Abstract

The aims of this research were to determine the effect of organic ash and antagonistic fungi on controlling tomato Fusarium wilt. Factorial Completely Randomized Design has been used in hisresearch. There were paddy husk and legume ash as organic ash factor, and T. harzianum and Gvirensasantagonistic fungi factor. The result showed that combination of antagonistic fungi (Tharzianum and G. virens) and organic ash (paddy husk and legume ash) could suppress the disease growth, incubation period, disease severity, and disease rate. The effectiveness of the combination were about 36.79-43.30%.

Abstract

Penelitian ini bertujuan untuk mendapatkan isolat bakteri antagonis Bacillus sp. dan Pseudomonas fluorescens dari perakaran tanaman tomat yang secara in vitro memiliki kemampuan kitinolitik, mampu menekan Fusarium oxysporum pada tanaman tomat secara invitro, dan memiliki kemampuan untuk menekan penetasan telur nematoda. Penelitian dilakukan di Laboratorium Mikrobiologi Fakultas Pertanian Universitas Jenderal Soedirman. Hasil penelitian menunjukkan bahwa (1) Bacillus sp. dan Pseudomonas fluorescens yang berasal dari perakaran tanaman tomat bersifat kitinolitik, (2) kedua bakteri tersebut dapat menekan pertumbuhan F. oxysporum secara invitro sebesar 3,22-66,67%, dan (3) kedua bakteri tersebut secara in vitro dapat menghambat penetasa telur Meloidogyne sebesar 17,15-64,85%.

Abstract

This research aimed at knowing 1) phenolic compound contents in the liquid, 2) kinds of tree dust as raw material of the liquid potentially, and 3) the liquid concentration effectively inhibiting growth of Fusarium oxysporum and Meloidogyne spp. in the laboratory. Both in vitro test of the liquid on F. oxysporum and the liquid test potentially on Meloidogyne spp. were designed by Randomized Block Design arranged with factorial. The first factor from the in vitro test was saw dust of albasia, waru, johar, or coconut trees and the second one was the liquid concentration, i.e., 0, 1, 2, or 3 percent. From the second test, the first factor was the same material and the second one was the concentration. Result of the research showed that 1) the liquid from waste of johar tree contained the highest phenol as 4,273.05 ppm, 2) the liquid from waste of albasia, waru, johar, and coconut trees potentially controlled the nematode in the laboratory with mortality up to 50%, while the most potential in inhibiting F. xysporum was the liquid from coconut tree, 3) concentration of was the best concentration in inhibiting F. oxysporum with the highest growth inhibition of colony diameter and dry weight was 90.23 and 90.04%, respectively, while concentration of 4% was the best concentration in resulting nematode mortality at the laboratory as 83.799%.
