Abstract

ABSTRACT Efforts to develop control techniques of gall rust disease caused by fungi,Uromycladium tepperianum still need to be continued. This study aims to examine the effectiveness of different types and doses of copper-based and boron-based fungicide formulations in suppressing gall rust disease on sengon. The results showed that both fungicides tested showed different effectiveness. Treatment of CC fungicide at a dose of 10% with both pruning and non pruning within two months were able to suppress gall rust as many as 4.2 pieces. Meanwhile, treatment of PG fungicide at a dose of 10% with pruningwere able to suppress gall as many as of 4.8 pieces, treatment without pruning was only able to suppress tumor about 1.6 pieces. CC fungicide apparently could be applied to suppress gall rust without pruning treatment while PG fungicide combined with pruning treatment was more effective.ABSTRAKSerangan penyakit karat tumor pada sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) yang disebab- kan oleh fungi Uromycladium tepperianum (Sacc.) Mc. Alpin. masih terjadi di hampir semua wilayah pertanaman sengon di Jawa. Upaya pengembangan teknik pengendalian penyakit ini, seperti pengembangan fungisida alternatif masih perlu dilakukan. Tujuan penelitian ialah untuk mengetahui efektivitas jenis dan dosis fungisida hasil formulasi berbasis tembaga dan boron serta pemangkasan yang dilakukan dalam menekan pertumbuhan penyakit karat tumor pada tanaman sengon. Percobaan dilakukan menggunakan rancangan faktorial dalam rancangan acak lengkap dengan tiga faktor, yaitu pemangkasan, jenis fungisida dan dosis yang digunakan. Fungisida sebanyak 10 ml diaplikasikan pada tanaman sengon dengan metode injeksi batang setiap bulan. Hasil penelitian menunjukkan kedua fungisida yang diuji menunjukkan efektivitas yang berbeda. Perlakuan fungisida CC dosis 10% pada tanaman sengon yang dipangkas dan tidak dipangkas dalam waktu dua bulan mampu menekan karat tumor sebesar 4,2 buah. Pada perlakuan fungisida PG dosis 10% pada tanaman yang dipangkas mampu menekan karat tumor sebesar 4,8 buah, tetapi pada sengon yang tidak dipangkas mampu menekan karat tumor sebesar 1,6 buah. Fungisida CC lebih efektif menekan karat tumor pada sengon yang tidak dipangkas sedangkan pada sengon yang dipangkas lebih efektif menggunakan fundisida PG.

Abstract

Malapari (Pongamia pinnata) is a potential plant for biodiesel and has the ability to grow on marginal land. Malapari cultivation has not yet been carried out due to low economic value. Agroforestry crop patterns are expected to provide intermediate results so that people would be interested in planting malapari. Planting on coastal land requires the right technology to produce optimal growth. This study aims to determine the effect of malapari cropping patterns and evaluate biological fertilizer application in the seedling phase after planting in the field. The research uses a split plot design (Split Plot Design) with the main factors that are the pattern of malapari planting and sub-plots that are the type of application of biofertilizer. The results obtained from the study showed that the interaction of cropping pattern treatment and biofertilizer application did not give significant growth to malapari; the combination of the application of organic manure, Trichoderma spp. and mycorrhiza bio-fertilizers in the nursery yielded the largest malapari diameter growth after planting in the field at the age of 3 years.
