ABSTRACT
Spodoptera frugiperda J.E Smith is the primary pest that can reduce maize
output. Soursop leaf is a botanical pesticide that can be used to control it
(Annona muricata L.). The purpose of this study was to determine the most
effective concentration of soursop leaf powder extract on fall armyworm mortality
(Spodoptera frugiperda J.E Smith). This research was conducted out in the Plant
Pest Laboratory, Faculty of Agriculture, Riau University, Pekanbaru, from July to
September 2021. The experiment was carried out using a completely randomized
design with 6 treatments and 4 replications. Concentrations of 0 g.l-1 water, 20 g.l-
1 water, 40 g.l-1 water, 60 g.l-1 water, 80 g.l-1 water, and 100 g.l-1 water were used.
The observation parameters were starting time of death (hours), lethal time 50
(hours), lethal concentration (LC50 and LC95) (%), daily mortality (%), and
overall mortality (%). The results revealed that applying soursop leaf powder had
a substantial effect on killing Spodoptera frugiperda. The effective concentration
for controlling Spodoptera frugiperda was 80 g.l-1 of soursop leaf extract water
because it could induce a total mortality of 80.00 % with an initial time of death of
22.25 hours after application and a fatal time of 50 at 103.00 hours after
application.
