KAJIAN PENGENDALIAN HAMA PENGGEREK BATANG CENGKEH ( Hexamitodera semivelutina Hell. ) MENGGUNAKAN METABOLIT SEKUNDER JAMUR Metarhizium DAN Beauveria DENGAN METODE INFUS AKAR

Abstract

SUMMARY

This research aims to determine the effectiveness of the use of secondary
metabolites of Metarhizium and Beauveria fungi by infusion of roots in clove plants
against H. semivelutina larvae. The results of the study are expected to benefit
farmers in controlling H. semivelutina pests with secondary metabolites of the
fungus Metarhizium and Baeveria in clove plants by means of a root infusion.
The study was conducted in a clove plantation area owned by farmers in Tonsawang
Village, Tobatu District, Southeast Minahasa Regency, North Sulawesi. The
research lasted for 3 (three) months, from February to April 2020. This study used
a Randomized Block Design (RBD) method on farmers' clove plants.
Determination of plants that will be applied to the root infusion is done by looking
at plants that are attacked by H. semivelutina pests by looking at the hole that emits
liquid mixed with feces in the clove plants in Tonsawang Village, Tombatu District.
In this study using secondary metabolites of Metarhizium fungus and Beauveria
fungus in H. semivelutina pest control by means of root infusion.
The results showed that the average effectiveness of the use of secondary
metabolites in controlling H. semivelutina reached 78.52%, with a percentage of
effectiveness of the secondary metabolite of Metarhizium fungus at 81.05% which
was not significantly different from the secondary metabolite of Beauveria that was
75.59%, but significantly different from the control of 10.57 %.
