Abstract:

This study aims to determine the effect of salt/salinity (NaCl) levels on the growth of Gliocladium sp. (Colony area, dry weight and number of spores) and antagonistic activity of Gliocladium sp. in inhibiting Foc. The research was conducted at the Laboratory of Plant Diseases, Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya. The stages in this study included counting colony area, sporulation and dry weight of Gliocladium sp. with single culture method, antagonism test between Gliocladium sp. and Foc with dual culture method. In the research stage to determine the effect of salt levels used NaCl, with concentrations of 0 gr/l, 4 gr/l, 8 gr/l, 12 gr/l and 16 gr/l. The design method used in this study was a completely randomized design (CRD). Banana plants can grow in tropical climates with a pH of 4.5-7. In banana cultivation there are several obstacles that can reduce banana production, the main obstacle is caused by the attack of the pathogen Fusarium oxysporum f. sp cubense (Foc) which causes banana plants to wilt. Efforts to control the attack of pathogenic Foc, can be done by utilizing the antagonistic fungus Gliocladium sp. The results showed that the colony area, sporulation and dry weight of Gliocladium sp. showed that overall growth increased with increasing salt content used, the results obtained were colony area, sporulation and dry weight of Gliocladium sp. The highest yield was found in the treatment with a concentration of salt content of 16 gr/l, with values of 4.184 cm2, 7.933 spores/ml and 0.132 gr respectively, while the antagonism test between Gliocladium sp. and Foc, the highest inhibition percentage of Gliocladium sp. occurred at a salt concentration of 16 gr/l of 45.556%. The research shows that the addition of NaCl to the media has a positive effect on Gliocladium sp.

Abstract:

Minyak cengkeh dan cendawan Gliocladium sp. diketahui memiliki potensi sebagai agens pengendali cendawan Fusarium oxysporum f. sp. cubense (Foc), penyebab penyakit layu pada tanaman pisang. Pengujian kompatibilitas antara minyak cengkeh dengan cendawan Gliocladium sp. perlu dievaluasi dalam rangka menyusun paket pengendalian terpadu terhadap penyakit layu Fusarium. Tujuan penelitian ialah mengevaluasi pengaruh minyak cengkeh terhadap pertumbuhan koloni cendawan Gliocladium sp. dan daya hambatnya terhadap cendawan Foc ras 4. Penelitian dilaksanakan di Laboratorium Proteksi Tanaman Balai Penelitian Tanaman Buah Tropika pada bulan Mei sampai Juli 2008. Perlakuan terdiri atas minyak cengkeh volume 3, 9, dan 18 µl disusun dalam rancangan acak lengkap dengan lima ulangan. Hasil penelitian menunjukkan bahwa miselium cendawan Gliocladium sp. yang mendapat perlakuan minyak cengkeh masih mampu tumbuh hingga memenuhi ruang cawan petri. Jumlah konidia cendawan Gliocladium sp. yang diperlakukan dengan minyak cengkeh terbukti lebih sedikit dibanding cendawan yang tidak diperlakukan dengan minyak cengkeh. Cendawan Gliocladium sp. yang telah mendapat perlakuan minyak cengkeh masih memiliki sifat antagonistik yang efektif terhadap cendawan Foc. Efektivitas antagonisme cendawan tersebut tidak berbeda nyata dengan efektivitas antagonisme yang tidak diperlakukan dengan minyak cengkeh. Hasil ini memberikan harapan karena minyak cengkeh tidak memberikan efek negatif terhadap aktivitas Gliocladium sp., sehingga dapat dijadikan sebagai salah satu komponen dalam program pengendalian secara terpadu penyakit layu Fusarium pada pisang. Namun masih diperlukan penelitian lebih lanjut mengenai pengaruh minyak cengkeh terhadap pertumbuhan tanaman. Clove essential oil and Gliocladium sp. are known to have the potency for controlling Fusarium oxysporum f.sp cubense (Foc) the causal agent of wilt banana disease. The compatibility of clove oil and Gliocladium sp. has to be evaluated to establish an integrated pest management against Fusarium disease. The objective of this experiment was to evaluate the effect of clove oil on the growth of Gliocladium sp. colony and the inhibition value of this fungus to Foc race 4. The experiment was conducted in the Plant Protection Laboratory of Indonesian Tropical Fruit Research Institute from May to July 2008. The treatments were volumes of clove oil i.e. 3, 9, and 18 µl that were arranged in a completely randomized design with five replications. The results showed that Gliocladium sp. mycelia treated with clove oil could still grow throughout the available space within petridish. However, Gliocladium sp. treated with this oil had lower number of conidia than that it was untreated. Gliocladium sp. treated with clove oil had still effective antagonism trait to Foc. This effectiveness was not significantly different from Gliocladium sp. that was untreated with clove oil. This result indicated that clove oil had good potency as a component in integrated control program against wilt disease on banana, because it did not have negative effect to Gliocladium sp. However, further research is still needed to evaluate the effect of clove oil to plant growth.

