ASPECTOS ETIOLÓGICOS DA OCORRÊNCIA DA SECA DO CACHO DA BANANEIRA PRATA (Musa sp. AAB) NO ESTADO DE GOIÁS ETHIOLOGICAL ASPECTS OF BANANA BUNCH DRYING OCCURRENCE IN Musa sp. AAB Cv. PRATA IN THE GOIÁS STATE, BRAZIL
Universidade Federal de Goiás, 2007Co-Authors: Lincoln F. Zica, Yvo De Carvalho, Wilma Alves FerrariAbstract:<!-- @page { margin: 2cm } --> <p class="western" align="justify">No presente trabalho procurou-se determinar a causa da “seca do cacho” de banana do cultivar Prata (<em>Musa sp.</em> AAB) e analisar alguns aspectos de sua ocorrência no Estado de Goiás. A doença afeta drasticamente a produção, e ocorre mais severamente durante o período chuvoso (outubro - abril), podendo, em certas regiões, afetar quase todos os cachos. Mediante os resultados obtidos em isolamentos sob condições axênicas e através da aplicação do postulado de Koch, determinou-se que a causa primária da doença á o fungo <em>Gloeosporium musarum Cooke & Massee</em>, atuando sob condições climáticas predisponentes. Foi sugerido que características clonais, condições climáticas e potencial de inóculo disponível sejam os principais fatores envolvidos na distribuição regional da enfermidade.</p> <!-- @page { margin: 2cm } --> <p class="western" align="justify">The purpose of the present study was to determine the cause of the drying of the bunch in the “Prata banana” (Musa sp. AAB) and to analyze some of the aspects of its occurrence in the State of Goiás. The disease drastically affects production, and occurs more severely during the rainy season (October to April) , going so far as to affect almost all of the bunches in certain regions. Based on the results obtained in isolation, under aseptic conditions, and using Koch’s postulate, the primary cause of the disease was determined to be the fungus Gloesporium musarum Cooke & Massee, which acts under predisposing climatic conditions. It was suggested that clonal characteristics, climatic conditions, and the potential of available innoculum were the principal factors involved in the spread of the disease in certain regions.</p>

description of colletotrichum lupini comb nov in modern terms
Mycologia, 2002Co-Authors: Helgard I Nirenberg, Uta Feiler, Gregor HagedornAbstract:Gloeosporium lupini Bondar is transferred to Colletotrichum. The fungus is characterized morphologically and illustrated. The two varieties, Colletotrichum lupini (Bondar) Nirenberg, Feiler & Hagedorn, comb. nov. var. lupini and Colletotrichum lupini var. setosum Nirenberg, Feiler & Hagedorn var. nov. are described. They are compared with additional Colletotrichum species reported from lupins and other hosts by morphological and physiological methods as well as by RAPD-PCR and DNA-sequencing.

Eksplorasi Khamir Pada Tanaman Apel (Malus sylvestris Mill) Dan Uji Potensi Antagonisnya Terhadap Penyakit Busuk Buah Gloeosporium gloeosporioides
2017Co-Authors: Sianipar, Yohanna ElisaAbstract:Gloeosporium gloeosporioides merupakan jamur penyebab penyakit busuk buah pada Apel (Malus sylvestris Mill). G. gloeosporioides menjadi salah satu penyebab semakin menurunnya produksi Apel dari tahun ke tahun. Pengendalian yang selama ini dilakukan adalah dengan menyemprotkan fungisida secara terus menerus. Penggunaan fungisida secara berlebihan menyebabkan berkurangnya mikroorganisme tanah dan kesehatan tanah semakin menurun. Dengan mempertimbangkan hal tersebut, pengendalian menggunakan agens hayati mulai digunakan untuk meminimalisir kerugian dan dampak negative yang disebabkan oleh aplikasi fungisida. Agens hayati yang digunakan dalam penelitian ini adalah khamir dengan tujuan mengetahui dan memperoleh jenis khamir yang terdapat pada bagian tanaman Apel serta mengetahui daya antagonismenya terhadap G. gloeosporioides. Khamir merupakan mikroorganisme uniseluler yang telah banyak dikembangkan sebagai agens hayati pengendali beberapa penyakit pada tanaman. Khamir telah digunakan untuk mengendalikan penyakit antraknosa pada cabai dan stroberi, jamur akar putih pada cengkeh, bercak kuning sigatoka pada pisang, dan penyakit lainnya yang telah diteliti sebelumnya. Kelebihan dari khamir adalah lebih adaptif terhadap permukaan tanaman yang kering dan miskin nutrisi Penelitian dilakukan di Laboratorium Penyakit Tumbuhan Jurusan Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya pada Februari sampai dengan Juli 2017. Eksplorasi khamir berasal dari bagian kulit, daun, dan batang tanaman apel, serta uji antagonis khamir terhadap G. gloeosporioides meggunakan media PDA dan dilakukan pengamatan selama 7 hari setelah inokulasi (HSI) Khamir yang diperoleh dari bagian kulit dan batang sebanyak 6 isolat antara lain Hansenula sp., Candida sp., Cryptococcus sp., Pichia sp. 1, Pichia sp. 2, dan Rhdotorula sp. Pengamatan uji antagonis dilakukan selama 7HSI (hari setelah inokulasi) dan hasil pengamatan menunjukkan bahwa daya hambat tertinggi dihasilkan oleh khamir Hansenula sp. (47,94%) sedangkan daya hambat terendah dihasilkan oleh khamir Rhodotorula sp. (12,41%)

Mahonia aquifolium – a new host of Colletotrichum japonicum comb. nov.
Julius Kühn-Institut, 2012Co-Authors: Bedlan GerhardAbstract:Im Juni 2011 wurde an Mahonia aquifolium ein Blattflecken verursachender Pilz entdeckt, der als Gloeosporium japonicum determiniert wurde. Es handelt sich hiermit um den ersten Nachweis von Gloeosporium japonicum in Europa sowie um eine neue Wirtspflanzenart dieses Pilzes. Aufgrund morphologischer Merkmale wird Gloeosporium japonicum in die Gattung Colletotrichum transferiert. In June 2011 a fungus was detected on Mahonia aquifolium which caused leaf spots. It was determined as Gloeosporium japonicum. This is the first report of Gloeosporium japonicum for Europe and of a new host for this fungus. Based on morphological characters Gloeosporium japonicum has been transferred to the genus Colletotrichum.

Colletotrichum carthami comb. nov. on safflower (Carthamus tinctorius)
Julius Kühn-Institut, 2012Co-Authors: Bedlan GerhardAbstract:Im Juni 2010 wurde erstmals in Österreich der Pilz Colletotrichum carthami comb. nov. (Synonym Gloeosporium carthami (Fukui) Hori et Hemmi (1919)) an Saflor (Carthamus tinctorius) nachgewiesen. Befallene Felder, die besichtigt werden konnten bzw. von denen ein Befall bekannt wurde, wiesen nahezu einen Totalverlust auf. In June 2010 the occurrence of the fungus Colletotrichum carthami comb. nov. (synonym Gloeosporium carthami (Fukui) Hori et Hemmi (1919)) was first reported on safflower (Carthamus tinctorius) for Austria. Infested fields which could be observed and those from these infection has been reported, showed nearly a totally yield loss.
