Triad Select™ 3-Way Herbicide utilizes a combination of three selective herbicides to control a wide variety of hard-to-kill broadleaf weeds. This is an excellent all-around 3-way herbicide that is a “bump up” from store-bought herbicides.

  • Active ingredients are 2,4-D (30.89%), MCPA ( 8.23%), Dicamba (2.77%)
  • Great for treating dandelion, clover, chickweed, wild onion and broadleaf plantain
  • Safe for use on Kentucky Bluegrass, Turf Type Tall Fescue (all fescues), Ryegrass, Bermuda, and Zoysia.
  • DO NOT USE on Centipede, St. Augustine, or Bahia grasses
  • Available in multiple sizes *

Product Description:
Triad Select is a selective, post-emergent herbicide that contains the same active ingredients, (Dicamba, 2,4D, and MCPA), as many store-bought products. However, you will find that Triad Select contains much higher herbicide formulations. In fact, this product is very similar to the ones the pros use on their routes every day.

Here are the common weeds that Triad controls:
Dandelion, Lespedeza, Poison Oak, Wild Carrot, Black Medic, Dockweed, Mallow, Purslane Wild Garlic, Buckhorn, Ground Ivy, Morningglory, Ragweed, Wild Lettuce, Burdock, Peppergrass, Sheep Sorrel, Wild Onion, Chicory, Henbit, Pigweed, Shepherd’s Purse, Yarrow, Chickweed, Knotweed, Plantain, Speedwell, Clover, Lambsquarters, Poison Ivy, Spurge

Note: it is not the best weed killer for ground ivy or creeping charlie. It will stunt it so if you have it use it, but triclopyr is better.

It is not required, but if you want to, you can also add in a non-ionic surfactant to increase the “stickiness” of the Triad weed control.

Been a K&N customer for over 20 years.
I use K&N on all vehicles that I have owned. It has always given extra MPGs and extra HPs. Always easy to install, easy to clean and maintain. if you keep your vehicle as long as I do (my last two vehicles, a 2001 Toyota Sienna lasted 18 years, and 2000 honda civic LX lasted 17 years), this filter pays for itself and more! definitely worth the price. I bought one now for my new Honda Civic EX hatchback which I will also drive until it breaks which could be 2 decades from now - imagine how much I will save on regular air filter purchases and extra mpgs. very well worth the price!

Best Air Filter EVER
I have used these in my cars for years. They improve turbo lag significantly, increase air flow, and just work. What I like best about these, beside the protection they offer the air intake system, is that they truly are a life long product. My last car had one in it for 13 years. With a cleaning every 25K miles as outlines by KN the air filter just continued to work and work. I recently purchased one for my new Honda CR-V and had it installed at the dealership at 500 miles when I was getting an oil change to flush out the build lube. The mechanic who did the work left me a note that said "great filter, I love these"

Worth it! Love these filters.
I love K & N air filters and always install them in my cars. This eliminated my cars Turbo lag in my 2019 Honda Civic Ex which has a 1.5L Turbo. Acceleration has improved and makes the car louder (I also have dual exhaust) I love how you don't have to change or clean it for 50,000 miles!! I know it's expensive but will last forever! Only issue was it was very difficult to install and a pain but this is more Hondas fault as I could not fully remove the plastic case where this filter goes under the hood even with tools.
