The experimental design used in this study is completely randomized design (CRD) pattern of non factorial consisting of 4 treatments and 4 replications for each treatment  in-vitro and in-vivo, so that for each in-vitro and in-vivo obtained 16 experimental units. The treatment is tested in this study consisted of 4 levels kale extract ie, 5%, 10%, 15% and 20%. In-vitro, the results showed that the leaf extract can inhibit the growth kale C.capsici colony diameter. Diameter lows seen in 20% extract treatment treatment is 28 mm. Meanwhile, in-vivo experiments showed that the mean diameter observations on the highest spot 7 HSA present in 5% of treatment of 7.8 mm and 7 mm at the lowest concentration of 20%.
