Abstract

Field research was conducted in 1973, 1974, 1977, and 1978 to compare water-culture practices and rates of molinate ( S -ethyl hexahydro-1 H -azepine-1-carbothioate) for control of “strawhull” red rice ( Oryza sativa L.) in water-seeded rice (O. sativa L.). Water-culture treatments (continuously drained, alternately drained and flooded, or continuously flooded during the first 28 days after seeding) alone, or preplant, soil-incorporated treatments of molinate (3.4, 4.5, and 6.7 kg/ha) alone did not control red rice. Treatments of preplant-incorporated molinate at 4.5 and 6.7 kg/ha in a continuously flooded culture or 6.7 kg/ha in an alternately drained-flooded culture controlled 87 to 93% of the red rice and permitted production of satisfactory yields of high quality rice grain.
