Wondering if the frost row covers that folks use would provide a level of protection from herbicide drift? Yes I know they are breathable, but if they work well enough to trap some level of heat might they also “catch” the spray drift before it reaches the plants? I have a few table grapes that got slightly burned last year by a neighboring farms herbicide drift. I would remove the row covers once we are past the primary ag spraying period. Anybody have direct or indirect evidence that this might be feasible.
No experience, but it sounds like a good idea. There is no pressure and very little weight in the drift, so there’s little to force it past the fabric. I guess my biggest question would be how to get it off of the row cover- washing might carry it through, and I doubt you’d want to leave it on, or discard the row cover.
What you really need is an herbicide neutralizer!
