This technical note describes the results of a field demonstration to examine the effectiveness of combining endothall applied as Aquatholregistered K with other aquatic herbicides for control of hydrilla. Concentrations and combinations were based on previous greenhouse trials conducted at the Lewisville Aquatic Ecosystem Research Facility LAERF in Lewisville, Texas, using Aquatholregistered K, Rewardregistered diquat, Hydrotholregistered 191 endothall and Cutrineregistered-Plus chelated copper. The use of herbicide combinations is a widespread and documented practice in the agricultural community but is a less defined practice in aquatic vegetation management. Herbicide combinations may offer significant advantages over the use of a single material, including improved and extended weed control, reduced herbicide rates and application costs, shorter contact times for improved results in flowing water, less stringent use restrictions, improved selectivity.
