Abstract

Beet armyworm (Spodoptera exigua Hubner) is one of the main problems in shallot cultivation which can cause production losses of up to 100% if not controlled. The use of botanical pesticides from jengkol rind extract (Pithecellobium lobatum Benth) is a solution to control beet armyworms (Spodoptera exigua Hubner). This study aims to obtain a concentration of jengkol rind extract which is effective to controlling beet armyworm. The study was conducted at the Laboratory of Plant Pest and Experimental Garden at the Faculty of Agriculture, University of Riau from January until March 2020. This research was conducted experimentally using a completely randomized design (CRD) with five treatments and four replications. The treatments given were jengkol rind extract concentration   0 g.l-1 water, 25 g.l-1 water, 50 g.l-1 water, 75 g.l-1 water and 100 g.l-1 water. The results indicate that the application of jengkol rind extract 100 gl-1 water is an effective concentration to control beet armyworm with an initial time of death 12.75 hours, a lethal time 50 at 37.50 hours, the highest daily mortality on the second day at 37.5% and total mortality is 92.5% in the 5 days after application.