Abstract:

The possibilities of using the biological products “Trichodermine” (Trichoderma viride Pers ex Fr.), “Gliocladine” (Gliocladium virens Miller et al.) and the mycorrhizal activator “Rhizo VAM Basic” (Glomus intraradices Schenck&Smith) for control of fungal diseases in garden pea and and their impact on the biometric indicators of young plants were studied. Biological preparations based on antagonistic fungi Trichoderma viride and Gliocladium virens improve the phytosanitary condition of the plants, the mycorrhizal fungus Glomus intraradices stimulates the formation of the root system and tuber formation, but has a weak fungicidal effect against Fusarium wilt in this culture. The experiment was performed on an artificial infectious background by Fusarium oxysporum Schlecht. f. sp. pisi (Hal.) Raillo, isolated from diseased plants. The effect of application of the biological products“Trichodermine” and “Gliocladine” is 34-68%, from “Rhizo VAM Basic” - 8% compared to the infected control. The combined application of biological preparations with fungicidal and mycorrhizal action significantly protects the crop from infection with the causative agent of Fusarium wilt of garden pea.

Abstract:

Algunos géneros fúngicos han sido utilizados para el control de agentes causantes de enfermedades en plantas, por lo que su actividad representa una alternativa para la disminución e incluso la sustitución de químicos sintéticos. Existen hongos antagonistas ampliamente estudiados, como Trichoderma sp., que concurre con otros hongos que poseen un alto potencial como agentes biocontroladores, entre ellos se destaca Gliocladium sp. En este estudio se pretende establecer la capacidad antagonista que tiene Gliocladium contra el patógeno causante de la pudrición blanca de la cebolla, Sclerotium cepivorum. Se logró aislar Gliocladium sp. a partir de una muestra de suelo dedicada al cultivo de cebolla (Allium cepa L.), se subcultivó hasta obtener un cultivo axénico y se realizaron cultivos duales en placas con el hongo y el patógeno. Se determinó que el porcentaje de inhibición del crecimiento radial (PICR) promedio obtenido a los ocho días de exposición (53,66%) no presentaba diferencias significativas (p=0,19) con el obtenido a los 15 días (54,20%) y, dadas las características de inhibición, se presume que el mecanismo de control presentado por la cepa de Gliocladium sp. utilizada responde a la producción de enzimas, metabolitos y posiblemente una mezcla de compuestos orgánicos volátiles capaces de inhibir el crecimiento y desarrollo de S. cepivorum aun sin que sus hifas entren en contacto.

Abstract:

Wilt disease which is caused by Fusarium oxysporum f. sp. capsici is one of the importantdiseases in chili plants that can reduce growth, fruits yield, quality, and chili production. Thisfungus comes inside the vascular bundle through the root tissue and quickly colonizes in xylemvessels and causing typical wilt symptoms on plants. In line with the development of organicfarming systems, biological control by using biological agents is the prospective method incontrolling diseases on the plant. Gliocladium virens are one of the biological agents that obstruct thespreading of disease. The aim of this study was to determine the effectiveness of Gliocladiumvirens in controlling Fusarium oxysporum f. Sp. Capsici on chili plant. This research usedrandomized block design with two factors: 1 The Time application of Gliocladium virens (W)factor; 2. Dosages of Gliocladium virens (D).

