ABSTRACT
The main pest that attacks the sweet corn plant is the sweet corn cobs mover
(Helicoverpa armigera Hubner. Pest control can be done using botanical insecticide
babadotan plants (Ageratum conyzoides L.). The aim of this research was to get a
effective concentration of babadotan leaf flour extract against of H. armigera larvae in the
Laboratory. The research was conducted at the Plant Pest Laboratory, Faculty of
Agriculture, University of Riau. The research used a completely randomized design
(CRD) with five treatments and fout replications. The treatments given were several
concentrations of babadotan leaf flour extract 0%, 0.25%, 0.50%, 0.75% and 1%. The
parameters observed were changes in behavior and morphology, initial time of death
(hours), Lethal time 50 (hours), daily mortality (%), total mortality (%) and Lethal
concentration (%). Variance results were further tested with Duncan's New Multiple
Range Test (DNMRT) at 5% level. The results showed that the concentration of
0.75% babadotan leaf flour extract was an effective concentration that could cause
total mortality of H. armigera larvae at 82.50% with an initial time of death of 8.75
hours and Lethal time 50 of 42.75 hours after application. The proper concentration of
babadotan leaf extract to kill 50% and 95% is of 0.14% is equivalent to 1.4 ml.1-1 of
water and 2.59% is equivalent to 25.9 ml.l-1 of water.
