What if it rains within 6 hours of application? Will it still be effective?
barnie on Jun 12, 2016
BEST ANSWER: A ag specialist from local University helped our church with Buck Thorn infestation in Churches woodlot. He recommended 1 part triclopyr with 4 parts oil, he recommended Mineral spirits, it worked great, spray leaves on small stuff up to 4 feet, cut larger and paint the stump on big stuff. almost 100 % effective. Mineral spirits turns out to me more expensive than triclopyr 4 per gallon, would recommend using diesel instead.
Does Trilopyr 4 kill Autumn Olives ????
I have an uncontrolled growth of this terrible invasive plant from asia on my CRP sites. Do you recommend something mixed with Trilopyr and applied to the bark at the base of the plant ? Need help for this proble
Billy in Indiana on Jun 4, 2017
BEST ANSWER: I'm fighting 10 acre autumn olive jungle. I mix 13oz. triclopyr per gallon of diesel and throw in 4oz MSO (MES 100) for good measure. Spraying trunks up to 4". Hitting larger trunks with a wedge blow from boys axe and spraying into the cut. Works good but slow progress when you're dealing with acres. On big bushes, also spraying smooth bark branches at base helps effectiveness. 4 oz in gallon of water, w/ MSO, as foliar spray works on new sprouts up to three ft. or so.
Will triclopyr 4 kill rose hedge?
Tommy C on Aug 15, 2017
BEST ANSWER: Rose hedge is not on the label for this but many people do use it for it. Typically they mix with diesel and spray around october (if you are in texas) for best results. We recommend Imazapyr 2SL as it has wild rose on the label. Whatever you do, DO NOT mow it until you have applied a chemical to prevent spread. It will spread if you mow it without stopping growth.

If I remove a tree do I put garlon4 in the cambeam layer to kill the tree?
A shopper on Sep 15, 2017
BEST ANSWER: If you cut the tree as close to ground as you can, you can either spray garlon on the surface of the stump or brush it on with an old paint brush. It will prevent any shoots from sprouting and eventually (several years) the stump becomes brittle and simply breaks down.

I have a zoysia lawn with Bermuda trying to take over .. I've read that Triclopyr will kill the Bermuda but not the Zosyia .. True or Not?
If True, how do I best apply the Triclopyr to the Bermuda mix wise
MarkNTexas on Jun 6, 2017
BEST ANSWER: Alligare Triclopyr 4 may injure certain turfgrass species. Do not apply to bahiagrass, bentgrass, bermudagrass, centipedegrass, St. Augustine grass, or zoysiagrass, unless turf injury can be tolerated. It can injure both strands, however, some strands have tolerated the chemical I would suggest doing a spot treatment to see if it will control what you are needing to do.

really works on blackberries
I sprayed 3x this spring using a generic "round-up" and it simply was not working on the new growth sprouts where I cleared over an acre of blackberries last fall. After a google search I learned why and also saw recommendations for Triclopyr 4 which I immediately ordered on line. It arrived a few days later and within 4 days of spraying it I could see it was getting the job done. My only complaint is that I still am not sure how much to mix in a 3 gallon sprayer so that I'm not wasting chemical as the paper work attached is not very clear.

Replaces Turflon
Found this to replace Turflon. Same chemical but the price is much less. I also like the container that measures for you. No using tea and tablespoons to have to measure.

Shipping method
I have now ordered Triclopyr from you about 5 times. Each time I have asked you to send it ground. Twice you have mailed it via the US Postal Service; in both of those times, it arrived in 4 days. Two other times you mailed it via UPS, and in both of those times it arrived in 6 days. I hate to knock UPS, but for whatever reason, they are just simply less efficient than the US Postal Service. Just letting you know. When shipping ground to Virginia, the USPS is the way to go.

One other comment. In my most recent order I am spending over $200 on a 2.5 gallon jug. I have to admit I was surprised that you didn't bump my shipping method up to overnight or 2-day shipping as a courtesy. I expect that kind of service when I spend that much -- it is what I get from other online companies.
