I'm in a similar battle with wild parsnip. It spreads like wild fire and in the last 5 years its taken over every ditch and CRP field in Iowa. I have som nice CRP planted in native wild flowers and grasses that I'm trying to save. I'm also getting Canadian thistles and common mullins as well.. i put a 15 gallon sprayer on my ATV and spray from it. I use some pasture spray I get at Tractor Supply .