Abstract:

Benzene, toluene, ethylbenzene and xylene (BTEX) are monoaromatic hydrocarbons found frequently in petroleum and its derivatives; and they are among the most important pollutants of soil and groundwater. This study focused on harnessing the enzymatic capabilities of filamentous fungi Gliocladium sp. and Aspergillus terreus, dwelling in a petroleum-contaminated soil to degrade benzene, toluene, ethylbenzene and xylene (BTEX) compounds. The biodegradation experiment was carried out using the fungi individually and in consortium in a batch culture containing mineral salts medium supplemented with 1% v/v BTEX. The experiments were carried out in triplicates at room temperature on a rotary shaker (180rpm) for twenty five days and aliquots were taken on a five day interval to determine the hydrocarbon utilizing fungal (HUF) count and residual BTEX in order to monitor the rate of biodegradation. The hydrocarbon utilizing fungal counts were determined by direct counting using a Neubauer Haemocytometer while, the residual BTEX was determined using absorbance values measured using a spectrophotometer and the corresponding concentrations determined from a standard curve. The highest percentage degradation of BTEX was observed with Aspergillus terreus (89.1%) while, the least was observed with Gliocladium sp. (84.4%). The growth peak was attained on the 15th day in all treatments after which the HUF counts declined. Statistical analysis showed no significant difference (P>0.05) in the mean amounts of BTEX degraded and hydrocarbon-utilizing fungal counts between the treatments. The strains of Gliocladium sp. and Aspergillus terreus used in this study showed high ability for BTEX degradation thus, they are potential candidates for bioremediation of soils contaminated with monoaromatic hydrocarbons. Keywords: Biodegradation, BTEX, Gliocladium sp., Aspergillus terreus, Monoaromatic hydrocarbons

Abstract:

Sheath blight is an important disease in corn. The disease could cause significant yield loss when infection occurs on susceptible varieties. Disease control using the microorganism antagonist is an alternative for disease management. Research was carried out in a laboratory, greenhouse and field from 2010 to 2012. The research objective was to compare several biological agents for controlling sheath blight disease on corn. In vitro laboratory tests identified that out of sixteen isolates of microorganisms, only 3 isolates which had the potency to suppress the pathogen of sheath blight over 50%, namely TT1; TM; and GM. Conidia development among the three isolates of microorganism the highest was by TT1. In the greenhouse, three isolates of microorganisms showed potential of decreasing sheath blight disease up to 70%. The Gliocladium isolates decreases the disease by 53%. Research results from the field indicated the antagonist had decreased sheath blight disease by 67%. Isolates of Trichoderma and Gliocladium fungus could reduce the yield loss by 23% by suppressing the infection of sheath blight disease.

Abstract:

Abstract Fusarium wilt (Fusarium oxysporum f.sp. cepae) is the most important soil-borne disease in garlic. This pathogen is a weak parasite so that it can be controlled through healthy plant cultivation approaches such as the use of organic compost fertilizer and soil microbes as biological control agents. Gliocladium sp. is an antagonist fungus that can be used as a soil borne disease control agent. This study aims to evaluate the effectiveness of compost plus Gliocladium to control garlic root rot in endemic land. The experiment was carried out in Tawangmangu Karanganyar at 1000 meters asl. The experiment consisted of 5 treatments arranged by completely randomized design with three replications. The main variables are disease incidence of fusarium wilt and control efficacy. The other variables observed were the fresh and dry weight of the biomass and the yield in the form of the weight of garlic bulbs per plant. Data processing carried out was analysis of variance and DMRT at 5% level. The results showed that compost plus Gliocladium produced higher effectiveness than compost alone or Gliocladium alone. The effectiveness of compost plus Gliocladium was more effective in suppressing fusarium wilt compared to farmers using fungicides and artificial chemical fertilizers.

Abstract:

