Durian (Durio zibethinus) is known as the king of fruit in Southeast Asia (Bampenrat et al., 2020), and is one of the most economically important export fruits in Thailand (Charoensumran et al., 2021). However, a major problem affecting durian plantations in Thailand is stem rot disease. Symptoms of the infected trees are bark and trunk canker, twig blight, yellow leaves, and wilting.
This report provides evidenced that F. solani and L. pseudotheobromae are the fungal pathogens causing stem rot disease on durian trees. Previous reports described these fungi causing stem rot in hackberry and mango (Khanzada et al., 2004; Liang et al., 2020). To date, Phytophthora sp. has been attributed as the cause of stem rot disease on durian trees in Thailand. Misidentification of the stem rot fungal pathogens could result in the use of inappropriate methods to control the disease.
