Abstract: Cabbage is one of the cruciferous vegetable plant grown across the world.  A large number of insect pests attack on them but butterfly larvae (Pieris brassicae) is one of the most serious one. The current study was conducted at farmer field Malam Jaba Swat. The experiment was Randomized Complete Block Design (RCBD) with three replications and having five treatments along with control. Total three spray were applied at seven days interval. The insecticides combination of botanical extracts and cow urine viz; Lemongrass (Cymbopogon citratus) + cow urine @ 10%, Neem leaves extract (Azadirachta indica) + cow urine @ 10%, White top weed (Parthenium hysterophorus)+ cow urine @10%, Chinaberry (Melia azedarach) + cow urine @ 10% were applied against cabbage white butterfly larvae. The results revealed that the lowest mean infestation and mean percent reduction per plant after different treatments was recorded in plot (Chinaberry + cow urine (1.72), (75.40%), followed by Lemongrass+ cow urine, Neem leaves extract+ cow urine, White top weed+ cow urine (2.33), (57.10)%, (2.60),( 48.65%)  and (2.82), (40.61%)  respectively). The highest mean infestation (4.18) of cabbage larvae/plant was recorded in control plot. The maximum yield was recorded in plot treated with Chinaberry + cow urine (41.50), trailed by White top weed + cow urine, Lemongrass + cow urine, Neem leaves extract + cow urine (29.73, 27.03 and 23.07 respectively). While the minimum yield kg/plot (18.20) was recorded in control plot. It is concluded from the current experiment that all the combination of different botanical extracts with cow urine showed their efficacy against infestation of   cabbage butterfly. But the combination of Chinaberry + cow urine showed better results in percent reduction of cabbage larvae population and the production of cabbage. It is recommended that the combination of Chinaberry + cow urine is superior as compared to other combinations.
