2,4-D injury

[Bkat]

The dreaded herbicide drift has descended with all the telltale signs. Leaf curl and stem twisting. So pretty sure on that. My question is, will the grapes be safe for consumption or does this season's yield need to be destroyed?

I suspect there are rules on this and actual science about how an effected fruiting vine metabolizes herbicide exposure. 2,4-D is not approved for use on grapevines (for obvious reasons!) so I'm looking to hear feedback from forum members who know this stuff and not responses that just say "I'd eat them and probably not die." Thanks!

2,4-D is a plant hormone that causes the plant to grow faster than its vascular system can support and often the herbicide includes fertilizer to enhance the effect.
