Abstract:
Cabbage is the most abundantly consumed vegetable crop among the crucifers globally. Black rot disease (Xanthomonas campestris pv. campestris) is the principal yield-limiting and destructive pathogen affecting worldwide cabbage production. The use of eco-friendly management practice is of paramount importance to residue toxicity on the host, environmental pollution and harmful effect on consumer's health. The present study consists of eighteen different botanicals for black rot disease management under in-vitro conditions. Highest per cent inhibition was showed by tulsi leaf extract (31.58 mm) followed by mint (26.35 mm) and garlic (18.71 mm) and the lowest per cent inhibition was observed with leaf extract of galanga (9.56 mm). In vivo evaluation of Tulsi leaf extract (at 10%) known to reduce 84.77 per cent disease incidence as compared to control and recorded maximum plant growth and yield parameters.
