Two cotton seedling disease fungicide seed treatment tests were conducted at Northeast Louisiana University. In test 1, treatments consisted of WE 120C, WE 120C + NuFlow M, WE 120C + NuFlow M + Apron TL, Captan 4000 + NuFlow M + Apron TL, NuFlow ND + NuFlow M + Apron TL, Maxim 3FS + NuFlow M + Apron TL, RTU Baytan-Thiram + Apron TL and an untreated control. In test 2, treatments consisted of Delta Coat AD, Delta Coat AD + Delta Gib, Ridomil PC 11G, Terraclor Super X 12.5 G, and an untreated control. All treatments were applied to Stoneville 474 seed by the Wilbur Ellis Corporation. Plots of test 1 were inoculated with Rhizoctonia solani infested oat seed in the seed furrow at planting while test 2 was not inoculated. In test 1, the high rates of WE 120C, WE120C + NuFlow M, WE 120C + NuFlow M +Apron TL, Captan 40000 + NuFlow M + Apron TL produced significantly greater cotton stands at 14 and 28 days after planting, than the control. Plant stand at 42 days after planting ranged from 77 to 38 plants per forty foot of row in the high rate of WE 120C and the untreated control respectively. Seed cotton yields ranged from 3234 to 2021 lb of seed cotton per acre for the Maxim 3FS + NuFlow M + Apron TL and untreated control respectively. In test 2, no significant differences in cotton seedling stand were observed at 7, 14, 21, and 28 days after planting. However, by 42 days the Terraclor Super X treatment had a greater stand than Ridomil PC and the untreated control. Plant stand at 42 days ranged from 153 to 138 plants per forty foot of row in the Terraclor Super X and the control treatments respectively. Seed cotton yields ranged from 2763 to 2422 lb/a of seed cotton in the Delta Coat AD + Delta Gib and untreated control respectively. The net value increase in cotton yield over the control ranged from $27.86 to $145.86 per acre for Terraclor Super X and Ridomil PC respectively.
