摘要

K. S. McLean, and W. S. Gazaway. Auburn University, Auburn, AL Cotton fungicide tests were planted in north, central and southeast Alabama. The tests were conducted in fields with a history of cotton seedling disease. Fungicides were applied as a seed treatment or as an in-furrow spray or granular applications at planting. All in-furrow fungicide sprays were applied with flat tip 8002E nozzles calibrated to deliver 20 GPA at 30 PSI. All in-furrow granular applications were applied with chemical applicator boxes attached to the planter. Plots consisted of 2 rows, 25 to 30 ft long with a 36 to 38 in. wide row spacing and were arranged in a randomized complete block design with six replications. Blocks were separated by a 20 ft alley. Each plot was infested with millet seed inoculated with Pythium spp. and Rhizoctonia solani. The nemattcide Temik 15G (5lb/A) was applied in-furrow at planting. All plots were maintained throughout the season with standard herbicide, insecticide and fertility production practices as recommended by the Alabama Cooperative Extension Service. Stand counts, skip index and vigor ratings were recorded at 2, 4 and 6 weeks after planting to determine the percent seedling loss, stand density and seedling vigor due to cotton seedling disease. Plots were harvested by one row harvesters.
