Imox Mix

I’ve ready a lot and studied both crop oil and surfactants. And, when I ran the coop many moons ago I sold more crop oil than surfactant. The herbicide label should be your guide. Research would tell the effectiveness of each used with the herbicide in question and the weeds it is labeled to control.

Having said that, the line between the two adjuvants is murky. I’m going simple here and will be technically wrong in a general way. Each weed species has its own leaf surface characteristics designed to minimize loss of internal “good stuff” while maximizing protection against intrusion of “bad stuff.” As growers, our need is to defeat both systems. Surfactants and crop oils are good for the job. Which is better depends on the weed and herbicide mode of action.

Personal experience? Always crop oil for me. Can it burn? Yes, but rarely at recommended rates, usually 1% of the mixed spray solution. While there’s no scientific evidence for what I do, I will sometimes up the percentages of crop oil where there is an immediate threat of rain and/ or where weeds are beyond their optimum kill size.

Bottom line? I dunno....
 
Actually the only time I've seen crop oil burn clover was when I inadvertantly added to a new gly that I unfortunately didn't pay attention that it already had a surfactant in the mix. And the clover just looked ugly for a couple of weeks and rebounded with no problem. You can hardly kill clover even when you want.
Now a question, I wonder if a person sprayed a crop oil mix only, if it would inhibit weeds on its own without other chemical additives?? I'm thinking it would, at least to some extent.

It probably depends on the variety of the weed.
We always hear the saying about cockroaches and rats being the only things that will survive a nuclear blast. I think there are a few weeds that should be added to that list.

Peeing on weeds will probably set them back for a while! What brought this to mind was remembering what UAN (liquid nitrogen) did to corn and weeds when top dressing the corn! Don’t ask me how the two are connected. I suppose crop oil in a large enough quantity could burn but so can a flame thrower. Good question though!
 
Peeing if not localized might increase production as it has high content of Urea which we spend good money for.:)
I was thinking crop oil might work as some people/not me might have once poured oil on fence lines to kill vegetation. Don't tell the EPA. Just thot maybe lower quantities in spray may set back weeds. I see and experiment inthe future.

Perfect!
 
Just an update note, if you use Imox expect it to act slow much like Cleth, needing 2-4 wks for a kill. I can see results on most areas beginning ,even slight set back of some thistle but I doubt it affects it much in the long run. Like Cleth, I think it is harder to get a good kill in years when rains are frequent and plants are so healthy as we are having this year. I took a pic but it didn't come out to good. Will followup in couple wks when I get down there again. So far, as for just grasses, I'd use the cheaper Cleth in the future. But for weed control which is my intention this year, Imox seems like a relatively cheaper alternative to other sprays. It was a good year to spray as my mowing control for weeds is a disaster with the fields a wet mess. Plots do love the rain tho. Won't complain.
 
If you look past tree you can see grasses and some weeds dying. Clover is about a foot deep beneath. Alfalfa hanging on.

Agreed, my experience with Imox is that it takes a while before you see anything. It’s also very slow and killing stuff off. If you want to get rid of grasses use some sort of Cleth 100 percent.
 
Sprayed IMOX Saturday on a smart weed plot...I mean clover plot! It sat for about an hour and then a pop up rain storm came. It poured for about 30 minutes. IMOX should be ok in that scenario wouldn’t it?
I sprayed cleth on another plot about the same time. I don’t have high hopes for that.

I'm skeptical. 30 minutes of leaf contact is rarely enough and IMOX is very water soluble. Did you use a surfactant or crop oil?
 
Dead isn't all that wow! To do the job, herbicides don't need to kill immediately - or kill at all. The herbicide just needs to stop the weeds from competing with the crop. Of course, eventually, a lack of food and water will cause the weed to die, but it stopped playing long before.

I used a crop oil. It sat for an hour before a 30 minute storm.
Would you feel comfortable just spraying it again this weekend? I hate to wait 2-3 weeks before seeing if anything happened.
 
Its been a while since I read the complete Raptor label, but I seen to recall 2 hour rain fast. No?

What rate of IMOX? ounces per acre equivalent? And maturity of the clover? There's a 14-day wait period between applications should you wish to know the label instructions....

I need to look at my notes at the farm honestly. I can’t remember offhand. The plot is small. Maybe 1/2 acre and the clover was planted in early April. Doing great with the exception of an amazing amount of smartweed!
 
Clover planted this spring? I don’t think I would have had the courage to treat it with IMOX. A second application, I think, is out of the question

Honestly it’s no great loss if I have to start over with a fall planting. I just purchased the property in January. This was a shady plot and I was just trying to get something established. I girdled several large trees that were shading out the plot in March. It’s best times are ahead of it cause it can’t get much than when I started!

The rain shower at 1 hour shouldn't be any problem with the herbicide working. Once an applied herbicide has dried on the leaf it's finished working, the plant has already absorbed what it will absorb and rain won't make a difference anymore. That's why the herbicide application method is so important, a mist that uniformly hits all the leaves of the entire weed will cause the weed to absorb a lot more active ingredient before the spray mist dries than an application that is spraying in droplets and isn't consistently hitting the entire leaf. Spraying in the morning when there's dew on the leaves can also help to get a better kill rate.

Excellent info and good piece of mind for my situation. Fortunately I was spraying with a good dew on the leaves. I sprayed the imox on my smartweed plot and cleth and my Johnson grass plot so we will see. If Johnson grass was currency I would put Arabian oil sheiks to shame.
