True, it's not straight gly. But, when you buy straight gly from the farm store it must be mixed with water. You end up with same thing, but buying straight gly is cheaper. That may be what you meant, I wasn't sure. I didn't want anyone going out and spraying straight gly on their fields.
It's also very helpful to add a non ionic surfactant to the srpay mixture. A lot of gly claims to have surfactant in it, but it's not a non ionic surfactant. It makes a difference. Some people add dish soap in place as a surfactant. It may help, but it's still not the same.

Thanks everyone for clearing that up for me. I planted soybean and corn last year after spraying, disking, harrowing and spraying again over a 4 week period. My plants grew beautifully for the first month and then the ragweed started and it took over both food plots. The land had laid fallow for 12 years after many years of being farmed for corn. I limed and fertilized the soil and everything in that regard is optimal, I just need to get these weeds taken care of this year so my plants yield food. I considered a controlled burn folowed by spraying repeatedly because the ragweed seed bed is so thick.

Has anyone else had a problem with Round Up not killing certain weeds. There are some really small weeds that almost look like clover that Round Up wont kill on my plots.

That's not uncommon. Glyphosate is most effective on grasses and won't kill everything. There are some broadleaf weeds that show very little affect from glyphosate. Sometimes you can up the rate. You can just mix in some 2,4,D and kill it all, if that's your goal.
If you're spraying Round Up Ready crops and don't want the 2,4,D, try adding a non ionic surfactant. That can help considerably.

Arrest herbicide can be used on plants (clover chicory and alfalfa) that have already started sprouting right?

Yep, the Arrest is a grass herbicide.

Has anyone ever used WEEDAR 64 or PBI Gordon's LV400 2,4-D?
I found the WeedAR for $48-2.5 gal and LV400 for $39-2.5 gal. I will be planting corn and soybean in the field after spraying, harrowing and spraying again. The LV400 states it can be used for clearing weeds prior to planting grain crops. Just wanted to know what you guys thought about these products and if one is more effective than the other or what your experience was using either product. Also, will I be able to kill PigEar weeds by continual mowing in my clover plot. It is in it's 3rd year of growing and reseeding every year. The clover is thick and healthy but the PigEar seems to be multiplying. Do I have to spray each individual plant with a root killing herbicide to ensure it's death?
