“…Several species of Botryosphaeriaceae are known to dieback and branch cankers in Citrus spp. worldwide [ 14 , 20 , 22 , 23 , 66 , 67 , 68 , 69 , 70 ]. Dothiorella viticola has been previously reported to cause gummosis in citrus in California [ 20 ] and Tunisia [ 71 ].…”

“…Species of Botryosphaeriaceae have a cosmopolitan distribution and have been associated with numerous plant species worldwide [ 16 , 17 , 18 ]. Many species of the genera Lasiodiplodia [ 19 , 20 , 21 , 22 , 23 ], Diplodia , Dothiorella, Neofusicoccum [ 20 ], and Neoscytalidium [ 14 , 20 ] have been previously reported to affect citrus trees. Togniniaceae (Togniniales), with the well-known asexual morph genus Phaeoacremonium , is another family of fungi traditionally associated with dieback, canker, and yellowing of various fruit, forest, and ornamental trees, worldwide [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ].…”

Citrus trees with cankers and dieback symptoms were observed in Bushehr (Bushehr province, Iran). Isolations were made from diseased cankers and branches. Recovered fungal isolates were identified using cultural and morphological characteristics, as well as comparisons of DNA sequence data of the nuclear ribosomal DNA-internal transcribed spacer region, translation elongation factor 1α, β-tubulin, and actin gene regions. Dothiorella viticola, Lasiodiplodia theobromae, Neoscytalidium hyalinum, Phaeoacremonium (P.) parasiticum, P. italicum, P. iranianum, P. rubrigenum, P. minimum, P. croatiense, P. fraxinopensylvanicum, Phaeoacremonium sp., Cadophora luteo-olivacea, Biscogniauxia (B.) mediterranea, Colletotrichum gloeosporioides, C. boninense, Peyronellaea (Pa.) pinodella, Stilbocrea (S.) walteri, and several isolates of Phoma, Pestalotiopsis, and Fusarium species were obtained from diseased trees. The pathogenicity tests were conducted by artificial inoculation of excised shoots of healthy acid lime trees (Citrus aurantifolia) under controlled conditions. Lasiodiplodia theobromae was the most virulent and caused the longest lesions within 40 days of inoculation. According to literature reviews, this is the first report of L. theobromae and N. hyalinum on citrus in Iran. Additionally, we report several Phaeoacremonium species, S. walteri, Pa. pinodella and C. luteo-olivacea on citrus trees for the first time in the world.

Thailand is known to be the largest producer of kaffir lime leaf products in the global market. In 2021, leaf blight was found on kaffir lime plants (Citrus hystrix DC.) in Lamphun Province of northern Thailand. This disease has been associated with significant economic losses. However, there have been no prior reports of leaf blight on kaffir lime plants in Thailand or anywhere else in the world. In this study, causal fungi were isolated from lesions of kaffir lime plants and a total of three fungal isolates were obtained. All causal fungi were identified as Lasiodiplodia chinensis based on morphological characteristics and the phylogenetic analysis of combined sequences of the internal transcribed spacer (ITS) of ribosomal DNA, the translation elongation factor 1-alpha (tef-1), β-tubulin (tub), and RNA polymerase II subunit (rbp2) genes. Pathogenicity tests were conducted and the results revealed that all isolated fungi caused symptoms of leaf blight on inoculated leaves. This outcome was similar to symptoms that naturally occur and have been observed in the field. This is the first report on kaffir lime leaf blight caused by L. chinensis. Our study will provide information of high value for the development of effective strategies for the monitoring and prevention of this disease.

“…Gejala mati ranting dan busuk buah pada jeruk oleh L. theobromae dilaporkan di Meksiko (Picos-Muñoz et al 2015) dan gejala penurunan keragaan tumbuh di Pakistan (Fateh et al 2016). Penyakit gumosis pertama kali yang disebabkan oleh L. theobromae dilaporkan di Chili pada jeruk limau (Citrus aurantifolia) oleh Guajardo et al (2018) dan menjadi masalah utama pada buah lepas panen di Banglades (Hasan et al 2020). Spesies lain yang berasosiasi dengan penyakit bot gumosis pada jeruk di California diidentifikasi sebagai L. parva (Adesemoye et al 2014).…”

Kabupaten Bangli, Bali merupakan salah satu sentra produksi jeruk di Indonesia. Kendala pada produksi jeruk di antaranya ialah penyakit busuk pangkal batang yang disebabkan oleh Lasiodiplodia theobromae. Tujuan penelitian ini menentukan faktor budi daya, letak geografis, dan curah hujan yang berkaitan dengan penyakit ini. Pengamatan kondisi penyakit dan wawancara mengenai teknik budi daya ditanyakan kepada 50 petani pemilik. Keterkaitan antara teknik budi daya dan keparahan penyakit dianalisa dari data korespondensi yang dipetakan dengan grafik biplot dan analisis kontingensi dengan uji khi kuadrat. Berdasarkan pada analisis korespondensi dan kontingensi terdapat 4 faktor cara budi daya dan 1 faktor tanaman yang berkaitan nyata terhadap keparahan busuk batang jeruk. Faktor tersebut ialah frekuensi penyiangan secara mekanis, umur tanaman, populasi tanaman per hektar, aplikasi herbisida, dan dosis pupuk nitrogen.