Lili merupakan tanaman hias penting dan bernilai ekonomi tinggi. Budidaya lili di Indonesia menghadapi kendala utama yaitu penyakit layu Fusarium. Aplikasi bahan kimia sintetik untuk mengendalikan penyakit ini berdampak negatif terhadap kerusakan lingkungan. Aplikasi organisme antagonis dan kultivar resisten merupakan alternatif pengendalian penyakit ramah lingkungan, berdampak positif terhadap kelestariannya, dan meningkatkan produktivitas lili. Penelitian bertujuan untuk mendapatkan informasi mikrobe antagonis, mikrobe nonpatogenik, dan klon lili yang dapat menekan penyakit layu Fusarium. Penelitian dilakukan di Laboratorium Biokontrol dan Rumah Sere, Balai Penelitian Tanaman Hias pada bulan Januari sampai dengan Desember 2007. Tata letak percobaan disusun berdasarkan rancangan acak kelompok pola faktorial denga tiga ulangan. Faktor pertama ialah klon lili yang terdiri dari klon No.1, No 2, No.3 (tahan), dan No.4 (rentan). Faktor kedua ialah perlakuan mikrobe antagonis (1) Gliocladium sp. 107 spora/ml, (2). Trichoderma sp. 107 sel/ml, (3) Fusarium a virulen 107 spora/ml dan, (4) kontrol (tanpa mikrobe antagonis). Hasil percobaan menunjukkan bahwa penggunaan mikrobe antagonis Gliocladium sp. dan klon resisten paling efektif mengendalikan penyakit busuk umbi Fusarium pada lili. Hal ini dibuktikan dari persentase tanaman layu pada perlakuan aplikasi mikrobe dan penggunaan tanaman resistant dibandingkan dengan tanpa perlakuan. Penanaman tanaman resisten diikuti dengan aplikasi Gliocladium paling efektif menekan layu Fusarium dibanding perlakuan lainnya. Lilium is one of the most important and the heigest economic value of cut flower in Indonesia. Cultivation of Lilium faces major constrain, that is wilt disease caused by Fusarium. Application of synthetic chemicals to control the diseases is not recommended, because its impact is dangerous for environment and human life. Therefore other control measures that are move environmentally friendly and more effective/efficient have to applied. The use of antagonistic microbes and resistance varieties are the most promising control measures to be recommended in the field. The study was aimed to find out of antagonist and nonpathogenic microbes and plant resistant that were effective to control Fusarium bulb rot on lili. The experiment was conducted at Laboratory and Glasshouse of Indonesian Ornamental Crops Research Institute (1,100 m asl.) on January to December 2007. Factorial experiment was arranged in a randomized block design with three replications. The first factor was Lilium clones i.e. No.1, No. 2, No. 3 (resistant), and No. 4 (susceptible clone as control). The second factor was antagonism microbes i.e. (1) Gliocladium sp. 107 spora/ml, (2). 107 Trichoderma sp. cel/ml, (3) Fusarium nonpathogenic 107 spora/ml, and (4) control (tap water without antagonist microbe). The results indicated that the use of Gliocladium sp. and resistant clone of Lilium i.e. clone No.3 was effective to control Fusarium bulb rot of Lilium. This proven from lower percentage of disease occurance on the treatment of antagonistics microbes and resistance varieties compared both to those of without treatment (control). The use of resistance plant followed by application of Gliocladium was known to be most effective to control fusarial wilt disease compared to the other treatment combinations.

Abstract:

An indirect immunofluorescence staining procedure was developed for detection of Brunchorstiapinea conidia, using antiserum to conidia and a commercially prepared fluorescein isothiocyanate protein A conjugate. The procedure detected B. pinea conidia from culture, pycnidia, and spore-trap collections. Although cross reactivity occurred with spores of Fusarium spp., Sirococcus sp., Phialophora sp., Gliocladium sp., Verticillium sp., and Gelatinosporium sp., these spores were easily distinguished from those of B. pinea by size, shape, septation, and degree of fluorescence. Fluorescent B. pinea like conidia were collected in spore traps located within and outside the New York State quarantine region. However, the identity of B. pinea like conidia could not be corroborated by other methods.

Abstract:

Penyakit antraknosa pada buah cabai menyebabkan kualitas hasil menurun dan kehilangan hasil yang tinggi. Penyakit ini disebabkan oleh jamur Colletotrichum sp. Pada umumnya, antraknosa pada cabai dikendalikan dengan aplikasi fungisida kimia sintetis pada seluruh permukaan buah. Hal ini sangat berbahaya bila dilakukan menjelang panen karena buah cabai juga dikonsumsi segar. Agens pengendali hayati merupakan alternatif pengendalian Colletotrichum sp. pada buah cabai. Penelitian bertujuan untuk memperoleh isolat agens pengendali hayati yang dapat menghambat perkecambahan spora Colletotrichum sp. penyebab penyakit antraknosa pada buah cabai besar keriting. Penelitian diawali dengan isolasi Colletotrichum sp. dari cabai rawit, besar, dan merah keriting. Isolasi menghasilkan dua buah isolat dari cabai merah besar, 5 isolat diisolasi dari cabai merah keriting, dan 7 isolat dari cabai rawit. Uji virulensi dilakukan untuk memperoleh isolat yang paling virulen terhadap cabai merah keriting. Isolat BA asal cabai besar diketahui memiliki virulensi paling tinggi dibandingkan yang lainnya. Tujuh Trichoderma, 1 Gliocladium, dan 2 APH yang belum diidentifikasi digunakan biakan dalam media cair. Suspensi APH digunakan untuk mengendalikan penyakit antraknosa pada buah cabai merah keriting. Penambahan suspensi LPT2 menyebabkan persentase perkecambahan paling sedikit.

