R&R Me and Yew and Me and a Dilemma

Yew (Taxus)
I am half way through weeding and mulching my 14 flowerbeds. While working on a bed I call "The Island of Unwanted Plants" (a bed mostly populated with shrubs I've pulled out of customers landscapes) I pulled out seedlings from my three Yews (Taxus). The seedlings were about the same size as the three I transplanted some 16 years ago when my wife brought them back from her parents house in Bush, Louisiana. Now the Yews are 8-15 feet tall, the shortest one having survived my accidentally mowing over it a couple times. It's always good to see a plant thrive in your landscape and it's especially nice when there is a connection to your past. As our ancestors immigrated to this strange new world I'm sure they brought plants from their homeland mainly to remind them of their former life. Coming from the Coastal South to the Mid South meant a lot of familiar plants just wouldn't work as well here as there so the Yews doing well has been nice. That's the good news.
Now for my dilemma: my Crepe Myrtles (Lagerstroemia) have Crepe Myrtle Bark Scale (CMBS). Fortunately, the infestation is not widespread, yet. In order to stop/control the spread of CMBS I took a sponge and a bucket of water and washed off as much as I could reach with my 8 foot ladder. I did this to three Crepe Myrtles and I was surprised at how quickly the water turned dirty. The need to frequently change the water made this a laborious process. So for a different three Crepe Myrtles I put on my neoprene gloves and " massaged" the bark, rubbing off the scale. This went a lot quicker though I must have looked like a nut to anyone passing by-talk about your tree hugger. My goal is to see how well each method controls CMBS. I'll be checking every few days to see if CMBS returns and if so how quickly; as that great Zen philosopher, Yogi Berra, once noted "you can observe a lot by watching".
My dilemma is what happens if this "hands on" approach doesn't work and I am left with the option to use a neonictinoid chemical to systemically removed the CMBS. Neonictinoids, chemicals such as imidiacloprid, have been linked to Colony Collapse Disorder in bees. These chemicals are indiscriminate pesticides and degrade very slowly. So the dilemma is how do you choose between  crepe myrtles and bees; to save one could harm the other. I try to be a good steward of the environment but I am not a 100% organic gardener. The potential loss of pollinators is a cause of real concern and I try to practice Integrated Pest Management, impacting the environment as little as possible, but where to draw the line.
Another example of this is the overuse of nitrogen fertilizer. With the Mississippi River draining over half the land mass of the continental United States the runoff of excess nitrogen has caused a dead zone in the Gulf of Mexico that is basically 80 miles by 80 miles just south of the mouth of the river. In addition, excess nitrogen causes algae blooms that periodically have killed off aquatic life off coastal Florida. Anyone with the answer, please let me know.

Since it's still Spring I'll finish with two short Emily Dickinson

A little Madness in the Spring

Image result for emily dickinsonA little madness in the Spring
Is wholesome even for the king
But God be with the Crown-
Who ponders this tremendous scene-
This whole Experiment of Green-
As if it were his own!

I cannot meet Spring unmoved

I cannot meet Spring unmoved-
I feel the old desire-
A Hurry with a lingering, mixed,
A Warrant to be fair

A Competition in my sense
With something hid in Her-
An as she vanishes, Remorse
I saw no more of Her.
