Pond was totally covered with Duckweed. After one application, duckweed that was treated was gone after about 2 weeks.
Great product! Will buy it again.

I have used this product for years. It keeps my pond weeds under control and if used properly does not harm fish or wildlife.

My pond had an over abundant growth of curly pond weed. After two treatments with Weedtrine D, the pond is clear!
