Abstract
Abstract The experiment was conducted at the TAMU Agricultural Research and Extension Center at Beaumont and used a RCBD with 9 treatments and 4 replications. Plots were 10 ft × 12 rows (7 inches between rows) and drill planted at 100 lb seed/acre on 19 Apr. Rice emerged 2 May. Facet + Basagran were applied 21 May at 0.75 lb formulated material/acre and 0.75 qt/acre, respectively. The permanent flood was applied 7 Jun. Urea was applied at 68, 51, and 51 lb N/acre at the seedling stage, immediately before the permanent flood, and panicle differentiation, respectively. Granular carbofuran was applied with a hand shaker at the time designated in the table. Furadan 4F was applied with a 4-nozzle hand-held spray boom equipped with 800067 tips and 50 mesh screens. Final spray volume was 27.6 gal/acre and times of applications are recorded in the table. Five, 4 inch diam × 4 inch deep soil cores (each containing at least 1 plant) were removed, washed and inspected for immature RWW 22-23 d after initiation of the permanent flood. At maturity all the rice in each plot was harvested with a small combine. Yields were adjusted to 12% moisture. Data were analyzed using ANOVA and means were compared using DMRT where applicable.
