Milestone Specialty Herbicide with Aminopyralid for Noxious and Invasive Weeds-Quart 6666085

ProsFor broadleaf control in turf, seems to be +99% effective when broadcast-applied at recommended rates and under ideal conditions.Still very effective even under non-ideal conditions.Assuming clay-loam soil, with moderate precipitation beyond regular irrigation, treated area will remain almost entirely weed-free for at least three months of a growing season.Has both post-emergent and pre-emergent effect; kills both by initial absorption through foliage and by root uptake after it's washed into the soil. If by bad luck it rains shortly after application, it's not a total loss; it'll still put on the hurt by root absorption.Does not harm turfgrass at all, even at maximum rates.On the contrary, and mysteriously, has a sort of slow-release fertilizing effect.Extremely cost effective on an ounce-per-acre basis.Seems to kill just about every type of turf broadleaf weed.Fast acting: weeds begin to die 24 hours after application.It's damnation to thistles.ConsBecause it also kills by root uptake, and remains active in soil for up to a year, and sometimes even more, NOT TO BE USED OVER ROOT SYSTEMS OF DESIRED BROADLEAF (DICOT) PLANTS (that includes trees).It's passed unchanged through the digestive system of livestock. That means their manure is toxic to broadleaf plants.Mixing rationale is non-intuitive for most people; it's based on ounces per acre (regardless of amount of water added) rather than ounces per gallon. (This product is directed to large-scale, broadcast-spray use). When broadcast-spraying, you'll have to know how many acres your sprayer tank can cover, figure how much water to put in the tank for the acreage you want to cover, then figure the ounces needed for the acreage.Not as deadly to plantain as to most other weeds (still plenty hurtful).This stuff is simply incredible. I broadcast-sprayed a sports field that had large quantities of clover, black medic, hop clover, some buckhorn plantain and dandelion, and a few other kinds of weeds (e.g. thistle). Conditions were very good: late spring, about 75 degrees, humidity not too low (maybe 55%), very little wind. Also, there was no rain for several days after, and I did not irrigate, but I misted the field a couple of times in the next 24 hours, just to rewet the foliage, in hopes that any herbicide left on it would get a second chance to be absorbed. Application was made at the rate recommended for clover: 5 ozs per acre. A small amount of non-ionic surfactant was used (don't use dish soap!). One overlapped pass was made, then another non-overlapped pass, perpendicular to the first, using a coarse-droplet spray head. Three weeks later, of the five acres treated, you could count the surviving number of weeds on the digits of two hands & feet. As of three months later, there have been just about that same number of new weeds that have managed to get a foothold.Have used it in many other places (always in turf), and under less-than-ideal conditions, with comparable effectiveness.Have found that, for spot-spraying, or small-area spraying with a backpack sprayer, 3 ozs to 4 gallons of water is just about right.Makes Trimec, 2-4,D and even glyphosate look like a joke. It's more than three times as effective (not even counting the residual effect), and more than three times lower in price. Let's do the math.You'd need seven 32 oz (one quart) bottles of Weedstop (a popular Trimec) to cover one acre at the rate recommended. One quart of Milestone covers almost 6.5 acres at the 5 oz per acre rate that I used. So you'd need over 45 bottles of Weedstop to cover what one bottle of Milestone will cover. A quart of Milestone is going to set you back ca. $95, but 45 quarts of Weedstop, at $7 per quart, is $315.You'd be an idiot to keep using Weedstop...but remember the cons above. Read the entire use directions and cautions!Update: Almost one year later, my sports field is just as weed free as it was shortly after I sprayed. I'll give another update at the end of this summer (2017).The update is late (July 2018):At 5oz per acre, the residual effect of the original turf application petered out after about 1.5 years. Very respectable performance! Have learned a few more things from experience.Extremely Sensitive Plants: Grapes, tomatoes. Don't even let the smallest wind drift get on these!Sensitive Plants: Even spot-spray use around certain ornamental shrubs is a BIG no-no. They can feel the hurt more than two years afterward (leaf curl). Ditto for some maple trees (not so much Japanese maples).Less Sensitive Plants: Some fruit trees (plum and pear; don't know about others) don't seem to be affected much, if at all. Most conifers also seem to be quite resistant (inludes arbor vitae). Asian knotweed is somewhat resistant. Some shrubs, such as barberry or boxwood are resistant.As you would expect, the bigger the plant, the less harmed.The above list is obviously just rough details on a few plants. Experiment at your own risk. Of course, safest course is just don't use it anywhere in the root zone of desired dicot plants.

