Field Evaluations of HPPD Tolerant Cotton in Western Texas

Field trials were conducted at 4 locations in western Texas to evaluate HPPD cotton tolerance to isoxaflutole applied preemergence and early postemergence.  Treatment "systems" also included the use of glufosinate and glyphosate.  Cotton phytotoxicity was evaluated throughout the growing season and yield and quality determined at the end of the growing season.
