Shallots (Allium ascalonicum Linn) are one of the leading horticultural crops. The
main problem in shallot cultivation is the attack of the beet armyworm (Spodoptera exigua
Hubner). S. exigua attacks can cause production losses of up to 100% if not controlled
properly. The use of botanical pesticides from jengkol rind extract (Pithecellobium lobatum
Benth) is a solution to control beet armyworms (Spodoptera exigua Hubner). This6 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
study used a completely randomized design (CRD) with five treatments of jengkol rind
extract concentration, each treatment was repeated four times so that 20 experimental units
were obtained. 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.
Keywords: Pithecellobium lobatum Benth, Spodoptera exigua Hubner, Botanical
