Abstract

One of the obstacles in providing high quality soybean (Glycine max) seed is the infection of seed-borne fungal pathogens. Micro wave treatment is one of the alternative methods to control the seed-borne pathogens effectively but it needs to be further developed. This research consisted of two stages. The first stage was aimed to determine the best soybean seed moisture content in maintaining seed physiological quality after exposing to micro wave. The second stage was aimed to determine the most effective duration of micro wave exposure to reduce the rate of infection of seed-borne fungal pathogens using the best moisture content resulted from the first stage. The experiment  on seed moisture indicated that 9.20% was the best seed moisture content in maintaining the physiological quality when the seed was exposed to micro wave.  Furthermore, micro wave exposure of 60 seconds was able to control Aspergillus flavus, while the exposure of  80 seconds was able to control Fusarium sp., Curvularia sp., and A. niger.

Abstract

Infection of Onion yellow dwarf virus (OYDV) are reported causing problems in garlic production. Planting virus-free bulbs might help reduce viral disease incidence in the field. This research was aimed to develop method for eliminating OYDV from garlic bulbs using combination of electrotherapy (0, 5, 10, 15, and 20 mA each for 10 minutes) and thermotherapy (23, 28, 33, 38°C each for 4 weeks). Two garlic cultivars, i.e. Sangga Sembalun and Lumbu Hijau were used as seed bulbs for OYDV elimination tests. Virus infection was confirmed using transcription-polymerase chain reaction (RT-PCR).  The result showed that thermotherapy at 33 °Cwas the best method to eliminate OYDV in garlic although the efficiency was not the same for all cultivars. The efficiency reached up to 60% for cv. Lumbu Hijau, whereas for cv. Sangga Sembalun only reached up to 40%. Electrotherapy alone or in combination with thermotherapy were not able to produce OYDV-free plantlets.

Abstract

The use of salicylic acid as resistance inducers agents in several plants species was well known. Salicylic acid has been believed to play an important role in inducing resistance against some pathogen. This research was aimed to study the role and effectiveness of salicylic acid as inducers for the resistance of some rice variety against bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae. The experiment was arranged in completely randomized factorial design with three factors i.e. rice variety, salicylic acid, and pathotypes, each treatment was replicated three times. The results showed that salicylic acid could prolong the latent period of X. oryzae pv. oryzae pathotypes IV and VIII in paddy rice varieties Conde and Ciherang,  induce the resistance of rice varieties as well as reducing the rate of infection of the two mentioned pathotypes. Salicylic acid was also able to induce the resistance of Conde and Ciherang varieties in order to suppress area under disease progress curve (AUDPC)  of X. oryzae pv. oryzae pathotypes IV and VIII.

Abstract

Fusarium wilt disease caused by pathogenic fungus F. oxysporum f. sp. cubense is an important disease in banana plants. This research was aimed to identifiy Fusarium spp. collected from banana plants showing wilt disease based on morphology and molecular characters.  The fungi isolates obtained was further examined for its pathogenicity and distribution in various parts of banana plants.  Based on morphological characters, i.e. growth rate, total conidia, colony color, macroconidium, microconidium, and chlamydospores, F. oxysporum f. sp. cubense can be differentiated from other species of Fusarium, but not the strain. Molecular analysis using specific primers VCG 01213/16 and Foc1/Foc 2 successfully identified 13 and 7 isolates of F. oxysporum f. sp. cubense TR4 and F. oxysporum f. sp. cubense non TR4, respectively.  Analysis using universal primer ITS4/ITS5 identified 7 isolates of F. solani, 1 isolate of F. verticillioides, and 2 isolates non Fusarium.  Infection of F. oxysporum f. sp. cubense TR4 and non-TR4 were found mostly in pseudo stems, whereas F. solani and F. verticillioides dominantly colonized banana corm. Pathogenicity test showed that F. oxysporum f. sp. cubense TR4 and non-TR4 caused necrosis on corm of cv. Ambon Kuning.  Similar necrosis symptom was also observed on infection of F. solani but with less severity.

Abstract

Cowpea mild mottle virus (CPMMV) is one of important virus which infects soybean and become an endemic disease since the first time reported in Java and Sumatra. Research was conducted to study the host range of CPMMV and to evaluate response of new type soybean varieties to CPMMV specific isolate.  Host range study of CPMMV CR16 isolate was conducted by sap transmission method to 11 species of indicator plants, whereas evaluation of soybean response involved 10 varieties.  The resistance response of soybean variety was based on incubation period, and of either  the disease incidence or severity. Virus infection on test plants were confirmed by dot immunobinding assay (DIBA) using specific CPMMV antisera. The CPMMV CR16 isolate was able to infect systemically 8 plant species belongs to Leguminoceae, and Solancaeae; while the virus caused local infection on Amaranthaceae. All plant species infected systemically proved to become sources of inoculum for CPMMV when they used in back inoculation to soybean.  Response of soybean varieties to CPMMV CR16 isolate can be categorized into susceptible (Detam 1, Detam 2, Detam 3, Anjasmoro, Wilis), moderated (Detam 4, Malika, Dena 1) and resistant (Argomulyo and Grobogan).
