Peter – Really enjoyed your talk at East Greenbush and learned a lot about organic solutions. Forgot to ask – would Captain Jack’s Dead Bug Spray be useful to combat the borers in my blueberry bushes? Thanks!
There are a couple of borers that can affect blueberries. The flathead borers which have no spray that can control them. There are some cultural steps you can take to minimize the damage. HERE’S a link to information on that. and another LINK that may be helpful.
If they are tip borers then a pyrethrin spray (pyrethrein is found in the Bon-Neen product we sell) can be helpful. HERE’S a link to more on tip borers.
