Broadleaf Weed Control - Triad Select™ 3-Way Herbicide

Allyn always recommends that when you are first starting out with spraying weeds in your lawn (post emergent weed control) you try a store bought product first and learn with that. This is because these products are more “watered down” and give you some more fudge factor while you are learning.

The interesting thing about this product here, Triad Select, is that it is the same active ingredients as many of these store bought products, but they are in much higher formulations. In fact, this product is very similar to ones the pros use on their routes everyday.

It contains 3 very effective active ingredients: Dicamba, 2,4D and MCPA. When you see these products in the store bought stuff, the concentrations are between 1-3% for each. But in Triad Select the concentrations are:

2,4-D. . . . .30.89%

MCPA. . . . 8.23%

Dicamba. . 2.77%


All that to say: if you are looking to try something that is “stronger” but don’t want to spend alot, this is an excellent choice. It is primarily recommended for cool season lawns (kentucky bluegrass, turf type tall fescue and ryegrass) but can also be used on Zoysia and bermuda.

The max rate is 1.5 oz of concentrate per 1,000 sq ft. This formulation is a liquid concentrate that you mix in water in a pump sprayer or battery sprayer and apply as a liquid. It is not to be applied via a hose end sprayer - only via backpack, pump sprayer or larger tank sprayer equipment.

We have a 1 quart bottle (32 oz) that will cover 21,000 sq ft if mixed at the max rate of 1.5 oz/gallon/1000. If you do the math here, you will see this is actually cheaper to apply than the store bought stuff!

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.

Recommended: Do not apply if temperatures are over 90F. If temps are that high, apply in the evening when they dip below 90F and elect to spot spray instead of blanket spraying.

This product can be used on all cool season grasses, bermuda and zoysia as well as bahia grass. It should not be used on centipede or St Augustine.

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.
