We are starting to see infestations of maggots in greenhouse transplants that look a lot like what we saw last year, which led to field infestations that probably started when growing the transplants. However, this year reports are coming in about 2 to 3 weeks earlier. Several species from the same genus (Delia) cause the damage.
