Abstract
Field experiments were conducted to investigate methods of controlling red rice ( Oryza sativa L. ♯ ORYSA) in drill-seeded rice ( O. sativa ). Treatments included the rice cultivar ‘Mars', coated with calcium peroxide (CaO 2 ) at 40% (w/w) and a crop protectant, R-33865 ( O,O -diethyl- O -phenyl phosphorothioate) at 0.5 and 1% (v/w). Molinate ( S -ethyl hexahydro-1 H -azepine-1-carbothioate) at 6.7 kg ai/ha was applied preplant incorporated (ppi). The land was flooded (2.5 to 5 cm deep) after seeding with rice (100 kg/ha, 2.5 cm deep), and the water was maintained throughout the growing season. CaO 2 , with or without molinate, increased rice grain yield 50% and increased rice culm density fivefold above untreated rice. Molinate applied ppi controlled 96% of the red rice. Rice seed coated with only CaO 2 or with CaO 2 plus R-33865 at 0.5%, each combined with ppi molinate, produced 5690 and 6030 kg/ha of grain, respectively. These high yields were associated with red rice control by molinate and good stands of rice provided by O 2 supplied by CaO 2 . R-33865 applied to rice seed at 1% (v/w) injured rice by reducing rice culm densities 41%, compared with rice without protectant.
