Topsin 4.5FL Fungicide does not have any insecticidal properties and should not harm bees as long as it is applied when the bees are not actively foraging on the given plant.
While Clearys 3336F and Topsin 4.5FL Fungicide do have the same active ingredient they are not made the same way so will have different labels for how each manufacturer developed, tested and got approval for their product to be released.
