Why

granular aquatic herbicide for bottom-growing weeds is the ideal approach when you need a treatment that sinks to the target zone and supports flexible water-use practices. Harpoon Granular Aquatic Herbicide is designed to work from the bottom up, helping manage bottom-growing, copper-sensitive aquatic plant species in ponds, lakes, and other managed water bodies—especially where you can’t pause irrigation, swimming, fishing, or livestock watering.

Why choose a sinking granular treatment

Unlike products that primarily treat the surface, a granular aquatic herbicide for bottom-growing weeds delivers the active ingredient down through the water column, positioning it where many nuisance species start and spread. This makes it a strong fit for spot treatments as well as broader applications when infestations are established throughout the waterbody.

Target weeds & use cases

  • Helps control common submerged and floating nuisance plants such as hydrilla, naiads, coontail, elodea, and water hyacinth.
  • In waters with low alkalinity (hardness), it may also control Eurasian watermilfoil, sago, curly leaf, and select weeds in the pondweed family (performance can vary by site conditions).
  • Useful for projects where treated water needs to remain usable immediately for irrigation, animal consumption, swimming, or fishing.

Application notes

  • Apply as a spot treatment for localized growth or scale up for larger treatment zones.
  • Label rate range: 40 to 240 pounds per acre-foot.
  • Active ingredient: 9.87% Copper Ethylenediamine Complex.
  • Always read and follow label directions, including any site-specific restrictions and best practices.

Please note shipping limitations may apply by location. If you’re planning a program-based approach, a granular aquatic herbicide for bottom-growing weeds can be paired with monitoring and follow-up treatments to help maintain long-term control and reduce regrowth pressure.

FAQ

Q: Can treated water be used right away? A: The product is intended for sites where water use cannot be restricted; follow the label for your specific use and location.

Q: What determines which weeds are controlled? A: Species present, growth stage, water chemistry (including alkalinity/hardness), and coverage all influence results—use the label and local guidance for best outcomes.

Eaten by my Thighs
Color: 04-multicolour (4-pack), Size: X-Large
I wanted to love them. Sadly they have let me down. Pros: natural breathable fabric , super soft and comfortable, cotton panty gussets for feminine health and panty liners will stick!! Yay:). And the colors! They are great! But here’s the Con. And it’s the con of all cons. THEY RIDE UP!! Eaten by my thighs. I’m 5’6” and in the general area of 175. I fluctuate depending on how many times I visit the bakery! :) I don’t have a thigh gap but it is not a super tight thigh squeeze. I seldom have thigh climb but these do. I tried two different sizes to see if that made a difference. Nope. I was miserable at a recent theme park in these. I was wearing long heavy dresses and it was quite awkward to yank these legs down non stop. They feel amazing and they have all the requirements 1. Soft 2. Comfortable and stretches with you 3. Breathable with nice thin fabric. Not bulky 4. Natural fibers 5. Great colors If you are a person that is not blessed with Thunder Thighs, please order these. They are great! I wear them at home and to locations that I will not be doing a lot of walking at. I have washed them so many times and they look like new still.

Best Boxer Briefs for Women!
Color: 09-multicolour (4-pack), Size: Large
I rarely give 5⭐️’s but these deserve it! Hands down, the most comfortable material, stitching, waistband, moisture wicking and overall comfort. They sit right beneath my bellybutton, they wash and dry well and they’re sturdy. I have tried 3 styles and these are the best.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.

Well made, light fabric. Waist doesn't roll.
These bamboo underwear really do keep you cool. They fit true to size, and wear easily. the wide elastic waist band doesn't roll on me. They are comfortable to wear, washed and dried easily. The material has some stretch to it, but not a lot. Well made, no stray strings. Perfect fit for me. Just what I was looking for.

Good quality, smooth feel
I got these briefs so recently that have washed just one pair so far. First off, these are very comfortable, the material is soft & bordering silky, good quality sewing. Wash well and minimal if any shrinkage. They do come a bit wrinkled from the dryer but hey, these are underwear and will go on smoothly. If it were a t-shirt, I would look sloppy. I feel the sizing is accurate. No rolling and these don't announce themselves under clothing. Planning on getting more of these boxers and replacing my old panties.
