Product Overview

Triad Select employs a mixture of three selective yet potent herbicides in order to control a broad variety of broadleaf weeds that are labeled hard-to-kill such as clover, dandelion, and plantain. This has been demonstrated and confirmed through university trials to be an efficient and effective solution that can be administered to both cool and warm season grasses and is labeled for use on sod farms, turf-grass, and other non-crop industrial areas. This formula can be mixed in a tank with liquid iron materials or liquid fertilizers following the label for instructions and compatibility on fertilizer tank mix. It has flexible application rates and may be applied to non-cropland areas' woody brush.

Note: Due to New California State restrictions, this Can Not be Sold in California.

    The stuff works great

    By Tim on 07/13/2017

    By far the best thing I have found to kill clover and crab grass. I've spent way too much time and money trying to get the clover in my yard under control over the last few years. I have yet to find anything at the big box stores that does a good job. I mixed this in my sprayer with a few squirts of dish soap and went to work. The next day you could see the clover already hurting and turning brown. I would highly recommend this if you have clover or other broad leaf problems in your yard.

    Great Product!

    By Lee on 12/03/2018

    Finally! I found a product that kills the weeds in my grass! I have tried 2-4d with little effect, even after several treatments. With Triad, not only does it kill the ones that 2-4d killed, but it also kills the weeds that 2-4d didn't touch. It usually takes two treatments, and you don't see the immediate results, but after a week or so, the plants start to die. Within several weeks, they are gone.

    Weed control

    By Paul on 04/30/2019

    I am using this product at a rate of 1.5oz/gal in a hose end sprayer. It is doing a great job controlling weeds in my lawn without harming the grass.

    this works

    By Robert on 05/11/2018

    bought to fight hennepin which is a purple weed that takes over here in Arkansas in late February. Me and everyone fights it every year. Everyone just calls it purple weed. Talked to a Representative and bought this triad. I've used 2, 4-D and never had good results. This stuff isn't any more than 2, 4-D but has 2 other chemicals. Put it on first of March and it worked. I'll buy this for any 2, 4-D type chemical from now on. I do have one weed left, but don't know what it is. It has a leaf looks like a phyladandrum. I have never seen it before. We will see what happens after Bermuda gets going good. This shipped quick, got in 5 days. Bought from here before very good place to do business
