Abstract
A fate assessment of the herbicide endothall (AQUATHOL®) was conducted on Pat Mayse Lake, Texas, during the summer of 1983 in conjunction with an aquatic plant management program forMyriophyllum spicatum L. (Eurasian watermilfoil). Aqueous endothall concentrations were below the minimum detectable level of 0.002 mg/L within 72 hr after treatment and below the minimum detectable level in sediments (0.01 mg/kg) within 96 hr. Both dilution and biodegradation probably contributed significantly to rapid transport and degradation. Endothall was not detected in fish tissue on any sampling day. Concentrations considerably less than the label-recommended dose rate for partial surface treatment were measured, indicating that AQUATHOL® may be used in sensitive aquatic environments with minimal nontarget effects.
