Chemical control of rice blast in Korea

, : Chemical control of rice blast in Korea. International Symposium on pesticide use in developing countries present and future: 113-123

Cultivation of high-yielding varieties, including indica-japonica rice hybrids, and improved production technology have increased the rice yield potential and changed the pattern of Pyricularia oryzae incidence. Annual yield losses to blast in S. Korea were estimated at 8.4% for the last 5 yr, assuming no chemical control was initiated. Normally such control provides an annual increase of 6.3% or 0.27 t/ha in yield.
