Abstract

This study aims to determine the effect of kenikir leaf extract (Cosmos caudatus) on the mortality of Grayak Caterpillars (Spodoptera litura). This type of research is a laboratory experiment, with the design used is a Completely Randomized Design (CRD) consisting of five treatments and five replications. The treatments were P0 + as a control, P1 with a concentration of 25%, P2 with a concentration of 50%, P3 with a concentration of 75%, and P4 with a concentration of 100%. Data analysis techniques with steps: normality test, homogeneity test and one way anova test. Research Results, based on the One Way Anava calculation, it was obtained that Fcount = 11.40 with Ftable = 4.43. then it can be stated that the value of Fcount> F table then H0 is rejected and H1 is accepted. In the BNJ (Honest Significant Difference) test, the significance level of 1% of the effect of kenikir leaf extract on treatment A 25% (P1) was not significantly different from the concentration of 50% (P2) and 75% (P3), and at treatment D 100% (P4 ) is not significantly different from ACD, the treatment E (P0 +) is very significantly different from ABDE. Conclusion, there is a very significant effect of kenikir leaf extract (Cosmos caudatus) on mortality of armyworm caterpillar (Spodoptera litura), the higher the concentration of insecticide given, the higher mortality of armyworm caterpillar.
