Zidua will keep most pigweed from coming up. Not labeled for alfalfa, but zidua will not kill anything can be sprayed post emerge on soybeans and corn. No harvest restrictions for grain soybeans and a 37 day harvest delay for sweet corn ears for human consumption.
Would use pre after 1st cutting and may need to use more of something after all cuttings.
Have you added a trizine to the paraquat, seems that is the only way we get a good kill on pigweeds after wheat harvest.
We have not used anything on our alfalfa for broadleaf control.
Prowl seems to be NAT approved for soybeans for pigweed control, but when I talk to Gick Fleming he always talks me out of using it.
