The identification of soil fungi isolated from Rhizosphere in different varieties of jali plants (Coix lacryma-jobi) in Loa Kulu, Kutai Kartanegara, Indonesia. Asian J Agric 2: 44-47. The rhizosphere effect indicated the development of active microbial population around the roots driving from the loss of organic materials. This research was intended to identify rhizosphere microbes by identifying the potential microbes four different varieties of jali (Coix lacryma-jobi L.) in Loh Sumber, Loa Kulu, Kutai Kartanegara, Indonesia, i.e., jelai beras, jelai ketan, ketan lekat, and jelai kaltara. The soil samples were collected and isolated in the area of jali plantation in Loa Kulu, Kutai Kartanegara at 45 days after planting. As many as 16 isolated samples were used, collected from four different variety of jali and 4 times of replication. The result showed that a variety of microbes at Rhizosphere could be classified as Trichoderma sp. Aspergillus sp., Pythium sp., Fusarium sp., Cunninghamelal sp., and Penicillium sp..

Penelitian ini bertujuan untuk menginventarisasi jamur yang terdapat pada beberapa varietas benih kedelai [ Glycine max (L.) Merril ] yang berada di sekitar Bandar Lampung. Penelitian ini dilakukan di Laboratorium Penyakit Tanaman, UniversitasLampung dari Mei 2013 sampai dengan Agustus 2013. Penelitian ini menggunakan kedelai varieta Burangrang, Kaba, Argomulyo, Tanggamus dan Grobogan. Benih-benih tersebut diinkubasi menggunakan metode blotter test dan agar plate test dengan dua perlakuan, yaitu kontrol (tanpa NaOCl) dan dengan menggunakan NaOCl. Jamur-jamur yang tumbuh dari benih yang diinkubasi diidentifikasi dengan cara diamati dan difoto, selanjutnya dicocokkan dengan bubu-buku referensi tentang penyakit- penyakit kedelai. Selain itu juga dilakukan penghitungan persentase kemunculan jamur dari benih yang diinkubasi. Hasil yang diperoleh dari penelitian yang dilakukan dengan perlakuan desinfeksi maupun tanpa desinfeksi ditemukan jenis jamur yang berasal dari lapang (Fusarium sp., Cercospora sp., Sclerotium sp., Phomopsis sp., Rhizoctonia sp., dan Colletotrichum sp.) dan jenis jamur yang berasal dari gudang penyimpanan (Trichoderma sp., Aspergillus sp., Penicillium sp., dan Rhizopus sp.). Benih yang diberikan perlakuan desinfeksi dapat mengurangi tumbuhnya jamur yang berasal dari gudang/tempat penyimpanan (kontaminan) tetapi tidak menghilangkan jenis jamur yang menginfeksi di dalam benih (jamur yang berasal dari lapang). Pada varietas Grobogan Rhizoctonia sp. memiliki persentase kemunculan jamur yang lebih tinggi dibandingkan dengan jamur lainnya yaitu sebesar 60,56%. Pada benih dengan perlakuan tanpa desinfeksi persentase kemunculan Aspergillus sp. pada varietas Kaba dan Tanggamus lebih tinggi dibandingkan dengan jamur lainnya sebesar 63,33%. Pada media perlakuan desinfeksi dengan menggunakan media kertas saring persentase kemunculan jamur pada varietas Kaba Cercospora sp. memiliki persentase lebih tinggi dibandingkan dengan jamur lainnya sebesar 30%. Pada media perlakuan tanpa desinfeksidengan menggunakan media kertas saring, Trichoderma sp. pada varietas Kaba memiliki persentase kemunculan jamur lebih tinggi dibandingkan dengan jamur lainnya, dengan persentase kemunculan masing-masing sebesar 77,23%.

The present study provides baseline information on the quantitative and qualitative estimation of aeromycoflora. Burkard personal airsampler and Anderson two stage airsampler were used to detect the quantitative and qualitative estimation of aeromycoflora. 17 non-viable fungal spores were recorded with the aid of Burkard personal airsampler and 12 viable fungal genera were detected using Anderson two stage airsampler. Higher concentration airborne fungi observed in the month of March. Aspergillus sp, Ascospore, Basidiospore, Curvularia sp, Alternaria sp were found to be Nigrospora sp most predominant nonviable fungal genera whereas dominant viable genera were Aspergillus sp, Penicillium sp, Cladosporium sp, Curvularia sp, Trichoderma sp and  Fusarium sp in both the environments. The result of antifungal potential of Clerodendrum infortunatum showed highest efficacy against Aspergillus sp followed by Penicillium sp and Fusarium sp. This present study provided the baseline information about the viable and non-viable concentration in the study sites. Besides the outcomes of this study along with the insightful explanation could aptly provide basis for strategizing effective preventive measures against airborne-fungi. Those are responsible for causing different agricultural crops diseases and human respiratory ailments.

