> To add some clarity to this discussion, fungicides are the chemicals of concern during apple bloom in my view NOT insecticides and the last time I checked there are no systemic fungicides. 

Systemic fungicides have been around for decades. 

> Honey seems to be especially susceptible to residues from fungicides used against pests in fruit trees and rape. Levels ranging between traces and 0.11 mg/kg of some systemic fungicides have been found in honey (Rexilius, 1986; Kubik et al., 1999). -- Contaminants of bee products Stefan BOGDANOV Apidologie 37 (2006)

>Bees frequently visit cherry flowers and both pollen and nectar are readily collected. Cherries are sprayed with fungicides during the blooming period, and thus are an excellent model for studying contamination of bee products. -- Pesticide residues in bee products collected from cherry trees protected during blooming period with contact and systemic fungicides Marek Kaubik Apidologie 30 (1999)
