The past two years, water hemp really comes on strong when we get a mid-August rain. The water hemp overtakes the bean/brassica mix in a larger and larger portion of the plots to the point I know consider it a problem.
I was planning on drilling wheat this spring to provide a little nutrition, tilling it under in early/mid June for a green manure, spray 2-4d (when the weeds start to show up and again right before I plant the fall mix) in an attempt to clean up the water hemp. Lastly, I was going to plant my mixture a little later say September 1st.
I don't like giving up a 2 months available food source (June 15th to August 1st and August 15th to September 1st), but unsure what else to do. Is there a better answer out there?

Plenty of other benefits, biomass, huge system and soil compaction help.

Whatever you do, I would like to know the results.
Good luck.
This year I planted 7 acres of Real World beans (shatter resistant northern variety) where I would normally plant Ag beans. The RR beans grew faster and taller and canopied extremely well you might try them. And as an added benefit the deer preferred them....not by a wide margin, but a noticeable one.
The second thought is to move your planting date of your brassicas back as you noted. If at all possible plant when you have excellent soil moisture and/or right before a rain. I did that as well this year and really made a sizeable difference.
The third thought is to fertilize the daylights (100 lbs of nitrogen/acre and 200 lbs of Triple 19/acre) at the time of planting. If you see any yellow or purple in the leaves then give them another shot of nitrogen right before a rain.
I assume you've done all the soil tests so your PH is good to allow the desirable plants to up take the nutrient and fertilizer at the best rate possible. Ag lime is good, Pel lime is better in my experience.
Let us know what you end up doing and how it works!

Just like when humans and animals get the same drugs on a regular basis, there becomes drug/chemical resistance. This is why your suppose to plant refuge acres instead of 10% roundup.
Alternative solutions are to plant soybeans and use pursuit on them. This is what we all used before roundup came out.
Another alternative is to use roundup and tank mix pursuit with it. There are products with this blend premixes and 2 products would be extreme and thundermaster.
