Sa’adah, Agustina Miftakhus (2018) Efektivitas Aplikasi Fungisida Dan Agens Hayati Terhadap Kejadian Penyakit Pada Luka Bekas Pengambilan Mata Tunas Tanaman Tebu (Saccharum Officinarum L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Teknologi pembibitan sebagai kegiatan awal budidaya tanaman tebu berperan penting untuk menghasilkan tebu yang optimal.Produksi gula saat ini belum memenuhi kebutuhan konsumsi dalam negeri.Adapun kekurangan kebutuhan gula tersebut dipenuhi dengan impor. Salah satu upaya pemenuhan kebutuhan gula dilakukan dengan intensifikasi dengan meningkatkan penyediaan bahan tanam (tebu) menggunakan teknologi baru dari BALITTAS yaitu pengambilan mata tunas dengan bantuan alat bor tanpa harus menebang tanaman tebu tersebut. Namun pengambilan tersebut berpotensi untuk masuknya patogen kedalam tanaman dengan mudah. Sehinggan dilakukan upaya pencegahan secara kimiawi dan hayati dengan Fungisida Nordox 56 WP merupakan salah satu bahan yang digunakan dalam pengendalian jamur di PG Kebonagung sedangkan agens hayatiTrichoderma harzianum dan Aspergillus nigermemiliki potensi untuk mengedalikan patogen tanaman. Penelitian ini terdiri dari metode eksperimen uji perlakuan penambahan fungisida dan agens hayati pada luka bekas pengambilan mata tunas, pengamatan kejadian penyakit dan metode eksplorasi jamur patogen pada luka bekas pengambilan mata tunas tebu masing- masing perlakuan. Kejadian penyakit paling rendah terdapat pada perlakuan penambahan agens hayati T. harzianum, A. niger, dan perlakuan campuran T. harzianum dan A. niger yaitu 0%. Perlakuan Fungisida Nordox 56 WP memiliki kejadian penyakit sebesar 90% sedangan kejadain penyakit tertinggi terdapat pada perlakuan kontrol sebesar 100%. Adapun jamur patogen yang berhasil diisolasi sebanyak 12 isolat, Curvularia sp, Fusarium sp, Nigrospora sp, dan terdapat jamur lain yang sulit untuk teridentifikasi.
English Abstract
Seed technology as an initial activity of sugarcane cultivation is important to produce optimal sugar cane.Sugar production currently does not meet domestic consumption needs. The shortage of sugar needs is filled with imports. One of the efforts to meet the needs of sugar is done by intensification by increasing the supply of planting material (sugar cane) using new technology from BALITTAS, namely taking shoots with the help of drill tools without having to cut down the sugar cane. But the extraction has the potential to enter pathogens into plants easily. It carried out chemical and biological prevention efforts with Nordox Fungicide 56 WP is one of the ingredients used in controlling fungi in PG Kebonagung while the biological agent Trichoderma harzianum and Aspergillus niger has the potential to control plant pathogens. This study consisted of an experimental method of treatment test for addition of fungicides and biological agents to the scars taken from shoots, observation of disease occurrences and methods of exploration of pathogenic fungi in wounds taken from sugar cane shoots of each treatment. The lowest disease incidence was found in the addition of T. harzianum, A. niger biological agents, and the treatment of T. harzianum and A. niger mixture was 0%. Nordox Fungicide Treatment 56 WP has a disease incidence of 90% while the highest disease prevalence is in the control treatment of 100%. As many as 12 isolates of pathogenic fungi were isolated,Curvularia sp, Fusarium sp, Nigrospora sp, and there were other fungi that were difficult to identify.
