini is an important destructive disease of Saurashtra region of Gujarat. Experiment was conducted to find out effective fungicides for the management of castor wilt. Different fungicides were tested against Fusarium oxysporum f. sp. ricini viz., systemic, non-systemic and ready-mixed fungicide. In laboratory screening of different fungicides, thiram 75% WP (87.24%) was found to be quite effective in inhibiting the radial growth of test pathogen among non-systemic group of fungicides, while in systemic group of fungicides, carbendazim 50% WP (100%) and in case of ready-mixed fungicides carbendazim 12% + mancozeb 63% WP (88.33%) were significantly inhibited the growth of F. oxysporum f. sp. ricini under in vitro.
