? for soybean growers

Probably worked OK as I'm betting you had a decent amount of rain to activate the atrazine early on. If it doesn't rain to activate it it can sit there and activate later which could cause problems with your beans. This year was not a good year for clean fields. I have a field of roundup ready soy that I just gave up on keeping clean. Actually my old public variety soybeans are cleaner than the RR beans.

If it does work, provided enough rain, then it sure is cheaper than $17/acre for Envive and still have to spray prefix in 30 days anyway.

Best thing for marestail is a disc !!!!!

We have been using envive for 5 years and it was terrible this year. If it wasn't for us switched to liberty beans we wouldn't have been able to control the mares tail and water hemp. I will say that we can't ask for any cleaner fields after spraying once with Liberty though. Like ILGleaner said a disc worked great 4 years ago I disced 3000 acres with a 1435 sunflower ahead of the planter. That's a lot of fuel and work though and the next year it must have woken up water hemp that we never had problems with before.

We work all our ground twice. Once deep early spring and then again right before planting. The local elevator had not been as timely as we would have liked for them to be and sometimes it would rain and be two weeks before it got sprayed. So about 4-5 years ago we started spraying residual with saddle tanks and a spray bar behind the planter. That was dads idea. I wanted to just get a 60' pull behind boom sprayer. But from dads perspective it's really easy for me to put the saddle tanks on and off every year. But I digress. Ever since we started that we have reduced our roundup to one spray typically in late June early July. Some fields have been clean enough that we didn't spray roundup at all but most have needed roundup once just to clean them up. I will say we have had some of the cleanest beans that I can remember since we started spraying with the planter and a lot of the neighbors have commented on it. Before that we would always spray roundup twice plus an application of residual after planting.

With regard to mares tale and water hemp. We have had some wet years that didn't get an early disking in and got grown up. We still run over it twice, just disk one day, then disk again the second day and plant the third. On those years are when we have the worst weed problems. Seems like if you knock them back early and keep them knocked down whether it be with chemicals or mechanical it's easier to control.

We also have our own rogator and work all of our ground...our marestail problem ended when we went back to plowing in the fall...when ever I double crop beans I either use liberty beans or burn down the wheat stubble with roundup and sharpen and that seems to hold the marestail

We actually went back to moldboarding our double crop bean stubble a few years ago just to get all of the ground turned completely over every couple of years. Since doing that our marestail problem has been pretty well nonexistent along with quite a few other troublesome weeds we had been having....the sees companys just keep adding genetics to all of this stuff thinking that is the be all to end all answer to weed control...it's kind of like that movie Jurassic Park....nature will eventually find a way...all of these weeds will become immune to all of these chemicals eventually...everybody better wake up and realize that.

A little patch at the old home place was VT'd a day or 2 before beans were planted and may have been sprayed (glyphosate) a bit late. It's full of marestail.
 The rest of the beans were sprayed commercially and seem to be OK. They probably got sprayed a little earlier.
 Anybody have a problem with wild cucumber in RR fields? I sprayed my food plots (beans) and had a bit left in the 4 wheeler tank so I sprayed (glyphosate and volunteer mix) along the south fence where cucumber had started. One plant acted like I put fertilizer on it till I went back and sprayed with 24D

I think my problem was at burndown, burnt but not dead, and it regrew. Around here you DON'T use gramoxone on marestail. It will kill the leaves but the stem is still alive and after you run over it with the drill it splits the stalk and it regrows. If I can find a decent 20-25ft disk with leveler I would try it on all fields this spring. Just can't do it with a 10ft over 400 acres. Now I don't have weed problems on my double crop land, the wheat stubble keeps them pretty clean.

Great question. I knew a couple guys that had their own and it cost them a bundle.

You have them figured out to !!!!! They make more money putting a "Trait" in something. And keep there patent on , so you have to buy there seed every year !!!! They don't give a $hit if it only last a few years, they will make something else up, to keep the money going in there pockets !!!! And the co-ops love it, because they get to sell everyone sees, every year !!!!!

You can save RR 1 beans for seed , clean them and keep them, and pay no one anything.

You got it bud...we cleaned everything up with using liberty for two years and plowing and working the ground the last couple of years....this year I'm cleaning my rr1 beans and replanting those bastartds next year....now if a guy could just find some affordable seed corn we might be able to make some money with these ty prices.
