Abstract: Cabbage (Brassica oleracea var. capitata L.) is contemplated as second most important vegetable belonging to the family Brassicaceae. The cabbage cultivars are under a great threat for profitable cultivation due to the attack of fungi, bacteria etc. The disease Alternaria leaf spot of cabbage is prevalent in all the cabbage growing states and is one of the major biotic problems, which limits the production of Cabbage and quality of produce. The experiment for management practices on leaf spot of Cabbage using botanicals and bio-control agents was conducted during Rabi(2016-2017).The minimum disease intensity was recorded in foliar sprays of Trichoderma harzianum (24.55 per cent) which also gave maximum yield (38.21 tonn/ha) as compared to Mancozeb 21.27% disease intensity and head yield(44.25 tonnes/ha) (Treated check).Second best treatment was two foliar sprays of Eucalyptus globulus (24.94 %) disease intensity with head yield (31.32 tonn/ha). All the treatments gave best result on fresh weight (Head) Trichoderma harzianum@ 2.0% (1.53kg) as compared with Mancozeb @ 0.2% (1.77kg) (Treated check).
