I sprayed my field peas with Select 2 EC grass herbicide the other day...same deal as with the clover. I used 10 ounces with 1% crop oil but less might have been enough. Rates vary depending on what kind of grass but I was only dealing with foxtail. 2008 ND Weed Guide says 9-16 ounces for Select Max or 4-8 ounces for Clethodim for control of annual weeds and quackgrass. Just remember to use crop oil and keep it agitated Peas seem to be doing well and the oats are headed out so killing them with the Select isn't going to matter at this point. Some had pods but the foxtail was starting to worry me a bit I'll check it a week or so and post results and I'll soon be planting a second patch that should flower during cooler weather that should yield more peas this fall.
