PEMANFAATAN Baringtonia asiatica DAN Annona muricata TERHADAP SERANGGA VEKTOR PENYAKIT PADA TANAMAN CABAI

Abstract

Insect vectors disease is a major problem for chilli crop production in North Sulawesi. The effect is significant in decreasing crop production. The use of plant-derived insecticide is potential and environmentally friendly way in controlling the insect, as a form of integrated pest management. Seeds of Bitung (Barringtonia asiatica) and seeds of soursop (Annona muricata) plants can be used as an organic insectiside to control the several types of insect vectors in pepper crop. The purpose of this study was to determine effects of the application of extracts of B. asiatica and A. muricata on the growth of insect vector (Aphis gossypii) in pepper and and determine the extracts's lethal level. This research was conducted in the Green House of Plant Pests and Diseases Department of the Faculty of Agriculture Unsrat Manado, for 6 months time. The research used a complete randomized design consisting of 6 treatments; each treatment was consisted of three replications. The results showed that the percentage of dead insects assay (Aphis gossypii) increased as the concentration of the extract used increased. This study found that the concentration of soursop seed extract at 50 g / l and a concentration of 1.75% Bitung seed extract was the best to be used as a botanical insecticide in controlling the insect population vector (Aphis gossypii) in laboratory conditions. It has an effective lethal concentration for 93, 67% and 90.0% of all test insect population. Overall bioactivity increased the effectiveness of soursop Bitung seed extract as botanical insecticides.

Effectiveness of seed oil formulations of Azadirachta indica (A.) Juss and Barringtonia asiatica (L.) Kurz in controlling aphids (Aphis gossypii glover) on Strawberry (Fragaria x ananassa duch) plants

“…Semua bagian dari tumbuhan bitung diketahui memiliki senyawa saponin yang dapat menghambat aktivitas serangga dan mengakibatkan tingkat kematian serangga mencapai 92,84% (Syahputra & Minarti, 2022). Hasil penelitian Salaki & Pelealu (2012) menunjukkan bahwa ekstrak etanol biji Barringtonia asiatica memiliki efek insektisida terhadap ulat penggerek buah dan ulat tanah pada tanaman cabai. Masturina et al, (2022) juga menjelaskan bahwa ekstrak biji bitung dengan konsentrasi 2% efektif dalam menurunkan kepadatan populasi kutudaun M.sanborni pada tanaman krisan hingga 100%.…”

Aktivitas Antibakteri Fraksi Biji (KEBEN) Barringtonia asiatica L. Kurz pada Staphylococcus aureus dan Escherichia coli

“…Menurut Bustanussalam dan Simanjuntak (2009), biji keben mengandung senyawa glikosida yang mempunyai daya toksisitas (LC 50 ) sebesar 30,19 ppm [7]. Penelitian Salaki dan Pelealu (2012) juga membuktikan bahwa biji keben merupakan insektisida botani yang sangat baik untuk pengendalian populasi serangga Aphis gossypii [11]. Selain itu, ekstrak biji keben memiliki daya penghambatan yang kuat terhadap jamur Curvularia verruculosa [12].…”

The Effectiveness of Azadirachta Indica A. Juss. and Barringtonia Asiatica L. Kurz. Seed Extract to Controlling Macrosiphoniella Sanborni (Hemiptera : Aphididae) on Chrysanthemum Morifolium Var. Jayanti

“…Senyawa saponin bersifat racun bagi hewan berdarah dingin termasuk golongan serangga (Prihatman, 2001). Salaki et al (2012) menyatakan bahwa ekstrak biji bitung dengan konsentrasi 1,75% sangat baik digunakan sebagai pestisida nabati dalam mengendalikan populasi A. gossypii karena dapat mematikan populasi sebesar 90%. Selain itu, ekstrak biji B. asiatica dengan konsentrasi 0,3% dapat menyebabkan mortalitas hama C. pavonana sebesar 86,6% (Dono et al, 2008).…”
