Saving my rhubarb

Perhaps call your county extension office to see if rhubarb is safe to eat growing so close to where herbicide was used even next year. I think this is a great question to ask by people who use weed and feed type products. I would contact the company, too. Should be a phone number on the package.

I doubt there's an antidote per se, at least not a commonly available one, but watering heavily will at least help flush the stuff away sooner rather than later. How badly it will/might affect the rhubarb depends on the specific herbicide(s) the product contains and how much of it the plants were exposed to, but generally speaking, any herbicide that kills dandelions will also affect rhubarb.

As for not eating it while pregnant, you probably don't need to avoid the rhubarb the whole season (unless you eat exclusively organic produce to begin with, you're getting some exposure to pesticides anyway), but you should, needless to say, check with someone authoritative about that - the manufacturer, as dfrostnh suggested, your County Ag Extension office, or maybe even your local Poison Control Center (you can find your local center at www.aapcc.org/ or by calling 1-800-222-1222.)

I don't know the extent of your dandelion problem, but if individual treatment is an option, a hit of white vinegar (about 1/3 cup per plant) will take care of them. Also melts thistles.

So it turns out there wasn't weed n' feed on my rhubarb after all, as best I can determine. We have some kind of insect eating the leaves and stalks, which makes it look wilted but I couldn't see any of the fertilizer pellets around the plants.

Thanks everyone! I've been enjoying lots of rhubarb sauce on my yogurt while I can. Last year this plant produced into July. . . which is why I wanted to save it
