During 1993, root and foliar pathogens of seedling cotton were examined from five farms located within a 100 km radius of Lubbock, Texas. The root systems of 14-21 day-old Paymaster HS-26 seedlings were excavated from black seed control plots in an experiment replicated on three farms. Forty root systems from each farm were rated for disease severity on a scale of 1 (healthy) to 5 (totally discolored or necrotic). Isolations were made from the tap roots of 72-96 plants per farm onto three media--water agar amended with 100 µg/ml streptomycin sulfate, P(10)ARP selective for Pythium and Phytophthora spp. (2), or TB-CEN selective for Thielaviopsis basicola (3).
