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%, 25%,50% and 75% 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% significantly showed high level of dried out disease. |
