Applying Aquatic Herbicides: Yourself or Pay Someone?

In Ohio, a pond owner has the option to apply algaecides and herbicides to their pond themselves or to hire a licensed applicator.  In most other states, a licensed applicator must be hired for aquatic vegetation treatments.  A professional licensed applicator should be contacted if:

·         The pond owner does not feel comfortable handling chemicals.

o   A licensed applicator knows how to safely handle chemicals and must renew their license every 3 years in Ohio.

·         The pond owner needs to be able to properly identify aquatic plants and algae because herbicides and algaecides are very species specific and selective.

o   A licensed applicator is trained in species identification and can ensure that the correct product is used, in the appropriate amounts.

·         Pond owners usually under-estimate the volume of their pond which leads to incorrect surface acre measurements and incorrect product usage.

o   A licensed applicator is able to accurately measure the pond’s volume and calculate the proper amount of product to be used.

So, ask yourself these questions:

·         Am I willing to take the time to read product labels, making sure to pay close attention to warnings, safety instructions, and restrictions?

·         Am I able to correctly identify the plants causing the problem?

·         Can I accurately calculate the amount of product required to do the job?

·         Do I have the proper application and safety equipment to apply the herbicide?

·         Do I really feel comfortable handling chemicals?

If the answer is “no” to any of these questions, licensed applicators should be contacted.  AQUA DOC will send a licensed applicator to your home or business to assess your lake or ponds needs to properly determine the best maintenance program.
