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.

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.
