A field research test was conducted to examine the effects of Terrazole 4E at various rates combined with Terraclor 2E for the control of Pythium spp. cotton seedling disease. Treatments consisted of Terrazole 4E at 3, 4, 5 and 6 oz/acre each combined with 64oz/acre of Terraclor 2E and an untreated control. Plots consisted of four rows and two of the four rows were inoculated with Pythium spp. infested oat seed. From 14 through 42 days after planting, all treated plots contained a significantly greater plant stand compared to the inoculated control. There were no significant differences in plant stands between the rates of Terrazole 4E. At harvest, significantly more nodes per plant recorded in the Terrazole 4E (5 oz/acre) compared to the inoculated control. However, there were no differences in plant height between any of the treatments. Seed cotton yield ranged from 2479.7 to 2116.3 lb/acre in the inoculated Terrazole 4E (5 oz/acre) and the inoculated control respectively.
