Abstract

Paddy or Oryza sativa is an important crop in Malaysia after oil palm and rubber. In Malaysia, paddy has two types such as paddy field and upland rice. According to the International Rice Research Institute (IRRI), people around the world need 300 million tonnes of rice for 2020 to fulfill the need of a fast-growing human population because the paddy or rice is a staple food for more than half population in the world.

Brown spot is one of the diseases that affect the quality and quantity of paddy yield. The fungus attacked brown spot disease was Bipolaris oryzae. The objectives are to determine the incident and severity of brown spot as well as the factor integrated the disease. This case study about disease incidence and severity was done at Tanjong Karang, Selangor. In this case, incidence and severity of brown spot disease was observed at three difference fields at Tanjong Karang, Selangor. The method is a pipe 1m x 1m was used to measure and places it randomly on the quadrant at three difference field at Tanjong Karang, Selangor. All data were observed and recorded. The results show that the field A is the highest percentage of disease incidence and severity (69.61 %, 56.00%) and then followed by field B (65.95%, 44.89%) and field C (31.96%, 35.11%). The several factors that possibility infected to incidence and severity brown spot such as soil pH, amount of fertilizer, amount of fungicide, temperature and rainfall.
