Abstract
Abstract Essex variety soybean was planted May 8 at the West Tennessee Experiment Station, Jackson, TN. Bedford variety (resistant to races 1, 3, and 4 of the soybean cyst nematode Heteroderaglycines) was planted as a nematode resistant check. Subplots were two 40 inch rows by 30 ft long replicated 4 times in a split plot design. The soil type was a Memphis silt loam (0-M.:1.1456; pH:6.1). Soil moisture was good with 1.12 inches of rain during the week following planting. Granular insecticides were applied in-furrow or in an incorporated 8 inch band in front of the planter sword. Furadan 4F (2.0 lb ai/acre) was applied in an 8 inch band behind the press wheel at 8.9 gal of spray per acre. Lexone herbicide was applied pre-emergence to specified main plots in 20 gal of spray per acre (8003 tips, 30 psi, and 4 mph). Nematode populations were below damaging levels. Beetle counts were made 3 weeks after planting by counting the number of dead bean leaf beetle (BLB) in 3 ft of row in each row. Sub-plots were harvested Oct 7 and yields expressed as bu/acre at 13% moisture.
