Abstract
This study aimed to determine the concentration comparison of the combination of soursop and lemongrass leaves extract that is most effective as a vegetable biopesticide against the death of leaf caterpillars (Plutella xylostella) in mustard plants (Brassica juncea (L) and leaf caterpillars (Spodoptera plusia hymenia) on spinach (Amaranthus sp). This research was an experimental study using a Completely Randomized Design (CRD) consisting of 1 factor, namely the concentration of a combination of soursop and lemongrass leaves extract with three treatments. Namely T1 (100 soursop leaves + 100 grams of lemongrass leaves), T2 (75 soursop leaves + 50 grams of lemongrass leaves, T3 (50 soursop leaves + 150-gram lemongrass leaves), which was repeated three times on mustard and spinach plants. If there were a significant difference, the treatment would be continued with a different test at the level of 95% and 99% The results showed the effect of combination of soursop and lemongrass leaves extract in T1 treatment was higher because of death of caterpillars (Plutella xylostella) as many as 25 tails then T3 with mortality of 14 leaf caterpillars and the lowest effect was T2 treatment with penalty of 13 tail caterpillars. In contrast, the end of leaf caterpillars (Spodoptera plusia hymenia) in the T1 treatment was 25 tails, which was higher than T2 and T3, which only 14 tails, respectively.