Abstract. Rasyid B, Ala A, Kuswinanti T, Sapareng S. 2020. Exploring functional fungi on organic matter decomposition of oil palm empty bunches as bio-resource in land remediation. Biodiversitas 21: 4247-4252. Organic matter of oil palm by-product has the potential to be applied for land remediation. The objective of this experiment was to explore functional fungi on the decomposition effectivity of oil palm empty bunches. Samples were collected from oil palm plantation fields and oil palm factory. Isolated fungi from decomposed material (trunks and rod) were Penicillium sp., Pleurotus sp., Fusarium sp., Chrysosporium sp., and Aspergillus sp. Fungi in the empty fruit branches were identified as Absidia sp., Tremella sp., and Trichoderma sp., Phytophthora sp., Ulocladium sp., and Chaetomium sp. Within all collected fungal isolates, Pleurotus sp., Trichoderma sp., and Tremella sp. were selected as functional fungi based on the results of the highest lignocellulolytic ability (50-75%). The degradation rate of organic matter of each functional fungi was observed as Trichoderma sp. (24.0%), Tremella sp. (20.0%), and Pleurotus sp. (16.0%). Change of C/N ratio as a result of decomposition showed significant difference compared to control with 22.09 by Trichoderma sp., 24.26 by Pleurotus sp., 26.68 by Tremella sp. and 36.58 in control. This study could be concluded that exploring functional fungi can potentially be applied in the decomposition of oil palm by-product effectively.

O controle das podridões das espigas e grãos de milho é realizado principalmente com a aplicação de fungicidas químicos em todas as regiões produtoras do Rio Grande do Sul. O presente trabalho teve como objetivo avaliar a influência da aplicação foliar de fungicidas na incidência de grãos ardidos e de fungos dos gêneros Penicillium sp., Fusarium sp. e Aspergillus sp. em grãos de milho. O experimento foi conduzido na safra agrícola 2014/15, em Cruz Alta, RS. O delineamento experimental utilizado foi o de blocos casualizados (DBC), com 4 tratamentos (3 com aplicação de fungicidas e 1 testemunha sem aplicação) em 4 repetições. Os tratamentos basearam-se nas aplicações dos fungicidas Piraclostrobina + epoxiconazol (380 mL ha-1), Picoxistrobina + ciproconazole (300 mL ha-1) e Azoxistrobina + benzovindiflupir (150 g ha-1). As variáveis analisadas foram: percentagem de grãos ardidos, massa de mil grãos e rendimento de grãos. Houve efeito da aplicação de fungicidas sobre toas as variáveis avaliadas. Os componentes de produção assim como a incidência de grãos ardidos e de fungos fitopatogênicos, em grãos de milho são influenciados pela aplicação via foliar de fungicidas no estádio fenológico V8 da cultura do milho.

O conhecimento do comportamento natural da nogueira Pecan às principais doenças é de suma importância para o estabelecimento do planejamento da implantação da cultura. O controle fitossanitário e tratos culturais devem ser realizados de modo a não comprometerem a qualidade do produto final, as amêndoas. Foram avaliadas nozes produzidas na safra de 2005 e oriundas de Uraí-PR, pelas cultivares Burkett, Frotscher e Moneymaker, para identificar e quantificar os microrganismos associados à amêndoas e cascas dos frutos, bem como observar diferenças entre organismos colonizadores das cultivares. Os frutos foram avaliados na pós-colheita, aos trinta dias de armazenamento em ambiente, através da metodologia do papel de filtro, sendo submetidos ou não à assepsia superficial. O fungo Cladosporium caryigenum, promotor da rancificação das amêndoas foi observado, em amêndoas e cascas, nas cultivares Burkett, Frotscher e Moneymaker; Fusarium sp., foi encontrado em porcentuais elevados, tanto em amêndoas quanto em cascas das três cultivares estudadas; Cephalothecium roseum, causador do mofo róseo em amêndoas, na cultivar Frotscher. Aspergillus sp. e Penicillium sp., causadores de emboloramento e produtores de aflotoxinas foram observados em porcentuais representativos, em amêndoas da cultivar Frotscher e em amêndoas e cascas das cultivares Frotscher, Burkett e Moneymaker, respectivamente. Os maiores porcentuais de perda do rendimento foram observados na cultivar Burkett, por causa da incidência de Colletotrichum sp., causador da antracnose em amêndoas, que acarreta escurecimento e deterioração do produto final, levando-o ao descarte.
