Spraying Roundup on manure piles
Can I spray Roundup (or similar chemical) on a standing manure pile to kill off the vegetation that has sprouted up in the piles?

Yes, the active ingredient in Roundup is glyphosate and it can be used safely in this way. Some formulations of Roundup contain other active ingredients and surfactants. Be careful about using them as they can have a longer residual effect. Read the label completely before buying or applying any herbicide.
