Description Seeding diseases account for major losses in stands of cotton (Gossypium hirsutum L.). The use of fungicide treatments may enhance seedling survival. Our objectivs were to evaluate the effect of several fungicide treatments on emergence, stand establishment and yield of cotton, and to compare the effectiveness of seed treatment versus in-furrow soil applications. During 1987, four fungicide seed treatments (Captan, Captan + Apron, Captan + Apron + Vitavax, and Nuflow ND + Apron) and three in-furrow fungicide applications (two rates of Ridomil PC and one rate of Terrachlor Super X) were evaluated. Treated seed had higher (P < 0.05) emergence rates (97% to 194%) than the control. There were no differences (P > 0.05) among in-furrow applications. Stand establishment for the treated seed was higher (140-330%) than the control as was the in-furrow treatments of Ridomil PC (high rate) and Terrachlor Super X (150% for each). The seed and in-furrow treatments produced 37-84% higher lint yields than the control. The highest emergence and stand establishment resulted from seeds treated with Captan + Apron, and Nuflow ND + Apron. The highest lint yield resulted from seeds treated with Captan + Apron, Captan + Apron +Vitavax, and Nuflow ND + Apron. During 1988, the seed treatments, Captan, Captan + Apron, and Captan + Apron + Demosan were evaluated. Multiple seed treatments (Captan + Apron, and Captan + Apron + Demosan) generally produced 42 to 43% higher seedling emergence and 36% higher stand establishment compared to the control; however, no yield differences among the treatments were observed. Our results show that for improving emergence, establishment and yield of cotton, multiple fungicide seed treatments are generally superior to single treatments and to in-furrow treatments.
