So, theoretically, this type of repellant would be applied directly to the almond fruit, rather than during plant bloom? I'm just wondering about its effect on pollinators.

Thank you for your comment. According to chemical ecologist Walter Leal: "No effect on pollinators as the bees fly earlier and the repellent would be applied later in the season. In short, no overlap of NOW and bee flights."

This from Extension apiculturist Eric Mussen, UC Davis Department of Entomology: "The navel orangeworm can become a problem during almond-growing season when the moths lay eggs on developing nutlets, and the hatching larvae bore into the nuts. The larvae may consume the nuts, or they can injure the nuts enough to allow entry of a fungus that can contaminate the nuts with aflatoxins. Navel orangeworm moths become problematic long after pollination and fertilization of the flowers have been completed."
