ECOS Preventative Aquatic Weed Control

Program sizes available for ponds 1/8 acre to 1 acre.

ECOS - Early Control Optimized Sonar Performance

ECOS Preventive Aquatic Weed Control is a Sonar powered prescription designed to optimize performance and provide season-long, broad spectrum weed control in ponds and small lakes. This pre-emergence use of Sonar optimizes efficacy by treating plants as they emerge from the hydro-soil and have low energy reserves: thus making them susceptible at lower use rates and providing more rapid control. Timing of this pre-emergence use is based upon regional location and local growing zone and growing degree day influence on aquatic plant growth.
