Evaluation of Single and Multiple Fungicide Seed Treatments on the Emergence and Establishment of Texas High Plains Cotton

Norman Hopper, James Supak, and Harold Kaufman


 
ABSTRACT

Studies to determine the effectiveness of single and multiple fungicide seed treatments on cotton seedling emergence, stand establishment and survival, and lint yield were conducted in the field during the 1988 growing season. Growing conditions until mid-July were somewhat cool and moist while the conditions for the remainder of the growing season were warmer and drier. Fall conditions were near ideal with warm and dry conditions and an exceptionally late freeze date.

During the 1988 growing season, the fungicide seed treatments were evaluated using the cultivar Paymaster 145. The study was planted on 17 May at a seeding rate of 26 seeds meter-1 of row in 1.016 meter rows. The experimental area was fertilized with 87 kg ha-1 of nitrogen and 38 kg ha-1 of P2O5. Weeds were controlled by a preplant incorporation of Treflan (1.75 L ha-1) and a preemergence application of Dual(2.0 L ha-1) and Caparol (2.8 L ha-1). In addition, Temik (2.8 kg ha-1) was applied at the time of planting of early season insect control. The plot area received a preplant irrigation plus two seasonal irrigations to supplement the rainfall. A randomized complete block design was used with four blocks.
