Interpretive Summary:

Technical Abstract: The development of a healthy root system early in the season can provide a foundation on which the overall production system is built allowing the plant the opportunity to reach the genetic potential for maturity & yield. In these studies the objectives were to determine the influence of early seedling disease control strategies on stand establishment, crop development & yields & to assess the utility of the COTMAN expert system i determining the influence of these strategies on plant development. Test plots were established at 7 locations (NC, GA, MS, LA, CA, & 2 in TX) across the cotton belt that represent the major cotton production areas of the US. Each test consisted of the 5 core treatments: Nonfungicide-treated seed with an in-furrow application of DiSyston 15G at 6.7 lbs/a, & seed commercially treated with fungicides & an in-furrow application with 1 of the following chemicals: DiSyston 15G at 6.7lb/n, Temik 15G at 7.0 lb/a, DiSyston 15G at 6.7 lb/a plus Terraelor Super X 18.8G at 7.0 lb/a. At the end of the season, seed cotton was harvested. The COTMAN expert system was utilized throughout the season to determine the influence of the carious treatments on fruit retention & development. The results from the 1999 season indicated that a reduction population density between the black seed control compared to the other treatments. These differences did not generally translate into differences in yield since observations that critical population densities were not reached coupled with the indeterminate growth habit of cotton, resulted in sufficient compensation to minimize differences. Preliminary analysis of information from the COTMAN system indicates differences in maturity between locations.
