Has anybody sprayed this on their hayfields. Ive read the label front to back. I have put 1-1.5oz per acre and sprayed on a sunny day within the 7 day window from cutting the hay. It is supposed to clean up the majority of anything but Bermuda grass, but it has been almost 2 weeks and I can't hardly tell any difference or die-off of anything in the field and i'm certain their is foxtail and crab grass in the mix. TIA

What surfactant?

I have sprayed an approx 7 ac area (horse pasture) where I had some trouble with grass competing with Bermuda. No other experience. It worked for me (just 2,4-d now for broadleaves).

Far as I know, no surfactant needed. I can't find a weed in this field so i'm not spraying a broadleaf herb. and it's produced 31 - 5x6 bales on 6 acres. From what i've heard, the pastora would blister about anything but bermuda, just stun bermuda for a couple weeks. I may spray again in the spring when everything is more tender and use a surfactant to just be safe.

I always use a surfactant with pastora, 80/20. Always takes a couple of weeks to notice it working. It’s not like 24d or round-up where you notice wilting almost immediately. This late in the year with no surfactant weeds are tough to kill.
