Ok I Give!!!!!

I have been using Ranger Pro 40 something % Glyphosate and a dish soap as a surfactant for gross weed control, spot spraying for quite awhile. Usually do a spring spraying when the weeds get up and going. Temps in the high 70's.

Got to reading on here, forget where, in this section as I recall, about pond management and came across a guy who said he used Rodeo and a surfactant. So I bought a 2 ½ gallon jug of Rodeo which seemed to contain the same percentage of Glyphosate (don't know what else in the mix) and for the first time a professional surfactant, a concentrated quart that sold for about $45 bucks, but being concentrated, didn't take much.....helps to justify the price.

Application was per the container instructions, using the average numbers...like if it said 1-3 oz. I used 2. The weather was in the mid 90s for daily highs. I sprayed in the mornings when the wind was down as usual in my usual spraying manner.

Results were amazing. Really a hard kill.

So the question is...........what caused it; the brand of Glyphosate, the professional surfectant or the brand of surfactant, or the warmer weather?

The right surfactant along with following the label for whatever your after always works best I have found.

Since if i remember correctly Rodeo is for use in ponds, I would guess that whatever the ingredients were besides glyphosate made the difference.

I think duns right.

Sometimes the stars line up. ( Referring to your luck with the herbicide, not dun being right)

That would be in category of even a blind hog finds an acorn once in a while

Labels I googled....
ranger Pro has active ingredient of 41 % with surfactant included
rRodeo has active ingredient of 53.8% which probably made the Rodeo mix more potent with your averaging. Growing phase of target plants may have allowed a better kill also. That one shows up more when your applying near the minimums needed to be effective. Their was quite a bit of difference in some ragweed I sprayed with a quart of 2,4-d prior to a good rain when compared to some I sprayed several days after.

Hmmmmm. Guess I missed the surfactant in RP. Bought a box with 2 ea 2.5 gallons years ago and on the second jug. Will investigate. Thanks

The thing that makes Monsantos branded Roundup so good is the surfactant. Hint, They don't use dishsoap.
The good surfacnt prol made all the diffrence. The higher % of AI might have made a diffrence but I doubt it.

I agree. Just wanted to hear from somebody that knew from experience. At $45 a quart vs $2 for dish soap, one needs to really believe in what they are buying. I'm a believer! Thanks.

There's cheaper stuff than 45 a qt. keep looking.
I actually run a generic rup that needs no added surfactant.
