How To Apply
Mix the amount of Ultra Pondweed Defense® and Treatment Booster™ PLUS (if using) with pond water in a tank sprayer according to label instructions. Use a pressurized pond sprayer to spray the Ultra Pondweed Defense® mixture directly onto to the target weeds. Treat only up to half of the pond's surface and wait 10-14 days before a second treatment. In hot weather or when fish are stressed, treat only 1/4 - 1/3 of the pond's surface at a time. For deeper water, place the sprayer's tip beneath the water's surface. Over time, the weeds will begin to brown and die. Once completely dead, use a rake, like the Pond & Beach Rake, to remove dead weeds to prevent an accumulation of dead plant material and muck.
When To Apply
Ultra Pondweed Defense® has no temperature restriction, but it should only be applied when weeds are actively growing. Use with Treatment Booster™ PLUS for best results.
- Wait 3 days before using treated water for human drinking water.
- Wait 1 day before using treated water for livestock and domestic animal consumption.
- Wait 5 days before using treated water for irrigation.

"New product for us"Cathy and Larry King of Pensacola, FL
A massive thank you for a great product! Wish we had only known of and used this product sooner. My husband and I have been pouring a lot of hard-earned cash into an ever-growing expense treating our 3 acre lake in hopes of controlling the weeds. Over the years we have literally spend thousands of dollars. In the last two months, two treatments that appeared to work at first - but regrowth was to no avail and returned very quickly again. The treatment failed. The weeds did not die. I was sick to think our hard-earned money was literally being poured down the drain. The treatments we have come to depend on were not working. We were becoming very dissatisfied and told that perhaps EVEN MORE EXPENSIVE products may be necessary. Then we decided to "try" your Ultra PondWeed Defense with Treatment Booster PLUS to treat our lilies. We sprayed only one 32 oz of Ultra PondWeed Defense with 8 oz Treatment Booster PLUS and 4 gallons of water onto the lily weeds growing in our 3 acre lake. By the same afternoon we noticed the lilies were already beginning to darken and die! Within 3-4 days all the lilies have died and disappeared! Amazing! The product really works, now we have a solution to our weeds! Thank you for rebuilding our confidence in the treatments for our lake. The results are amazing! No doubt if we have additional concerns or questions we will be your returning customers! Thank you thank you, we can't say it enough! PS I love the ease of measuring found "pre-marked" on the containers! It definitely takes the guess-work out of measuring!View entire review
