What is a good pre-emerge chemical on Soybeans?

Update*. We settled on generics of Dual and Sencor.

What is a good pre-emerge chemical on Soybeans? We've been using Sonic (Sulfen Cloran), but we've had too many situations where we feel the chemical has hurt the emergence. We disk corn stalks in the fall and field cultivate in the spring, and spray a Liberty/Roundup mix postemerge.

In our area where guys use sonic we use 4oz sonic + 4 oz metribuzin + r/up and low vol or dicamba depending on timing and bean trait.

6oz Zidua Pro + 4 oz metribuzin does a great job... however its a cadilac program and probably not needed for full tillage systems

I like the Authority products and have had good control with those. Add some Sharpen to the burn down and that will clean it up

We’re wanting to find an alternative to the Sulfen Cloran products (ie. Sonic, Authority, etc)

Fierce XLT is a top shelf long lasting broad leaf product. Always adhere to the label as it contains the "Classic" Sulfy ingredient.

We have used Surveil, intimidater, and gramoxone and dual mixture. They all worked well, it all depends on the rain

Valor worked great for me, in no till.

We love Zidua Pro with some metrobuzine. Have had great luck in our higher weed pressure acres the past few years trunning that program.

I use 8-10oz of Verdict with MSO and 1qt of Roundup Powermax.
