Knockout Aquatic Herbicide (5L)
Knockout Aquatic Herbicide is a low-toxicity glyphosate approved for use in and around waterways. The chemical is mixed with a surfactant (wetting agent) that makes it kinder on aquatic environments than regular glyphosate (NOT approved for aquatic environments). This product has better results on taller plants and grasses like cumbungi and spike rush.
Note: this product is NOT appropriate for submerged weeds because the chemical becomes inert when it comes into contact with water. If you are using it on floating weeds/leaves, wait for a calm day when the wind and wave action is low. We don't recommend using Knockout on azolla or duck weed, try the Aquatic Weed Killer instead.
Knockout Aquatic Herbicide is suitable for the following aquatic weeds:
- All grasses
- Alligator weed
- Cumbungi
- Phragmites
- Common reed
- Rushes
- Sedges
- Water hyacinth
- Water couch
- Water lettuce
- Waterlily

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
