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.
