UJI BEBERAPA KONSENTRASI TEPUNG DAUN GAMAL (Gliricidia sepium Jacq.) TERHADAP HAMA Sitophilus zeamais M. PADA BIJI JAGUNG DI PENYIMPANAN
Abstract: Corn grain in
storage can be damaged by maize weevil Sitophilus zeamais M. pest. If corn
grain stored juring 6 monts cause damage to reach 85%. The research aims to
find a concentration of gamal leaf powder
that cause mortality of maize weevil S. zeamais M. pest highest at corn
grain in storage. Research has been conducted at the Laboratory of Plant Pests
Faculty of Agriculture University of Riau from October until December 2015. The
research was designed a completely randomized design (CRD) consisting of 5
treatments and 4 replications. The treatments tested were giving some
concentration of gamal leaf powder are 0 g / 100 g of corn grain, 2 g / 100 g
of corn grain, 4 g / 100 g of corn grain, 6 g / 100 g of corn grain, and 8 g /
100 g of corn grain. Data were analyzed statistically by analysis of variance
and least significant difference test at the advanced level of 5%. The result
showed that concentration of 8 g/ 100 g of corn grain can cause mortality of
maize weevil S. zeamais M. pest highest
at corn grain in storage with the early time of death at 44,25 hours after
application, lethal time 50 of 279,50 hours after application and total mortality
is 70%.
