Abstract

This research aimed to evaluate the effectiveness of suren toon and soursop
leaves extracts as botanical insecticides against P. xylostella. The research was
conducted using an experimental method with a Completely Randomized Design
(CRD) consisting of eight treatments: P0 (control, 100 ml of distilled water), P1
(chemical insecticide Emamectin Benzoate Cyclone 5.7 WG with a concentration
of 0.5 g/L), P2 (10% suren toon), P3 (20% suren toon), P4 (10% soursop), P5 (20%
soursop), P6 (combination of 5% soursop + 5% suren toon), and P7 (combination
of 10% soursop + 10% suren toon), each with three replications. The application
method used was the leaves-dipping method, where cabbage leaves that had been
dipped in the extract solution were given as larval feed. The observed parameters
included mortality of P. xylostella larva, percentage of pupae formed, percentage of
imago formed, time for larva becoming pupae, time for pupae becoming imago,
feeding activity, effectiveness of botanical insecticides. Observation data were
analyzed using orthogonal contrast test analysis. Suren toon leaves extract and
soursop leaves extract have a significant effect on the mortality and development
of cabbage caterpillars (Plutella xylostella), with optimal concentration is the
combination of suren toon and soursop leaves extracts at 10% concentration.
Keywords: Suren toon leaves extract, Soursop leaves extract, Plutella xylostella,
