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.

Definitely Worth It
Quick and easy process. Coffee maker died and I had the insurance. Refunded and only ended up paying the price of insurance. Would do it again!

Claim was easy, speedy, and Amazon gift card was applied almost immediately.
I had to make a claim for a Ninja blender that was emitting an odor of burning or melting wires. I called a service representative thinking I might encounter a problem and was surprised. The agent was helpful and made the entire process so easy I applaud her! The Amazon gift card was posted to my account almost immediately after UPS picked the product up. I have decided that for products with a large number of parts and electronics that can fail I will purchase Asurion protection.

Asurion "Assures" nothing!
Asurion has terrible Customer Support. All machine based. They give you no phone # for human interaction. Their online Support process is very close-ended. It is a checklist designed to frustrate purchasers whose issue lies outside only the very issue.
My issue: I bought "Cuisinart TOB-40FR Custom Classic Toaster Oven Broiler, Silver (Renewed)" on May 26, 2024. It stated it had a 90 day warranty. So I bought an Asurion Protection Plan also to cover it for 3 years. The toaster started flaking off metal finish inside the oven over the cooking area. I tried to file a claim with Asurion and they told me the Manufacturers warranty was still in effect and I should contact Cuisinart. This despite the oven was sold with a Amazon Renewed verbiage stating a 90 day warranty.
And they have nothing on their "Machine Checklist" to cover this eventuality. And I would assume I am not the only one who takes the "Renewed" route and backs it up with a "Protection Plan".
They will frustrate you no end. I suspect, like many insurances, they seek to deny, deny, deny, in hopes the purchaser will give up.
