I had 2 acres of the prettiest Eagle Big Fellow RR soybeans . They were about 10-12" tall when I sprayed them with Cornerstone Plus.(2oz to the gallon) , When I came back a week later everything was DEAD. Anyone ever experience this???? I thought Eagle beans where dummy proof... any idea what I did wrong?

I have used regular cornerstone for the last few years with no problems. Could it be the PLUS?

Does it have something else in it?

Just has a surfactant in it ..

How many gallons did you spray on the fields? It's important to know the ounces of herbicide per acre in most cases. Do Eagle beans have a label with herbicide recommendations?

Just curious, since they are roundup ready, why did you use cornerstone? Did you plant something else with it. I've sprayed peas in my garden with something labeled for peas mixed a little stronger than recommended and killed em dead

Cornerstone is round up, glyphosate..

I sprayed 22 gallons on the 2 acres.

But the key is how much of that 22 gallons was gly? The amount of water doesn't make much difference.

Those generic glyphosates are all formulated a little different. Any of them will work for burning down deer plots, but some of them are not meant for certain crops. I had a chart that showed which brands were suitable for various crops, but I'm not sure where it is. As I remember, Cornerstone is not one of the better formulations for crops.

All this is from memory and could be wrong. Might just be a simple overdose, but I'm sorry for you whatever the case. It's a bad feeling to ruin a crop.

Edit- sorry, I missed you saying it was 2 oz per gallon. That doesn't sound like too much. Gonna need one of the Ag experts on here to answer this one.

That's less than a 2% mixture. Recommendations are typically 2.5% mixture. I will safely spray beans hot with a 3-4% mixture if there's a lot of nut grass. Either there was left over chemical residue in your sprayer of a different herbicide, your beans were not round up ready or something else. The mixture you made though was on the low end if anything.

I agree, I purposely mixed it weak... I'm bumfuzzled about it... I've never had anything in my sprayer except Poast Plus and Glyphosate

I do 40 ounces to 25 gal of water and never had that happen....I run as close to 6 mph as I can that just puts a good mist on things and the 25 gal sprayer does right about 3 1/2 acres. I think I'm on the light side of application but it works so far.

I think you were given the wrong seed. If they were truly a RR variety, Cornerstone would have had no effect on them. Either that or you had some residue in your tank from something else.

Did they turn yellow and die or did they curl up like they were growing in circles and die?

Have you sprayed any other herbicides out of your sprayer previously

When I came back there was pretty much nothing there, so I can't say if they turned yellow or not..

Only thing previously was Poast Plus but a tank of gly had been ran through there before I sprayed the beans..

You can spray 5x rate of gly on RR beans and not hurt them. Cuz I'm afraid you had something in your sprayer or something else wrong.

This is my vote.

Deer ate them

Appreciate the input , still scratching my head... deer didn't eat them, I have 1.5 acres of iron clay mix around them that are pretty as can be

I've seen deer wipe them out like that. They prefer soybeans over peas.

I would call recommend calling Eagle Seed and ask if anyone else has had the same problem. Sounds like wrong seed if you can rule out issues with what was previously in the sprayer. Calling them might at least help solve the mystery. I've had good customer service with them in the past.

I've never planted peas; however, thought I have read they won't touch them until a certain point, but will take them out quickly once they reach a,certain stage.