La necesidad de contar con organismos nativos con potencial para el control biológico de plagas para el nogal pecanero, motivaron el registro de la micobiota y búsqueda de entomopatógenos en larvas del gusano barrenador del ruezno (GBR) Cydia caryana. Para ello, en el año 2013, en una huerta de nogal en La Laguna México, se recolectaron y procesaron 5 000 rueznos para extraer larvas de GBR, que fueron incubadas en cámara húmeda o suelo. De larvas obtenidas antes del 12 de septiembre y colocadas en suelo se recobró 9% de Fusarium spp. + Gliocladium spp., en contraste, ambos hongos aparecieron 40% en larvas obtenidas después de esa fecha. En larvas obtenidas en diciembre y se colocaron en cámara húmeda, Fusarium + Gliocladium spp. aparecieron 80%. Únicamente fue evidentemente a Metarhizium anisopliae como entomopatógenos de 5% de larvas del GBR colocadas en suelo después del 12 de septiembre, éste hongo también fue entomopatógenos del ácaro rojo gigante Trombidium sp., pulgón negro del nogal Melanocallis caryaefoliae, Garrapata Rhipicephalus sanguineus, y hormiga roja Solenopsis sp. Larvas de GBR pueden usarse como trampa para recobrar Metarhizium y probablemente otros hongos entomopatógenos en suelo de huertas de nogal pecanero.

Abstract:

The demand for rice as an important food crop in Indonesia is still constrained by the attack of blast disease caused by Pyricularia grisea. Controlling using synthetic chemical pesticides has a negative impact on the environment so that the use of biological agents is an alternative option. This study aims to determine the effectiveness of several biological agents against the pathogen P. grisea that causes blast disease in rice plants in vitro. The study used a completely randomized design (CRD) with 6 levels of treatment and was repeated 3 times using the dooble culture method. The results of the study showed that the inhibition of P. grisea was the highest in the treatment of P. grisea × Trichoderma sp. and P. grisea × Gliocladium sp. namely 67.04% and 51.85% compared to other treatments. The P. polymyxa and P. fluorescence treatments showed low inhibition, namely 23.70% and 28.89%. Biological agents Trichoderma sp. and Gliocladium sp. able to inhibit the growth of the fungus P. grisea. Each biological agent has a different percentage of inhibition in that caused by the inhibitory mechanism of the biological agent.

Abstract:

Microbial isolates from conifer foliage and strawberry were evaluated for biocontrol of Botrytiscinerea Pers.:Fr. in container-grown seedlings of black spruce (Piceamariana (Mill.) B.S.P.). In growth room assays, seedlings were environmentally predisposed to the pathogen and coinoculated with the isolates and B. cinerea. Sporulation incidence of the pathogen was later estimated on needle segments that were cut from the seedlings and incubated on paraquat–chloramphenicol agar medium. The isolates suppressed sporulation by 0–100%. Those of Alternaria, Cladosporium, Epicoccum, yeasts, and bacteria were of low to moderate effectiveness, but those of Gliocladium, Myrothecium, Trichoderma, and Trichothecium were moderately to highly suppressive. In two greenhouse tests, spore suspensions of Gliocladium roseum Link:Bainier and of Myrotheciumverrucaria (Alb. & Schw.) Ditm. ex Stendel. (applied three times) at 2- to 3-week intervals suppressed incidence of B. cinerea by 50–69% and 42–60%, respectively, and were at least as effective as recommended fungicide treatments. Two or three additional applications of the antagonists did not further suppress the pathogen. Isolates of Fusarium sp. and Penicillium sp. were generally ineffective in the greenhouse tests. The four fungi ranked similarly in biocontrol effectiveness in the growth room and greenhouse. It is concluded that the growth room assay provided a strong indication of biocontrol performance in the greenhouse and that G. roseum and M. verrucaria have potential for managing B. cinerea in black spruce in greenhouses.

