Abstract: An experiment was carried out in the Entomology Experimental Station based-on Agriculture Research Institute (ARI) Tandojam, Sindh Pakistan. In this regard, the Randomized Complete Block Design with three replication and sub-plot size of 3mx3 (9m2 ) was used. However, 7 treatments with three replications i.e. T1=chemical control (confidor), T2=Neem (Azadirachta indica), T3=Akk (Calotropis procera Alton. F.), T4=Tooh (Citrullus colocynthus Schrad. L.), T5=Datura (Datura stramonium) T6=Tabacco (Nicotiana tabacum) and T7=Control (untreated) were effectively used, in this connection, the pre and post-treatment and observations were also be documented. Against Diamondback moth population on cauliflower the first spray results showed that chemical control(confidor) showed highest efficacy (98.88 ), followed by Neem extract (97.23 ), Tobacco extract (95.39 ), Tooh extract (92.19 ), Dhatura (89.79 ) and least efficacy was resulted by Akk extract (80.98 ). After second spray, chemical control(confidor) showed highest efficacy (99.47 ), followed by Neem extract (96.27 ), Tobacco extract (96.44 ), Tooh extract (91.54 ), Akk extract (77.94 ) and the lowest efficacy was resulted by Dhatura extract (69.19 ) against diamondback moth after second spray. Finally, general or best selection of biopesticides against diamondback moth after 1st and 2nd spray, the treatments were ranked as the: chemical control (confidor); neem extract; tobacco extract tooh extract akk extract and dhatura extract one to seven ranked order respectively.
