Hi All,
I have a grower who has had an ongoing issues with dogwood borer and would like to identify an alternative to chlorpyrifos. Does anyone have experience using Assail (acetamiprid) as a trunk drench to manage dogwood borer infestations in burr knots on Mark rootstocks? How effective have those treatments been? Assail 30 SG is labeled for a trunk drench. Mounding soil over the burr knots is not economically viable considering the acreage. Chlorpyrifos can be used up to 28-days before harvest for dogwood borer and would like to see that only as an option if we can't identify lower-risk alternatives. Thoughts on this?
