Assessment ofAegle marmelosFruit Extracts as Organic Insecticide forSpodoptera exiguaonAllium ascolanicum

Abstract

Allium ascalonicumL. is a commodity household Indonesian consume for daily cooking. However, the constraint on shallot production is attacked bySpodoptera exigua(Hübner, 1808)). So far, farmers have relied a lot on control methods using chemical pesticides, which negatively impact the environment. The fruit ofAegle marmelosL. contains a fatty substance called tannin, one of the compounds with a bitter taste that insects can dislike. This content is whyA. marmelosis highly recommended as an organic pesticide. The study assessed the concentration of A. marmelos extracted which was effective in controlling S. exigua. The study was arranged to use a randomized block design, consisting of five treatments ofA. marmelosfruit extract concentration, namely: 2 mL L–1 of water (K1); 4 mL L–1of water (K2); 6 mL L–1of water (K3); 8 mL L–1of water (K4); 10 mL L–1of water (K5) and withoutA. marmelostreatment (K0). The results showed that a concentration of 4 mL L–1of water effectively suppresses the development ofS. exiguaand can increaseA. ascalonicumproduction.