Abstract:

ABSTRACT The lipases have ability to catalyze diverse reactions and are important in different biotechnological applications. The aim of this work was to isolate and characterize microorganisms that produce lipases, from different food industry effluents localized in Pelotas, RS/Brazil. Bacteria were identified using Gram stain and biochemical tests (Vitek 2(r)). Fungi were identified according to macro and micromorphology characteristics. The extracellular lipase production was evaluated using the Rhodamine B test and the enzymatic activity by titration. Twenty-one bacteria were isolated and identified as Klebsiella pneumoniae ssp. pneumoniae, Serratia marcescens, Enterobacter aerogenes, Raoultella ornithinolytica and Raoultella planticola. Were characterized isolated filamentous fungi by the following genera: Alternaria sp., Fusarium sp., Geotrichum sp., Gliocladium sp., Mucor sp., Paecilomyces sp. and Trichoderma sp. Extracellular lipase production was observed in 71.43% of the bacteria and 57.14% of the fungi. The bacterium that presented better promising enzymatic activity was E. aerogenes (1.54 U/ml) however between fungi there was not significant difference between the four isolates. This study indicated that microorganisms lipase producers are present in the industrial effluents, as well as these enzymes have potential of biodegradation of lipid compounds.

Abstract:

Abstract The aim of this study was the evaluation of activities of versatile peroxidase (VP) in cultures of Clonostachys sp. (Gliocladium sp.) strains during biotransformation of 0.2% alkali lignin (AL). The principal component analysis (PCA) method was applied to determine the main factors and correlation between biotransformation of 0.2% AL, activity of VPs, pH value, and Clonostachys sp. strains. The biotransformation of 0.2% AL in cultures of microscopic fungi included decolorization (medium lightening) and colorization (darkening of the medium). The versatile peroxidase synthesized by the microscopic fungi tested showed activity for oxidation of Mn(II) and guaiacol, but the activity for oxidation of guaiacol in the presence of Mn(II) was significantly higher. The PCA analysis indicated a strong correlation between biotransformation of 0.2% AL and pH and between oxidation of Mn(II), guaiacol without and in the presence of Mn(II) ions, strains, and pH.

Abstract:

Penyakit jamur akar putih (JAP) yang disebabkan oleh Rigidoporus microporus merupakan penyakit penting pada tanaman karet. Pengendalian penyakit JAP umumnya menggunakan fungisida sintetik yang berdampak buruk terhadap lingkungan dan berbiaya mahal. Salah satu cara pengendalian penyakit tular tanah yang lebih murah dan efisien adalah pemanfaatan mikroorganisme antagonis. Penelitian ini bertujuan untuk menguji antagonisme jamur rizosfer tanaman karet (JRK) terhadap R. microporus. Penelitian dilaksanakan dari November 2021 hingga Februari 2022 menggunakan metode survei di Perkebunan Karet Rakyat (PKR) Sakambangan, Kabupaten Garut, Jawa Barat serta metode eksperimental di Laboratorium Fitopatologi, Fakultas Pertanian, Universitas Padjadjaran. Rancangan Acak Lengkap digunakan untuk dua uji antagonisme yaitu dual culture (in vitro) berupa perlakuan 17 isolat JRK dan kontrol R. microporus serta uji potongan akar (in planta) berupa perlakuan 8 isolat JRK dan dua kontrol dengan tiga kali ulangan. Dari hasil penelitian diperoleh 17 isolat jamur termasuk genus Trichoderma, Aspergillus, Penicillium, Gliocladium, Paecilomyces, Acremonium dan Cladosporium, serta empat isolat tidak teridentifikasi. Semua isolat menghambat pertumbuhan R. microporus pada uji in vitro dan kolonisasi pada uji in planta dengan penghambatan tertinggi masing-masing 86,07% dan 85,33%. Trichoderma sp., Aspergillus sp. dan Penicillium sp. merupakan jamur antagonis potensial untuk mengendalikan R. microporus asal PKR Sakambangan.ABSTRACTWhite root rot disease (WRRD) incited by Rigidoporus microporus is an important disease in rubber plants. WRRD is commonly controlled using synthetic fungicide, nevertheless it is expensive and harmful to environment. One way to control soil-borne diseases that is considered cheaper, efficient and safer is by using antagonistic microorganisms. This study aimed to examine the antagonism of rubber plant rhizosphere fungi (RRF) against R. microporus. The research was carried out from November 2021 to February 2022. Research used survey method at a rubber plantation in Sakambangan, Garut Regency, West Java, and experimental method at the Phytopathology Laboratory, Faculty of Agriculture, Universitas Padjadjaran. A Completely Randomized Design was used for the two antagonism tests, namely dual culture (in vitro) of 17 RRF isolates and R. microporus as control treatment while a rubber root piece test (in planta) was used for testing 8 RRF isolates and two control treatments with three replications. The results derived 17 fungal isolates in the genera of Trichoderma, Aspergillus, Penicillium, Gliocladium, Paecilomyces, Acremonium, Cladosporium, and four unidentified. All isolates inhibited the growth (86.07%) and colonization (85.33%) of R. microporus. Trichoderma sp., Aspergillus sp. and Penicillium sp. are potential antagonists against R. microporus of Sakambangan rubber plantation origin.

