I've read elsewhere that 5-6ml of the undiluted concentrate applied directly to the center whorl is effective in eliminating yucca. Is this factual?

Carl, I've never applied it to yucca, so I am not qualified to provide comment. You could certainly give a try on one or two. Good Luck!

Yeah that should do it. Its very powerful and effective. Make sure you don't get heavy rain for a few days after the application to give it time to soak in.

I don't know about the affects on a yucca or use of full strength but I can tell you that in a slightly more concentrated ratio than recommended, it obliterated everything it touched. I would try 50/50 first before going with full strength anywhere. Note, it was the only thing that completed killed the creeping weeds I was trying to kill but I lost a lot of lawn as collateral damage. Now the lawn is back and the weeds are not.

It seems like a really simply operation. My only concern for a homeowner is that you would need to know the correct percentage/dosage, how to safely handle the materials and there would be concerns about children or pets if the concentration were to high and if the cotton balls we saturated.

Well 100% ? Its hard to say what they put in it . Im gonna rake a guess and youre conducting an experiment involving extraction. If you are try heptane instead . VM&P; works but it takes a bit longer to evap out.

The concentrate is mixed about 1:6 with water for use. It should be reapplied every 2 months. It works.

The answer that I've heard is not very much. Judging by how small the quantity you get compared to a gallon of product you use it with, it must be small indeed. I used it. Did it do any good? I have no idea. I killed my weeds when I used it, just like I killed my weeds when I didn't. This is one product that would take a lot of scientists doing a lot of controlled experiments over a long period of time, to verify. To muddy the waters even more, I've heard liquid dish soap does the same thing, so I throw in some dish soap with my weed killer. Does that work better? I have no idea. Sheesh!

Definitely shorter time... diluting it just makes it ineffective. It is an acid so in order for it to be effective, you need it to be acidic.

Yes I have had very good results with this, better than other methods. I have had them out for about 2 months now and I started seeing results after about two weeks. I will change the after 6 months to be on the safe side. I highly recommend this product. Remember to use enough product and place them in the areas you see the most concentration, in kitchens, bath and laundry rooms and close to electronics.

This is a Concentrate you must mix with water. The amount you dilute is dependent upon the individual situation. This was enough for a small garden of 20 plants for an entire summer for my personal application. An emulsifier could possibly be needed because it is an oil based liquid.(I use a small amount of dish soap)

Hi David. The instructions are in the booklet attached to the bottle of Roundup. It specifies and I use six ounces of the concentrate to a gallon of water and it is very effective against the weeds and sterilizes the area for an extended period. I hope this helps.

Dilute according to bottle instructions. Don't need any stronger. It works immediately and effectively. Highly recommended... And I know...I have 4 large dogs. One small bottle makes about.Two and a half gallons.

I've been using it for about 1 year. I usually spray around the plants close to the roots but when I spray the hostas and yucas I do get a fair amount on the plant. Haven't seen that it hurts them in anyway.

YES. This is a concentrated version that should be diluted with water. Very effective.

I noticed that many types of brush that I was trying to remove (e.g. poison ivy or honeysuckle vine) required 100% strength as supplied in order to knock out the plants so I did not dilute it at all for these. You might consider experimenting with various amounts of dilution to see if it will work on the types of brush you are trying to remove, but I would start as J. Messick says with a 50-50 mix and go to a more concentrated mix if the 50-50 mix did not do the job.

I didn't use both, but I'm sure the concentrate goes a lot further than the spray bottle. I used this up in like 5 applications on three potted veggie/fruit plants.

I've used straight Neem oil that comes in a spray bottle, (which is only about 15% neem). When you dilute the 70% stuff to the right strength it works just as good if not better. No plant damage, smell or pet hazard. And its 1/10 the cost! Highly recommend

Not sure. Directions don't say but probably more effective sprayed or dusted directly on diseased shrub etc.
