Burmese teak is a light-loving tree species. Its native habitat has an average annual temperature of 20℃-27℃, with a minimum temperature of 2℃, and annual rainfall of 1100-3800 mm. It has distinct wet and dry seasons and is a strongly photophilic species. It can grow in red and lateritic soils developed from sandstone, shale, and granite. It prefers deep, moist, fertile, and well-drained soil. Teak diseases include sclerotinia root rot, bacterial wilt, and rust.
Root Rot: Due to root decay, the ability of Burmese teak to absorb water and nutrients gradually weakens, eventually leading to the death of the entire plant. The main symptom is yellowing and wilting of the entire leaf. It generally occurs from late March to early April, with the peak incidence in May.
Bacterial Wilt: Caused by *Ralstonia solanacearum*, a bacterium belonging to the Solanaceae family. Initially, the plant shows no abnormalities in the above-ground parts, but suddenly loses vitality during the day, and the entire above-ground part withers. The plant recovers somewhat on cloudy days and in the early morning and evening, appearing healthy; however, it soon withers, exhibiting symptoms of wilting. This process progresses very rapidly.
Rust: A type of plant disease caused by rust fungi. It affects the leaves, stems, and fruits of plants. Rust fungi generally cause only localized infection. Affected areas may develop small pustules of different colors or pustules, cup-shaped, or hairy growths due to spore accumulation. Some rust fungi can also cause tumors, rough bark, bushy branches, and crooked branches on the stems, or cause leaf drop, scorched tips, and poor growth. In severe cases, the spore masses densely cluster, and the plant rapidly dies due to the large amount of water lost through evaporation.
