Efikasi Beberapa Serbuk Nabati Sebagai Insektisida Terhadap Sitophilus zeamais Motsch Pada Jagung di Penyimpanan

Abstract

Abstrak. Insektisida nabati adalah insektisida yang berasal dari tumbuhan dan insektisida itu sendiri adalah
bahan yang dapat digunakan untuk mengendalikan populasi Organisme Pengganggu Tanaman (OPT) terutama
pada masalah penanganan pasca panen tanaman jagung. Hama Sitophilus zeamais M merupakan hama yang
menyerang biji jagung sejak di lapangan dan di penyimpanan serta tingkat serangan S. zeaimais bersifat
merugikan. Beberapa tumbuhan berpotensi sebagai insektisida nabati terhadap hama S. zeamais adalah daun
babadotan (Ageratum conyzioides L), bunga cengkeh (Eugenia aromatica), daun mimba (Azadirachta indica)
dan daun sirsak (Annona muricata L.). Penelitian ini menggunakan Ranangan Acak Lengkap (RAL) faktor
tunggal dengan 5 pasang imago diinfestasikan pada 10g masing-masing serbuk nabati dan 100g biji jagung.
Hasil penelitian menunjukkan bahwa serbuk bunga cengkeh efektif pada pengamatan persentase daya repelensi
tertinggi yaitu 98,33% 2 jam setelah aplikasi, mortalitas tertinggi yaitu 85% 8 hari setelah aplikasi, lama imago
muncul 9,17 (hari ke-55), jumlah imago muncul paling sedikit yaitu 0,33% dan kerusakan biji terendah yaitu
0,46%.

efficacy of several types of vegetable powder as an insecticide against Sitophilus
zeamais motsch pests in corn stored

Abstract. Biopesticide are insecticides derived from plants and insecticides themselves are materials that can be
used to control the population of Plant Pest Organisms (OPT), especially on the problem of handling after
harvesting corn crops. Sitophilus zeamais M pest is a pest that attacks corn seeds since in the field and is stored
and the level of attack of S. zeaimais is detrimental. Some plants that have the potential as vegetable insecticides
against S. zeamais pests are babadotan leaves (Ageratum conyzioides L), clove flowers (Eugenia aromatica),
neem leaves (Azadirachta indica A. Juss) and soursop leaves (Annona muricata L.). This study uses a
completely randomized single design (RAL) single factor with 5 pairs of imago infested in 10 g of each
vegetable powder and 100 g of corn seeds. The result showed that the clove flower powder was effective in
observing the highest percentage of repelency power which was 98.33% 2 hours after application, the highest
mortality was 85% 8 days after application, imago duration appeared 9.17 (day 55), the number of imago
appeared the least is 0.33% and the lowest seed damage is 0.46%.
