Abstract
Abstract The experiment was conducted at the TAMU Agricultural Research and Extension Center at Beaumont and was designed as a RCB with 4 treatments and 4 replications. Plots were 20 ft × 8 ft and broadcast planted at 70 lb seed/acre on 1 May. Seed was untreated (no fungicide) except that which was treated with 3 oz of NTN 33893/100 lb seed by Mobay employee Dr. Lyndon Almand. The seed-bed was cloddy and dry at planting after which plots were culti-packed to cover seed. Urea was applied at 63, 51, and 51 lb N/acre at planting, immediately before the permanent flood, and at panicle differentiation, respectively. Thiobencarb was applied pre-emergence at 4 lb (AI)/acre, and propanil and bentazon were applied at 4 and 0.75 lb (AI)/acre, respectively, 3 d before initiation of the permanent flood which was applied 24 d after rice emergence. From planting to permanent flood, plots were flush irrigated as needed. Bensulfuron methyl was applied at 1.0 oz (AI)/acre 6 d after initiation of the permanent flood. Furadan 3G was applied with a hand shaker at the times designated in the table. Five, 4 inch diam X 4 inch deep soil cores (each containing at least 1 plant) per plot were removed, washed and inspected for immature RWW 19 d after initiation of the permanent flood. At maturity, the middle 2.5 ft × 20 ft of each plot was harvested with a small combine. Yields were adjusted to 12% moisture. Where appropriate, data were transformed (Vx + 0.5) and analyzed by ANOVA.
