What can I spray post emergence on soybeans to get rid of water hemp. They only have Rr trait

20

Question

Answer

what stage are the soybeans at? it may limit you down to only a couple options. mostly burners. burn the beans and weeds! weeds are not resistant to iron yet if you have a cultivator around! I have seen cobra do a decent job on water hemp postemerge. keep the rate up.

Answer

I tried Ultra blazer after flexstar didn't and it did not work either so now I am convinced cultivating the rowed beans and walking the double row beans.I also applied Dual with the flexstar but we didn't have any rain  to incorporate it.

Answer

Are they roundup ready plus liberty link beans

Answer

I used Flexstar GT and added a qt. of Roundup worked very well

Answer

Save your money and spray if weeds are o ver 3 inches.  Just go and hook up  the cultivator,at least you know you'll get 80% of the water hemp

Answer

PPI resistant waterhemp if flexstar/ultra blazer/cobra didn't kill them. If roundup ready only -- like everyone says-- steel is your only remedy

Answer

Cobra is decent. Cobra with crop oil smokes everything. However, using Xcelerate (non-ionic surfactant) from Royal Oil will only bronze the soybeans. Xcelerate will also help glyphosate (or other active ingredients) do its best at standard rate. Not to overlook water ph and benefits of restructuring water for spray and irrigation using NuForce inline unit for best plant uptake / efficiency.

Answer

I used Zidia SC at 3 oz and it did a great job

Answer

Classic ****

Answer

If waterhemp are small 6-7inches tall 1qt glyphosate 4 ounces anthem-max has worked well

Answer

You must have a lot of faith mother nature too. ***** Pro the last couple years has been less than stellar due the extended dry periods after it was applied, leaving quite a few escapes to clean up with the post pass.

Answer

I grow all liberty beans. Have not run into anything that it won't kill.

Answer

Avalanche or Cobra think they are basically the same but different manufacturers. The burn will keep you sleepless for several nights.

Answer

I don’t think I would use Flexstar anymore. I believe it has a 10 month rotation to corn and I have seen flexstar damage to corn the next year. Plus I don’t think I would want to burn my beans now since they are flowering. A cultivator is your best option at this point.

Answer

Good luck we can’t kill late season water hemp or pigweed with Cobra,Ultra Blazer,Marvel or Prefix in RR1 beans the only thing that keeps us clean is Zidua Pro or Authority Supreme and it works very well but has to be applied right behind the planter and pray for rain to incorporate it before new weed growth ! I have enough faith in my pre emerge program now that I have switched to 100% non gmo

Answer

Had, the same issue, tried Cobra, didn’t work.  Not sure if anything will work.
