What are you guys adding to your backpack sprayers to speed up the kill of weeds in beds, driveway cracks, etc? Diquat + Gly was suggested by my dealer. Never heard of Diquat but will be checking in. Do you remember the rate and cost?

so it appears that diquat is the product that is added to gly in pre mixed solutions like razorburn and quick pro. anyone used these products? is it cheaper to by razorburn or gly and reward and mix your own?

used Quick pro for years nice offered, works super great, but for beds it is not a good idea i found the general dicline of the plants from repeated use of the diquat in it. this has been the obvservation of many i have heard. just my words of caution.

Roundup with a surfactant is you best bet. Reward which is Diquat will give you a really quick kill but if you mix it with roundup you defeat the purpose of the roundup. The roundup must be translocated to roots and stolons. if you burn the plant down the plant will wilt before the roundup is translocated. The surfactant helps break the surface tension in the leaf tissue and lets the chemical get into the plant better. Razorburn is roundup and reward, but becareful with using higher rates because you defeat the purpose. Try adding a surfactant and a pre-emergent and this will give you better long term results. Be cautious of the "Quick Kills"

Welcome to LS it is always good to read a post from someone with real knowledge. Monsanto Chemists spend years developing the Roundup Quick formulation using Diquat. I believe it is impossible to field mix Glyphosate and Diquat and get the same results. You are only wasting the Glyphosate.
Scythe ""Pelargonic acid"" doesn't burn quick enough to stop the Glyphosate from doing it's job. However you will never read that on a Monsanto Label. I am not sure of the reason but Monsanto never even looked a using Pelargonic Acid for corporate reasons. Pelargonic Acid is only made in Germany and is a very cheap chemical.

Time for you to shop suppliers. I am paying right at $ 40.00 a gallon for Scythe in one gallon bottles. 2.5 gallon jugs are even cheaper but I don't use that much in a years times because I don't offer weed spraying in beds.

is scythe not so harsh as diquat? diquat started to buildup in the soils after prolonged use and it was noticable. i switched back to gly with surfactant(not name brand any more) but the addition of scythe to hasten the kill with no ill effects would be advantagous. please more info on the long term effects of this with round up and beds

Diquat has an Aquatic Label and only has a 8 hour half life in water. Therefore I find it hard to believe it will build up in the soil which also has water. Glyphosate also carries an Aquatic Label if no manufactures surfactants are added and goes inert almost on contact with water. Both Chemicals will get eaten by Microbial after they go inert. IMHO neither chemical is a major problem with residual.

so i went with octane instead of scythe. my dealer said some of the guys that tried scythe said it gave them a headache, but all they had was a 2.5 gallon jug and I didn't want to "try" something that expensive.
I had thought about gly with surfactant also. Sprayed some octane today so we'll see what happens.

Any body ever use ivory snow dish washing liquid for a surfactant? I have tried it and it seems to work pretty well.

it has surfactants in it, and i appreciate your input, but why did general plant health steadily decline and now i stopped using it they are better. i have heard this from others on here too. i guess it would be surfactants. i know it is not the gly, i am aware of how it works and why, but not the diquat. according to your comments, wouldnt it be the surfactants making it stick around longer than normal to cause this?

I add sureguard- $250 bucks worth does like 500 backpacks. Not recommened for planting beds though. I don't use round up though. I get credit extra. Same stuff as round up- you have to use a little more in the mix, but it is like half the price

Sorry I can't give you an answer. I know we have a few Palms that response unfavorably to Glyphosate. I don't know if it is the Surfactant or A I that causes the problem. But I have never had a problem with Glyphosate stunting any of my ornamentals.

no issue like that either with gly and surfactant only, but with the diquat the shrubs got thinner, and overall health was just less, hard to describe but they were. so i stopped using it and it is all better. i do hate though waiting a week for weeds to die though, the quickpro def spoiled me and my customers, so you sure sythe does not have any ill effects like the diquat did, i may give it a try but would like your take first

There could be a synergistic effect between the two. However, it would make me wonder why monsanto would manufacture them together and not put something on the label about use in ornamental beds if this were the case. As Ric was saying about the palms, I did read an article in Landscape Management magazine this past year that said studies were showing that repeat use of Glyphosate around the base of trees was showing signs of damage from uptake. The damage was appearing like freeze damage. Just something I read...
