Hello. Could napropamide based herbicides (devrinol) may be safely uesd in established blueberry plantings mulched with sawdust. Is the uptake of the herbicide by the roots present in the mulch possible. Could this results in the plants damage ?
Outside United States
These herbicides are considered very safe and are registered for use in new plantings. I have never seen injury in blueberries from this material.
If it was applied over sawdust I would expect most of it to remain in the sawdust.
