Katana® - The others just don’t cut it
Take out glyphosate resistant ryegrass for longer
Maintaining a clear area beneath the vines can take up a lot of time, labour, and fuel. But there’s no way round it as weeds compete with grapevines for resources and can impact crop health and productivity throughout the season. One weed in particular is giving growers increasing headaches: Glyphosate resistant ryegrass. Katana offers a powerful solution that not only controls glyphosate resistant ryegrass, but also a broad range of weeds long-term.
What is Katana?
Katana (flazasulfuron) is a new, residual herbicide that provides undervine weed control for up to 5 months. Already a go-to in European vineyards, Katana tackles weeds long before they can turn into a problem.
How does Katana work?
Rapidly absorbed by roots and shoots, Katana inhibits Acetolactate Synthase (ALS), a key enzyme of base amino acid production. As a result, downstream synthesis of vital plant proteins is stopped, and the plant dies. When used on germinating seedlings, Katana acts in the soil to prevent further plant growth and emergence. When applied to already present plants (2-4 leaf), growth stops immediately, followed by leaf discolouration and then dieback over a 3-6 week period.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them
Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard
White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it.
Orange is easy to see in the grass at day
They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too
The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

Cheap but expected, worked as intended, none of them broke.
Size: 1000 Teaspoons
Seems to be cheap quality but what else can you expect for the price? I needed something cheap that would work for cold foods, and these delivered. They lasted me forever and I didn’t have any break, I just didn’t trust them with super hot foods. I will buy again in a heartbeat though because for everything else they work great. They are small spoons that don’t hold much, bend easily, are really lightweight and I wish they came in portions or wraps because after opening they sat there collecting dust through the hole in the box and so I had to transfer them to a closed container for sanitary purposes. Again though, I didn’t really expect anything else, so I’m happy regardless.
