A field survey in the farmers’ fields at Gurugram in Haryana, in few blocks focused on the incidence of pests of cabbage and cauliflower during rabi, 2017-18 and 2018-19. These revealed the occurrence of Plutella xylostella and Spodoptera litura. Maximum number of larvae of P. xylostella and S. litura was recorded in Pataudi block as compared to those of Farukhnagar, Sohana and Gurugram. Seven neem-based biopesticides were evaluated along with check carbosulfan at hot spots. Data revealed that NSKE 5% was quite effective followed by Nimbicidin and Neemgold. The cost benefit ratio was maximum with NSKE (1:9.41, 1:9.53 for cabbage and cauliflower, respectively) followed by neem leaf extract (NLE) with (1:7.72 and 1:6.31). These results conclude that NSKE and NLE can be recommended against major pests of cabbage and cauliflower.
