First, all decisions on pesticides are based on the product, first and foremost. It has to have acceptable value. It has to have acceptable risks. If it doesn't, then that's it.
Every product that is registered goes through a risk assessment. It's only going to be registered if it's found acceptable. The bees would have been considered when the alternatives were registered.
That being said, I've talked to some of the growers myself. Chlorantraniliprole, a product that is currently available, is one that they find works, and to my understanding they've secured stock for the coming growing season.
