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, 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.
SePRO’s ECOS program is simple to implement and will provide excellent control season-long for submersed aquatic weeds. ECOS is guaranteed* by SePRO, providing you a time & frustration-saving solution for submersed weed control.
Step 1: Weed Identification
Do you have any of these submersed weeds in your pond?
Step 2: Measurement
How big is your pond?
Calculate Rectangular Pond Size:Enter Pond Length (ft)
Enter Pond Width (ft):
Enter Pond Depth (ft):
Acres (surface area):
Calculate Circular Pond Size:
Enter Shoreline Length (ft):
Step 3: Timing
What state is your pond in? What time of year is it?
Step 4: Select Your ECOS Program
The next step is simple. If you have a submersed weed on the list and are within your region's start time, select the appropriately sized ECOS program below.
