The shoot of Thyrsostachys siamensis Gamble is usually damaged by bamboo shoot borer, bamboo aphid and dried out disease. This experiment was carried out to test that thinning would effect the incidence of pests and diseases. This research was done in 6 years old plantation, located in Thong Pha Poom district, Kanchanaburi province. Four levels of thinning were used as 0 percent, 25 percent, 50 percent and 75 percent of the total number of culms within each clump. The result is non significance among treatment on shoot production and the damaged by shoot borer. However, thinning at 75 percent significantly showed high level of dried out disease.