Abstract:

Dothistroma needle blight (DNB), caused by Dothistroma septosporum and Dothistroma pini, is the most important forest disease of pine in many countries. This disease has recently emerged in Ukraine as a major threat to mostly Pinus nigra subsp. pallasiana and less to Scots pine. There is increasing evidence that some fungal and bacterial isolates can reduce the growth and pathogenicity of fungal plant pathogens. In this research, infected needles were collected from 30-year-old Crimean pine (P. nigra subsp. pallasiana) in four locations in Southern Ukraine. In total, 244 of endophytic fungi were recovered from needles of Crimean pine during summer sampling of the host’s microbiome in Ukraine in 2012-2014. Dothistroma spp. were detected using fungal isolation and species-specific priming PCR techniques. Among all endophytes, eight fungal species were selected based on the commonness of their occurrence in the foliage of the host and their antagonistic activity. All selected species were tested for their antifungal activity against Dothistroma needle blight. Good antifungal activity against Dothistroma pini was achieved with the Trichoderma sp. and Gliocladium rosea, indicating their good potential possibility in preventing the Dothistroma needle blight on young pines. Moreover, the significant reduction in numbers of conidia and spore germination was found on needles treated with Trichoderma sp. and Gliocladium rosea, compared to conidia numbers following treatment with other fungi. Thus, the use of an effective biological control agent against Dothistroma could be of value in forest nurseries, where it is essential to reduce losses to D. pini infection prior to transferring pines to field sites for planting out.

Abstract:

Potential disease control methods were evaluated against root and stem rot of cucumber (Cucumis sativus) caused by Fusarium oxysporum f. sp. radicis-cucumerinum. Crab/shrimp shell chitin; three composted media; the biological control agents Pseudomonas chlororaphis strain 63-28, Trichoderma harzianum (RootShield Drench), Streptomyces griseoviridis (Mycostop), Gliocladium catenulatum (Prestop WP, Prestop Mix), and Trichoderma (Gliocladium) virens (SoilGard); and the fungicides thiram or benomyl were added at seeding time followed by inoculation with the pathogen. The addition of chitin (4%, vol/vol) to a peat-based medium significantly (P ≤ 0.05) enhanced seedling growth, increased soil pH, and reduced F. oxysporum f. sp. radicis-cucumerinum populations, but the severity of disease was increased. The addition of composted media (greenhouse compost, windrow composted dairy solids, and vermi-composted dairy solids) to the seeding cavity in a rock wool block medium, followed 48 h later by inoculation with F. oxysporum f. sp. radicis-cucumerinum, reduced seedling mortality when measured after 37 days. Greenhouse compost was significantly (P ≤ 0.05) more suppressive than the other two composts, and the suppression was partially eliminated by sterilization of the compost. The biological control agent G. catenulatum (formulated as Prestop WP and Prestop Mix) significantly reduced seedling mortality when it was applied at seeding 24 h prior to inoculation with the pathogen in the rock wool block medium. None of the other biological control agents reduced disease incidence when compared with control plants under these experimental conditions. Pseudomonas chlororaphis and the fungicide thiram both significantly reduced plant mortality at 17 and 24°C when pathogen-infested seed was treated, or when bacteria-treated and fungicide-treated seed were planted into pathogen-infested peat medium at 24°C. Under semicommercial propagation conditions, treatments consisting of Prestop WP, RootShield Drench, My-costop, and windrow composted dairy solids reduced the severity of disease caused by F. oxysporum f. sp. radicis-cucumerinum in two out of three trials. The efficacy of the biological control agents was affected by seasonal differences in growing conditions, which affected the incidence and severity of the disease. The results from this study indicate that several different approaches can be used at seeding to control Fusarium root and stem rot on greenhouse cucumber.
