“…Lasiodiplodia theobromae, a member of Botryosphaeriaceae, is a wellknown pathogenic fungus and soil-borne saprophyte that infects a wide range of host plants, both pre-and post-harvest (Domasch et al, 1980;Lawrence et al, 2016) tropical and subtropical regions (Ismail et al, 2012), and more than 500 host plants such as almonds, blueberries, cocoa, grapevines, mangos, olives, bananas, anthurium, cotton, apple and peanut have been reported (Alves et al, 2008;Daengsuwan et al, 2019;Galvez et al, 2016;Hong et al, 2012;Ismail et al, 2012;Kuswinanti et al, 2019;Nam et al, 2016;Naz et al, 2021;Salaemae et al, 2022;Shakirah et al, 2022). The fungus has been associated with several disease symptoms on import commercial crops, including dieback, fruit rot, stem end rot, pod rot, panicle brown rot, decline, twig and stem blight and stem canker (Amrutha & Vijayaraghavan, 2020; Daengsuwan et al, 2019;Galvez et al, 2016;Hong et al, 2012;Mehmood et al, 2021;Nam et al, 2016;Naz et al, 2021;Shakirah et al, 2022;Yildiz et al, 2014).…”

“…Dieback disease, which is caused by the fungus Lasiodiplodia theobromae , is one of the most globally destructive diseases to strawberry, and is found in countries such as Turkey, Korea, Pakistan and United States (Mehmood et al, 2021; Nam et al, 2016; Oliveira et al, 2019; Yildiz et al, 2014). Typical symptoms of the dieback disease include wilting and necrotic discoloration of roots and crown region, with the collapse of the entire plant (Mehmood et al, 2021). Previously, this disease had not been found in Thailand.…”

In Thailand, strawberry production is confined mainly to Chiang Mai and Chiang Rai Provinces, located in the mountainous northern region, where the cool climate from December to March permits production (Pipattanawong, 2015). Strawberry plants are highly susceptible to high temperatures due to the reduction of strawberry flower formation and fruit quality (Klamkowski & Treder, 2008). Moreover, higher temperatures generate a higher demand for water, creating water stress in plants during dry seasons (Moretti et al., 2010). Therefore, strawberry is often harvested in winter and spring, but not in summer (Yamasaki, 2013). The greenhouse cultivation of strawberry, which provides protection from rain, pathogens and insects, and which ensures an optimal temperature environment, can be carried out throughout the year (Shigeoki et al., 2017).To produce strawberry all year round, greenhouse cultivation with an evaporative cooling system is often used for strawberry cultivation in Thailand (Pipattanawong, 2015). Like all commercially cultivated fruits, strawberries face a number of threats. Common diseases include leaf scorch, leaf spot, leaf blight, powdery mildew and anthracnose (Pipattanawong, 2015).However, strawberry plants are especially susceptible to fungal pathogens which can affect almost all parts of strawberry (Maas, 2012), and the occurrence of several fungi that infect strawberry crowns and roots has given rise to concerns that production

“…The identification was based on the morphological characteristics and molecular similarity was based on multiple DNA loci (ITS, tef1-α, and tub2). Fungi of the genus Lasiodiplodia belong to the family Botryosphaeriaceae and are commonly found in tropical and subtropical areas [29], causing several diseases in many plant species [35][36][37]. In Thailand, Lasiodiplodia species have been associated with various diseases, for instance, canker in rubber trees [38], spadix rot of Anthurium andraeanum [39], and fruit rot in longan [33].…”

“…Lasiodiplodia species do not form appressoria or other structures to penetrate plant tissues, but are pathogenic to host plants. Several publications have revealed that fungi in Botryophaeriaceae can invade host plants through endophytic ability, injuries, soil contamination, or insect infestation [5,[35][36][37][38][39][40][41][42][43][44][45][46]. To date, the infection mechanism of Lasiodiplodia species and how they become pathogenic is still unclear.…”

The rubber tree is an important economic tree in Thailand. Recently, the cultivation of rubber trees in Thailand has suffered from a novel leaf fall disease with diverse symptoms, including leaf spot and leaf blight, resulting in severe leaf defoliation. Fungi from the Lasiodiplodia genus, which causes leaf disease in rubber trees, have not been reported in Thailand. Our research aimed to identify Lasiodiplodia associated with leaf blight disease in Thailand by examining morphological characteristics and completing a multi-gene sequence analysis and pathogenicity test to fulfill Koch’s postulates. The internal transcribed spacer regions, translation elongation factor 1-α, and β tubulin 2 were sequenced for the multi-gene sequence analysis. In total, we recovered 14 isolates with 6 of those isolates. Of the six pathogenetic isolates, LST001, LST002, LYT003, LSrt001, and LSrt002 were determined to be Lasiodiplodia chonburiensis, and isolate LYL005 was determined to be L. theobromae. To the best of our knowledge, this is the first report of L. chonburiensis and L. theobromae being associated with leaf blight disease in rubber trees in Thailand or elsewhere.
