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.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days.
Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!
