Abstract

The high attack armyworm pests (Spodoptera litura F.) caused the decrease of the vegetables productivity, especially the mustard plant in South Kalimantan. One of the ways in controlling pests is the usage of pesticide. Botanical pesticide could be an alternative to replacing chemical pesticide because of its environmentally friendly nature. Heart-leaved moonseed stem and lime leaf are the plant materials which could be botanical pesticide materials due to the content of alkaloids, flavonoids and limonoids compound that could reduce the spread of pests and increase the death of pests. The study aimed to find out the effect of heart-leaved moonseed stem extract, lime leaf extract and its mixture to the mortality and the death speed of larva Spodoptera litura F. The method used in the study is Complete Random Design with 4 treatment concentrations and 5 times repetition. The concentration treatments given are E0=0% concentration of heart-leaved moonseed stem and lime leaf extracts (control), E1=15% concentration of heart-leaved moonseed stem extract, E2=15% concentration of lime leaf extract, E3=15% concentration of heart-leaved moonseed stem and lime leaf extracts. The study result shows that the heart-leaved moonseed stem extract, lime leaf extract, and its mixture could give effect to the mortality of armyworm larvae with average percentage of mortality each of 46 %, 54 % and 48 %.respectively. On the observation of armyworm death speed shows that the giving of heart-leaved moonseed stem extract, lime leaf extract, and its mixture also gives effect with average percentage of death speed, 0,13., 0,17 and 0,14 worm/day.
