PEMBERIAN TEPUNG DAUN SIRSAK (Annona muricata L.) DALAM MENGENDALIKAN HAMA KUMBANG BUBUK JAGUNG (Sitophilus zeamais M.) PADA BIJI JAGUNG DI PENYIMPANAN
Abstract: Weevil maize
(Sitophilus zeamais M.) is an important pest in corn grain who are storage in
warehouse. The research aims to get effective concentrations of soursop leaf
powder in controlling the weevil maize (Sitophilus zeamais M.) on corn grain in
storage. This research was conducted in the Laboratory Plant Pest, Faculty of
Agriculture, University of Riau using a completely randomized design with 6
treatments and 4 replications. Each experimental unit consisted of 10
Sitophilus zeamais M. in each soursop leaf powder 0% (0 g/100 g corn grain), 2%
(2 g/100 g corn grain), 4% (4 g/100 g corn grain), 6% (6 g/100 g corn grain),
8% (8 g/100 g corn grain), 10% (10 g/100 g corn grain). Data were analyzed
statistically by analysis of variance and least significant difference test at
the advanced level of 5%. The results showed that the concentration of soursop
leaf powder 10% (10 g/100 g corn grain) is more effective in controlling pest
Sitophilus zeamais M. due cause total mortality of 92,5%, the early death for
during 79,25 hours and lethal time 50 during 242,5 hours.
