This cuts out the light, killing any submerged aquatic plants and also disguises where water starts and ends, being potentially dangerous to wildlife, pets and children.Blagdon's Duckweed Buster prevents the duckweed from taking up the nutrients it needs to grow, causing it to die back. Like all vegetative treatments, Blagdon recommend that as much duckweed as possible is removed manually prior to treatment, as this will avoid having a pond full of dead rotting duckweed. ## Features - Kills your Duckweed efficiently Highly effective Simple to use Step by step instructions on use Dosage chamber for easy application ## Images ![Blagdon 500ml Duckweed Buster - Image 1](https://m.media-amazon.com/images/I/61HLjTU1+QL.jpg) ![Blagdon 500ml Duckweed Buster - Image 2](https://m.media-amazon.com/images/I/61S0tVpPRlL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐ Does not work *by O***Y on Reviewed in the United Kingdom on July 3, 2021* I really did follow the instructions, but this did not work in my pond. It was hard for me to remove all the duckweed from my pond, as it hides amongst the iris roots and lilies, but I certainly did my best before each treatment. I followed the instructions and dosed the pond each week until the bottle ran out, but the duckweed was coming back as fast as I could catch it and treat it. You wonder how long you should be wasting your money for. The blanket weed treatment I used earlier in the year did work (it dissolved it), although it is back now and needs another bottle thrown at it, but this had no effect whatsoever on the duckweed! ### ⭐⭐⭐ It does work, it just takes time! *by F***Y on Reviewed in the United Kingdom on July 3, 2019* I followed the instructions to the letter, but can't remove all the duckweed as it's stuck among the irises. After three applications, nothing seemed to be happening, except a load of blanket weed grew. So I had to buy some blanket weed treatment, which worked really well. Now the duckweed is dispersed over the pond with lots of space between, so I can' fish it out any more. It has cost me a fortune. However 4 months down the line, in August, the duckweed has not grown back and is virtually gone. I have got two more bottles of treatment to use if it starts to grow again. ### ⭐ Limited effect *by C***K on Reviewed in the United Kingdom on October 21, 2021* After applying the initial dose the duckweed did seem to be less. I applied the second dose but it has come back with a vengeance. In the end it did not help removing duckweed from the pond permanently. ## Frequently Bought Together - Blagdon Pond Duckweed Buster, Controls Duckweed, Safe and Natural, 500ml, Treats 4,546 Litres of Pond Water - Blagdon Pond Sludge Buster, Digests Harmful Organic Waste, Introduces Good Bacteria, Keeps Pond Clean, 4 x 9g Sachets, Each Sachet Treats 2,273 Litres - Blagdon Clear Pond Water Treatment, 1 Litre, Clears Dirty Green or Brown Cloudy Water Quickly, Natural, Wildlife Safe, Harmless to Fish and Filter Bacteria, 1L, Treats 20,000 Litres of Water --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/35958167-blagdon-500ml-duckweed-buster](https://www.desertcart.co.uk/products/35958167-blagdon-500ml-duckweed-buster) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
