| Judul Artikel | Inventarisasi dan Identifikasi Penyakit Akibat Jamur pada Tanaman Jambu Air Varietas Citra di Desa Kajongan dan Cipawon, Kabupaten Purbalingga |
| Abstrak (Bhs. Indonesia) | Tujuan dari penelitian adalah untuk inventarisasi dan identifikasi penyakit, serta mengetahui intensitas penyakit tersebut pada tanaman jambu air Citra di Desa Kajongan dan Cipawon, Kabupaten Purbalingga, Jawa Tengah. Penelitian dilaksanakan melalui survei pengamatan gejala penyakit di lapang, dilanjutkan identifikasi patogen di Laboratorium Perlindungan Tanaman, Fakultas Pertanian, Universitas Jenderal Soedirman. Penelitian dilaksanakan dari bulan Oktober 2020 sampai Maret 2021. Survei dilakukan untuk mengamati gejala penyakit di lapangan, penyebab penyakit, dan kondisi umum di wilayah pengamatan. Metode pengambilan sampel dilakukan secara purposive sampling. Sampel yang diperoleh diidentifikasi menurut pustaka. Variabel yang diamati adalah kondisi pertanaman, suhu dan kelembaban udara, gejala penyakit, kejadian penyakit, intensitas penyakit, dan morfologi patogen. Hasil penelitian menunjukkan bahwa penyakit yang ada di lokasi penelitian adalah embun jelaga yang disebabkan oleh Capnodium sp. dan antraknosa yang disebabkan oleh Colletotrichum sp. Penyakit embun jelaga memiliki gejala berupa lapisan hitam pada permukaan daun. Identifikasi mikroskopis patogen penyebab embun jelaga menunjukkan adanya konidiomata yang khas dan hifa bersepta. Identifikasi mikroskopis patogen penyebab antraknosa ditunjukkan dengan adanya konidia berbentuk silinder, hifa bersepta dan bercabang, serta aservulus. Intensitas penyakit cendawan jelaga di dua lokasi pengamatan tergolong sedang, sedangkan intensitas penyakit antraknosa di dua lokasi pengamatan sangat rendah. |
| Abtrak (Bhs. Inggris) | The aim for this research is to inventory and identify of Citra water guava disease and also their disease intensity at Kajongan and Cipawon village, Purbalingga regency. The research was conducted through an observation survey to the disease symptoms in the field, followed by identification of pathogens in the Plant Protection Laboratory, Faculty of Agriculture, Jenderal Soedirman University. The study was conducted from October 2020 to March 2021. The survey was conducted to observe the symptoms of the disease in the field, the causes of the disease, and the general condition in the observation area. The sampling method was carried out by purposive sampling. The samples obtained were identified according to the references. The variables observed were planting conditions, air temperature and humidity, disease symptoms, pathogen morphology, disease incidence, and disease intensity. The results showed that the disease at the study site was sooty mold caused by Capnodium sp. and anthracnose caused by Colletotrichum sp. The sooty mold disease has symptoms as a black coating on the leaf surface. Microscopic identification of the pathogen causes sooty mold show as specific conidiomata and septate hyphae. Symptoms of anthracnose were showed by sunken dark brown spots on the fruit. Microscopic identification of the pathogens that causes anthracnose was showed by cylindrical conidia, septate and branched hyphae, and the presence of acervules. The intensity of sooty mold disease in the two observation fields was moderate, while the intensity of anthracnose in the two observation areas was very low. |
