My lawn is infested with Canadian Thistle, but I'm fighting back with Tordon RTU. It works like a charm. Just drizzle some Tordon on the weed, and it, and most of the root, dies in a day or two (faster acting in direct sunlight).

I have ordered this product numerous times over the last few years. Performance as advertised. Easy to use. Instructions large
enough to read. Shipped in a timely manor.
Thanks for a great product.

Good price for this product.

Ordering was quick and easy. Delivery was prompt. When Keystone has a product I need they will surely be my supplier.

I use Topsin in conjunction with some other fungicides as part of a rotation to prevent possible immunity buildup on my wine grapes. Topsin is an important part of my arsenal. A user needs to exercise caution if they are using small amounts from the water soluble bags. The bags will easily disintegrate, as designed for large scale applications, if any water should be accidently spilled on them.

Worked well to eliminate filamentous algae in our pomd.