This is a great product it took care of all the broadleaf weeds I needed to kill for my clients.

This is the greatest product ever! I bought it to use on my lawn. I was a bit scared of it since it’s really only supposed to be used for agricultural uses, but I had a whole bunch of Canadian Thistle spreading and multiplying and had no way to kill it. Roundup only wounds Canadian Thistle, but this stuff kills it dead!I used one of those hand pump sprayers that I bought at Home Depot, filled it with a gallon of water, and added in one ounce of Milestone. Then I walked my yard spraying it evenly across the entire lawn and maming sure I got every weed wet. It took about 6 gallons (which is 6 ounces of Ilestone) to do my half acre yard.I applied it 12 days ago, and all the Canadian Thistle, dandelion and other broadleaf weeds that were in my yard are GONE! It didn’t harm the grass at all. My yard looks fantastic, and for the first time in three years I don’t have any Thistle in my yard. Just be careful around your trees and flowers. I kept about a three foot diameter away from all my trees, and made sure that when I was near my flowerbeds I was really careful not to let any spray go near them. Make sure there isn’t any wind when you spray so that the mist doesn’t blow onto your plants or trees.The bottle of Milestone is expensive at $100, but I still have plenty left to do a second or third treatmemt down the road, so I figure it really only cost me about $30 do cover my yard. That’s cheaper than trying to do weed n feed (which wouldn’t have done anything to kill the Thistle).Don’t be afraid to use it on your lawn. It works GREAT!

I learned about this herbicide from a hobby farmer who worked on the landscaping crew I hired. I had mentioned that I had some Canadian Thistle that I had tried to get rid of for at least 10 years. Just about the time that I thought I was the victor...some new plants would appear. It is the WORST weed that I know of. It grows to be tall and is covered with "tiny pin needles " that even prick thru heavy garden gloves. It's invasive and VERY hardy - it even survives full-strength applications of Round-Up! I've read it is so hardy it can grow roots 20-feet below ground to come up and find a new place to invade. (I believe it spread to my city yard from a neighbor's yard. We all have nice, well-groomed yards and gardens. There is no place for this awful stuff)! This landscaper/farmer commented that this herbicide is the ONLY thing that kills Canadian Thistle. The ONLY thing because it is the only herbicide that will kill the roots. I learned that if you don't kill the roots you can't get rid of it. He said it was available at farm supply stores. (Hmm - this City Girl would not know where to find such a store...!). But I found it on Amazon! That was a surprise! Granted it is expensive. especially when very little is needed! But I found it to be well worth every penny! I bought a pressure sprayer and mixed the herbicide with water according to directions ( literally about 1.5 tablespoon to a gallon of water). I sprayed the weeds, of course taking care to not have it land anywhere other than on the Thistle. Within 24 hours the weeds were wilting, and within a few days - DEAD!. A few more weak shoots came up in obscure places....but other than that THEY ARE ALL GONE!. I feel like I witnessed a miracle. I am SOOO pleased! This bottle cost over $100. I think I used about 3 tablespoons. I have no idea if I will ever use it again. Nevertheless to me it was worth EVERY PENNY! I would like to find the landscaper/farmer just to thank him. (I am not sure what else it works on...but it sure gets rid of the Canadian Thistle). Signed...A Grateful Avid Gardner With No More Canadian Thistle
