Diamond Back Moth (DBM) [Plutella xylostella] and two species of aphid such as Indian Mustard Aphid [Lipaphis erysimi] and Green Peach Aphid [Myzus persicae] are found detrimental for the cultivation of cabbage [Brassica oleracea var. capitata]. Different bio-pesticides were reported to be effective in suppressing the population of DBM and aphids infesting cabbage.

Due to minimum infestations of these pests after the application of different bio-pesticides such as cow urine, garlic + chilli extract, neem based insecticide like vanguard, Bacillus thuringiensis var. kurstaki (B.t.k) etc. and incorporation of different inter crop components like garlic (Allium sativum), coriander (Coriandrum sativum), African marigold (Tagetes erecta), fenugreek (Trigonella foenum-graecum), tomato (Solanum lycopersicum) and French...
