Larva Grayak (Spodotera litura F) is to first injection that broke to other field plant such as soybean, rice, corn, vegetable, Ricinus communis, etc. exterminate with used synthetic pesticide finally that to be problem such as that to negative result, to human until circle. At this time, to know that to strive for used insecticide concerning plant. Used from plant is insecticide concerning plant substance active result, is once alternative that to broke milted for circles, for example leaf bandotan (Ageratum conyzoides L.). Leaf Ageratum conyzoides L. is one plant have to precocene unsure, it have function is insecticide. Because leaf Ageratum conyzoides L. have insecticide substance and biodegrable characteristic, to become calm for circle, various concentration leaf bandotan extract (Ageratum conyzoides L.) for larva grayak mortality (Spodoptera litura F.) This purpose riset is to know about impact gives concentration various leaf Ageratum conyzoydes L. extract for Spodoptera litura F. mortality with purpose to know about concentration various leaf Ageratum conyzoides L. extract that very maximum for Spodoptera litura F. The experiment was arranged in completely randomized design (CRD), with six replication, is that 0 ppm, 70 ppm, 80 ppm, 90 ppm, 100 ppm, 110 ppm, and 4 replication. Place riset and time in chemistry laboratory at April 14’ until may 3’ 2008. Population is Spodoptora litura F. larva that fertile in “Balai Penelitian Tanaman Tembakau and Serat (BALITTAS) In Malang”. Sample total 240 larvas at every instars (instar 1 until instar 6). Analysis data to used anava one direction and continue test with Duncan test 1 %. Result analysis anava to indicate if Fhitung > Ftable at significant (0,01) standard, that to indicate there different fact impact give various concentration leaf Ageratum conyzoides L. extract for Spodoptera litura F. mortality. At 100 ppm concentration leaf bandotan extract have to give same effectivity with high concentration is that 110 ppm, to became 100 ppm can use to killed larva Spodoptera litura F.
