Does it kill grasses around the trees or just the trees?
A shopper on Jun 26, 2018
BEST ANSWER: Alligare Tebuthiuron 20 P is intended for control of unwanted woody vegetation such as
trees, shrubs and vines. Alligare Tebuthiuron 20 P will also control herbaceous broadleaf
plants such as clover or lespedeza. Grasses in the area immediately adjacent to pellets may
be temporarily damaged. Dormant season application is recommended to minimize herbicidal
effects on greases and other herbaceous plants. The herbicidal activity of Alligare
Tebuthiuron 20 P in soil may prevent the growth of trees, shrubs and other broadleaf vegetation
for several years after treatment.
Is is dangerous to wildlife and pets?
A shopper on Aug 13, 2018
BEST ANSWER: Not that I know of. It goes into the ground with .25 in of rain or more and thus is unavailable.
We put out approx 3/4lbs. active ingredient per acre in mar.The target plants were mesquite , nightshade , cockleburrs ,sunflowes ,etc. Have had about 6in. rain this summer , & i'm not seeing results yet . How long does this take to travel through the soil ? The type soil we treated ranged from clay to sandy loam

Apply Alligare Tebuthiuron 20 P at 3.75 to 5 lb per acre on the following woody plant
species (Note: On rangeland and pastureland, apply 3.75 to 5 lb/acre of Alligare
Tebuthiuron 20 P where a higher degree of control is required (see “Factors in Herbicidal
Response of Woody Plants” in the “Product Information” section of this label). Alligare
Tebuthiuron 20 P may be applied at rates as low as 2.5 lb per acre on sites with shallow,
rocky and coarse textured soils having low organic matter content, or where partial control
is desired.)
Is there concern about it seeping into the well system or say a small Creek that is used for irrigating?
A shopper on Sep 5, 2017
BEST ANSWER: With Tebuthiuron 20 P Herbicide and any other type of pesticide that is not labeled for aquatic use, you should stay at least 10 feet from a well or body of water. Apply when there is not chance of excessive rain after application to reduce risk of run off.

Will this product kill a large tree?
Me on Oct 2, 2016
BEST ANSWER: I have been told it will kill a tree; it may take several months to see the progress.
I purchased a 25lbs bag of spike 20p from my local farm store and I was wondering since it is in granulate form could it be mixed in a 2 gallon sprayer with water or do you have to put it in a spreader an spread the granulates out in the area
Bdugger on Jul 26, 2016
BEST ANSWER: Product Information
Alligare Tebuthiuron 20 P is a surface applied, soil-active product intended for control of
woody plants (trees, shrubs and vines). Treatments become effective after sufficient rainfall
has occurred to move the active ingredient in Alligare Tebuthiuron 20 P into the root zone.
Herbicidal symptoms appear more rapidly when applied just before seasonal rainfall.
Treated trees and shrubs (brush) exhibit leaf chlorosis and browning followed by defoliation.
Woody plants may undergo several defoliation cycles, usually following significant rainfall
before death occurs. Time required to achieve control of woody vegetation depends on susceptibility
of target species, rainfall and soil conditions and may vary from a single growing
season to several years. Increased application rates and additional time is required to achieve
consistent woody plant control under the following conditions: 1) the treated area contains
deep, medium-to-fine textured, or high organic matter soils; 2) the target species are deeprooted;
or 3) the vegetation consists of species tolerant to Alligare Tebuthiuron 20 P.

solutions review
I have used spike in the past and have had good control with it and it is safe a easy to use.. the cost of spike has gotten higher and I was looking for a less costly source when I found the solutions web site. I ordered the 25 pound bag, ordering was easy and my order came quickly and undamaged. I would order again.

Sound more powerful than it is
I used this product in the quantity recommended on the label and it didn't have the impact I was expecting on the vegetation I was trying to kill. I still haven't decided if I want to buy another bag of this to try again or if I want to buy a different product altogether.
