Potted Blueberry and Systemic for Thrips
I've been fighting thrips for 2 1/2 years now and I think they are getting used to Spinosad. It doesn't seem to knock them back like it used to. Wondering if there are any systemic pesticides I could use after harvesting fruit for the remainder of the growing season and use Spinosad from bloom to harvest. The thrips really like my SHB but leave my Rabbiteyes alone for the most part. All my SHB are in pots with the exception of 1 and I could do a soil drench on all my pots. Any thoughts or recommendations?
